All three cartridges are relatively popular among reloaders and handloading components are widely available. It is a beltless, rebated rim cartridge based on the .300 Remington Ultra Magnum case shortened .090" and necked-up to accept a 0.338-inch (.338 caliber) bullet. We know accuracy is important and in the end we think when looking at the .300 Win Mag vs .338 Lapua Magnum, both cartridges can be extremely accurate when used with the right platform and in the right hands. For simply comparing cartridges we have left this part out, but understanding your bullet design, how it expands, and the velocity needed for proper expansion and penetration is a huge part of successful hunting. 20ft.lb of recoil energy is thought of as enough to cause flinching and negatively influence shot placement. Both cartridges shoot the same diameter bullets, but the 338 Lapua normally uses heavier and more aerodynamic bullets with a higher sectional density than the 338 Win Mag. It also makes sense given the huge increase in recoil that we just discussed. I own both. It is a beltless, rebated rim cartridge based on the.300 Remington Ultra Magnum case shortened.090" and necked-up to accept a 0.338-inch (.338 caliber) bullet. So, carefully analyze your potential needs and purchase the one you think will fit them best. 230gr/3000fps .823 (G1) .414 (G7) The .458 Winchester Magnum came first in 1956 and was followed by the .338 Winchester Magnum and the .264 Winchester Magnum during the next couple of years. The primary difference between the 338 Win mag and the Lapua is in performance. But in general, they’re all relatively flat shooting cartridges (though not quite to the extent of some of the popular high velocity varmint cartridges). Both of these cartridges have really high bullet momentum numbers for hunting cartridges, but the .338 is overly impressive. I’m just afraid it will be a year until we see the Berger 245’s Really hoping the … There are also some very important differences between the three cartridges when it comes to bullet size. I also set throats to offer the best match seating bullets ideally for those I plan to use. This kinetic energy associated with the bullet is transferred to the target on impact and can cause massive damage to the surrounding tissues and organs. This beast provides more initial velocity than any of the previous cartridges discussed, and has proven to be an outstanding elk cartridge. 30 Nosler Stopping power is critical, especially to hunters for several reasons. I was wondering when it comes to very log distance aplications how does the 300 remington ultra mag hold up to the 338 lapua. If you’re driving out to a spot to sit, it doesn’t matter, but for hunting situations where you might be logging a couple of miles, that extra 15lbs is going to be fatiguing. The 338 Winchester Mag same as the 300 but a better all around cartridge IMO. Even proven premiums like Nosler Partition and Woodleigh SP can suffer jacket separation when impact is north of 2800 fps or thereabouts. The momentum gives us an idea of how well a round can overcome resistance. The .338 LM is better reserved for larger game, and we are talking moose and larger, like Africa Big Five larger with over 3,500ftlb even at 300 yards. Like the other new Winchester belted magnums as well as the 7mm Remington Magnum, the .300 Win Mag also utilized a shorter case that fit in a standard length rifle action. The .300 Win Mag, one of the flattest shooting cartridges available, and especially when maximized with hand loading has several excellent factory loads for long range shooting as well. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges.As you can see, the .338 Win Mag has a little bit (~16% more) more free recoil energy than the .300 Win Mag. In addition to having a really long effective range, the cartridge is also (allegedly) capable of penetrating military body armor at ranges in excess of 1,000 yards. The .338 is also able to be fitted with much heavier bullets than the .300 Win Mag rounds. .338 Remington Ultra Magnum history and performance. Lapua Unprimed Brass Rifle Cartridge Cases .300 Norma Magnum 100/ct. Unlike the 300 Win Mag, the 300 Ultra Mag is a more versatile cartridge for all shooters of every range. Overall, when looking strictly from an angle of the .300 Win Mag vs .338 Lapua Magnum, there is not a huge difference in the long range trajectory of these factory loads. We’ll discuss this more in a minute, but since the cartridge is designed primarily for long range shooting and has such a heavy recoil, the .338 Lapua is most commonly available in very heavy rifles that dampen recoil, but are more difficult to carry. At the same time, the .300 PRC actually has a tiny bit shorter case length than the .300 Win Mag (2.62″ vs 2.58″). It also has a higher maximum SAAMI pressure of 65,000psi. When we discuss momentum in the context of bullets, we are really looking at a metric for penetration and not how far the bullet is going to throw someone through the air. The US Army is converting over to this caliber and the 300 norma mag and dropping both the 300 win mag and the 338 lapua. Prices and availability vary from region to region, but the .300 Win Mag is by far the most common and least expensive. ... No doubt the 300 ultra is no slouch and a lot easier but starting from scratch the Norma really has my attention. Which is pretty impressive for the .338 LM to be so much heavier without falling that far behind in velocity. Itâs just something to keep in mind, especially if you wander into the world of handloading. Wind drift and drop are both less critical with that extra speed. On the other hand, since they don’t require a really long barrel or a heavy rifle for best performance, the .300 Win Mag and .338 Win Mag are both manufactured in a number of really good bolt-action hunting rifles. Even the semi-automatic Browning Automatic Rifle is produced in both .300 and .338 Win Mag. I have a thing for long range shooting . By the same token, the .338″ bullets used by the .338 Lapua and .338 Win Mag are also used by the .338 Federal, the .338 Ruger Compact Magnum (338 RCM), the .338 Remington Ultra Mag, the .340 Weatherby Magnum, and the .338-378 Weatherby Magnum. Before we get started, I have an administrative note: Some of the links below are affiliate links. Great read. i just picked up a s=Sako m995 in .338 lapua. The problem is that most .338 Lapua rifles are specifically designed for military use and/or civilian long range precision shooting and are therefore expensive, very heavy, and have a really long barrel like the Accuracy International AXMC, the Barrett MRAD, or the Sako TRG. We will come back to all of this in the application section, but we do want to note that in a lot of cases, either of these cartridges have more than enough momentum to drive a round through the target. He used that rifle and cartridge to kill two Taliban machine-gunners 2,707 yards (2,475 meters) away in Afghanistan’s Helmand Province during 2009. From this example, we see that the .338 LM round is showing an overall flatter trajectory than the .300 Win Mag round with the biggest difference being 10″ at the 500-yard mark. When averaging the rounds between the two cartridges, there is a .05 difference in SD between the .300 Win Mag vs .338 Lapua Magnum. To answer your question: no, you cannot shoot 338 Win Mag out of a 338 Lapua rifle. Barrett's M99 is a great single shot. The 338 Lapua shoots larger diameter and heavier bullets that are generally more aerodynamic than the bullets the 300 Win Mag uses. The table shows that the 338 RUM delivers equal velocities with less powder and less recoil up through the 250 Grain bullets. Really don't want another lapua bolt face either. With that being said, we will note that .338 LM do use larger caliber bullet compared to the .308 and when looking at the same bullet, youâre going to have a larger wound created with the larger caliber bullet. Due to its longer case length and the difference in placement of the shoulder, the .300 Win Mag does have a slightly greater case capacity than the .338 Win Mag. We have also provided the average cutoff for supersonic speeds. No belt to deal with in FL resizing. The 338 Lapua has nearly twice as much recoil energy though. While all three cartridges appear well suited for hunting many species of big game at first glance, this is where their real world performance really starts to diverge. The sectional density correlates with the amount of penetration a bullet will have on target and since we are not looking at bullet types and designs in this article is a good standard for comparison of the two cartridges and the rounds we have selected for each. However, there are honestly very few hunting situations that require a cartridge as powerful as the .338 Lapua. There are rounds with higher velocities from the muzzle out to 500 yards, but it is dependent on the specific round. We have compiled the velocity data from the ten rounds from the manufacturer’s website, and when we look at the velocity (ft/s) (Graph 2) from the muzzle to out to 500 yards, we see some interesting points of discussion. 215gr/3150fps .691 (G1) .354 (G7) .338 Lapua VS .300 Remington Ultra Mag? Buller design and their BCs influence the trajectories as well as velocity. In this article, I’m going to discuss the pros and cons of the 300 Win Mag vs 338 Lapua vs 338 Win Mag so you can make an informed decision regarding which cartridge fits your particular needs the best. Now that we have taken a look at the performances of the .300 Win Mag vs .338 Lapua Magnum for several categories, we can begin teasing apart in which situations each cartridge might be better suited. Even so, the .338 Win Mag is not rare by any stretch of the imagination and rifles like the Browning X-Bolt, the Mossberg Patriot, the Ruger American, Guide Gun, and Hawkeye, the Savage 110, the Tikka T3x, as well as the Winchester XPR and the Model 70 are available in both cartridges. The .300 WM mag rounds have an average of 80lb/ft.s of momentum leaving the muscle and 58lb/ft.s at the 500 yard mark while the .338 LM rounds dropped to right around where the .300 WM rounds started. Only thing I see different about my rifle is it only ways 6.5 lbs and has a trigger weight of 1.5 lbs. I feel like I’ll be less of an idiot around my friends now. I’m not trying to discourage anyone away from the 3 fine cartridges which are the subject of the article, but if you are new-ish to shooting, or new to magnums, there is a very big difference in shooting them than there is for the non-magnum small bores (30-06 and smaller). Letâs start out with talking precision and long range shooting. The .338 LM rounds have a much higher kinetic energy than the .300 Win Mag rounds throughout the 500-yard range except for the .338 LM Hornady SP-RP Interlock 250gr which falls into the .300 Win Mag range at the 400 and 500-yard mark. They also are large enough cartridges that with proper expansion you are going to have enough of a deep wound creation for a quick kill with a properly placed shot. The following ammunition cartridge ballistics information and chart can be used to approximately compare .300 Weatherby Magnum vs .338 Lapua Magnum ammo rounds. The Lapua cartridge also uses a larger, .588″ rim diameter. And once we get out to the 1,000 yard mark, the .338 LM has actually lost less altitude than the .300 Win Mag round. Thank you. good read!

Of course, it is an average and as we stated above, there are pretty high performing .300 Win Mag rounds available and there are .338 LM rounds that are closer to the .300 Win Mag average. We also saw much higher ballistic coefficients for the .338 LM rounds than the .300 Win Mag rounds, though both have high BCs when compared to other types of cartridges. With that said I have to say you write very well balanced articles making real efforts to not let personal bias in. Winchester didn’t stop with the .264, .338, and .458 Win Mag cartridges though. Like we saw with the smaller set of rounds, there is a wide margin of difference between these two cartridges. Nearly all modern cartridges are flat-shooting out to about 300 yards (assuming a 200 yard zero). .338 Remington Ultra Magnum history and performance. The energy that is carried by the bullet is only one factor of a round’s stopping power, but it is an important one nonetheless. Around that same time, the “Magnum Era” also began in earnest when Winchester rolled out a line of new belted magnum cartridges utilizing a modified .375 H&H case. The .338 LM was designed and produced in the late 1980’s. Remember when I talked earlier about how the designers of the .338 Lapua wanted a cartridge with good long range performance without requiring as large or heavy of a rifle as the .50 BMG? Likewise, the .300 Win Mag rounds vary between 0.481 to 0.64. many of my customers hunt Africa and usually use larger bore bullets. However, the .338 Lapua can generally use heavier bullets than the .338 Win Mag. 300 Win Mag Vs 338 Lapua. Certainly making me 2nd guess my desire to eventually obtain a .338 Lapua. The sectional density of the .200″ round is going to be higher, and it should penetrate deeper than the .300″ round. I have seen 30 inch barrels in 338 Lapua and Remington Ultra mag shoot 2900 to 3000 with 30 inch barrels with 300 grain bullets. I accidentally put the SD of a 275gr .338 bullet, not a 270gr bullet. Even so, the .338 LM rounds are significantly more expensive than the .300 Win Mag rounds. The ammo cost is pretty insane. It has an incredible G1 BC of 0.789 and shows one of the flattest trajectories of all the rounds we examined making shot adjustments much less severe. The 338 Lapua does best with 250 to 270 gr bullets, although the 300 gr SMK is a serious contender for long range accuracy. How much this impacts accuracy falls more on the user’s experience, and we’re not going to go into if this would give one cartridge an advantage in accuracy, but it was worth mentioning. Both are impressive, especially when compared to other hunting cartridges, but just in the context, the .338 LM has the slight edge. It influences recoil, it influences trajectory, and it even influences stopping power of the bullet, and that is only the categories that we are looking at specifically in this article. That’s approaching safari rounds. Specifically, the designers of the .338 Lapua were trying to build a very accurate and flat shooting round that was more powerful and had a longer effective range than the 7.62x51mm NATO, but did not require as large or heavy of a rifle as the .50 BMG. 338NM where distances are long and game is larger. The increased interest in the .338 LM in civilian circuits has resulted in more round options though still limited compared to other competition and hunting rounds. Below are the averages for the two cartridgeâs sectional density. Even so, I don’t think you can go wrong with the .300 Win Mag for any of those species during a hunt in Africa, North America, Europe, New Zealand, or elsewhere. Choosing the better one really depends on the hunter and the exact situation, but due to the aforementioned issues, the .338 Lapua isn’t a practical choice for most hunters. Of course, the difference is less than three inches at the 400 yard mark and less than that at all of the previous yard markers. The .300 Win Mag is a 30-cal bullet that came into production by Winchester in 1963. It is between the 338LM and the 338Win Mag. The first two are self explanatory, the Edge is a 338×300 Remington Ultra Mag. The author analyzed six .338 caliber magnum cartridges (.338 Winchester Magnum, .340 Weatherby, .338-378 Weatherby, .338 Remington Ultra Mag., 33 Nosler, and .338 Lapua) for trajectory, effective range, and recoil with modern ballistic software available free online from shooterscalculator.com. Thanks for your comment Kirby, glad you enjoyed the article. None are really known as classic sheep or mountain hunting cartridges, but once again, I’d lean towards the .300 Win Mag since it has a very flat trajectory and lighter recoil. Grund genug, es einem Test auf 100- und 300 m zu unterziehen. While both of these rounds are known as having the capability to be used in long range situations, both are also used in a hunting capacity, which means shots taken at a shorter range are probable, so we will also take a look at the short range trajectories. The .338LM rounds lost momentum at a slightly lower rate than the .300 Win Mag rounds. On average we are looking the pretty large differences between these two cartridges; Muzzle (989ft.lb), 100yds (897ft.lb), 200yds (859ft.lb), 300yds (799ft.lb), 400yds (741ft.lb), and 500 yds (688ft.lb). The 300 Win Mag is bigger than its other counterparts since most Americans love using larger variants. It saw service with the military in both Afghanistan and Iraq and is still in use with military personnel today. So while these numbers can vary, the general trend of recoil energy between these two cartridges remains constant.
