Rounds that left the muzzle at higher velocities than some of the .338 rounds have now fallen below them. We can see an increased BC for the .338 LM rounds when compared to the .308 Win rounds. Most hunters look for at least 1,000ft.lb of kinetic energy when dealing with whitetail size game. The .308 is a fairly popular medium to large size game in North America and has been so for decades. To deal with recoil such as this, you should be looking to get some ballistic or stopping power advantage out of the deal, and we will see if this cartridge provides it. The trajectory wasn’t much of a factor at distances up to 300 yards, though we did see the .308 Win rounds show on average more bullet drop as we moved out past 500 yards. The .308 Win has been and still is one of the most effective short action cartridges for medium to larger game in North America. While there are big differences among the (left to right) .308 Win., .300 Win. While data gathered in this method provides an accurate means of comparison, we want to make clear that the numbers can vary when used with your shooting platform. The fundamental specifications and dimensions of the.308 case remain the same, meaning the.338 Federal brass can easily be formed from.308 Winchester brass. She can drive tacks with her purple gun at 100 yards. Best 9mm Ammo 2019 [Self-Defense & Target], 6.5 Creedmoor vs .243 Win – Cartridge Comparison, Best .40 S&W Ammo: Self Defense & Target Practice. 1000 yards? This is just our opinion, and honestly, there are a lot of rounds that we like. The .300 win mag is no slouch either carrying a full 2000 ft lbs of energy at 500 yds with the factory 200 grain weight and a flatter trajectory than either the .338 or 30/06. We see that there are two .338 LM rounds leave the muzzle at much higher velocities than the other .338 and .308 Win rounds. It shoots like a .243 Win. Even so, both of these rounds stay supersonic throughout their flight and will deliver the proper terminal performance throughout this range, a plus for both cartridges. The .338 in (8.6 mm) is the caliber at which medium-bore cartridges are considered to begin. Accuracy in 'standard' (non-Kimber rifles) is mediocre. What are we talking about with energy concerning the cartridge? The 338 win mag is by far the superior performer of these two. While this doesn’t translate directly to accuracy, it does give you an indication that the .338 LM rounds are going to be easier to handle in less than ideal weather conditions, especially at long range. How many clays do you think the 180gr 308 will go through? And they are just guidelines as again, shot placement can make up for being a few hundred ft.lbs off. For hunting, the cartridge that will be better suited for you all depends on the hunting you are doing. For hunting anything on the North American continent they’re both sufficient. Winchester took their .458 Winchester Magnum case—itself a shortened and blown out .375 H&H case—and necked it to hold the .338″ diameter bullets the company used for its rimmed .33 Winchester. Even with the increased rifle weight, we used with the .338 Lapua Magnum rounds we still see a definitive increase in recoil energy when compared to the .308 Win rounds. By looking at a wider selection of rounds with varying loads, bullet designs, and weights, we can see if this trend is more general towards the cartridges. The .338 Winchester Magnum is a .338 in (8.6 mm) caliber, belted, rimless, bottlenecked cartridge introduced in 1958 by Winchester Repeating Arms.It is based on the blown-out, shortened .375 H&H Magnum. The following ammunition cartridge ballistics information and chart can be used to approximately compare .308 Winchester vs .338 Lapua Magnum ammo rounds. As you can see, this makes the BC an important factor when comparing cartridges and is of importance for hunters and range shooters alike. In doing so, we hope to differentiate what these cartridges are capable of and in what situations one would serve you better than the other. For the .338 LM, we like the Hornady ELD Match 285gr rounds. By streamlined we mean aerodynamic.

This includes recoil, trajectory, and terminal ballistics such as penetration and bullet expansion. We hope that this article has shed a little more light on the two cartridges and given you a better understanding of the two and allowed you to make more educated decisions on if these two cartridges fit what you need. We will take an in depth look at the 338 Lapua vs 308 and hopefully come out on the other side with a better understanding of both. That weight makes a big difference in ME with the 300 win mag doing 3500 ft-lbs at the muzzle compared to the 338 lapua’s mighty 4832 ft-lbs. I seldom shoot the big guns anymore with the .308 or 30/06 being all I need(and more) for deer. The importance of looking at recoil often deals with the potential for throwing off a shot. In our ballistics section, we will take a look at several categories including the velocity, ballistic coefficient, and the trajectories of the ten rounds we have selected for comparison. In this rifle caliber comparison, we are going to take a look at two cartridges that most might not think to compare. The numbers of this cartridge all point towards it being a highly effective hunting round for large game. We have compiled the SDs of the ten rounds we have been using for comparison. On average, the .300 Win Mag does have a flatter trajectory with a difference of .78” (300yds), 1.96” (400yds), 3.76” (500yds), 5.74” (600yds), and 8.54” (700yds). We compiled the velocities (ft/s) from the muzzle out to 500 yards from the manufacturers’ websites (Graph 2). Again, this is something to keep in mind once we reach the application section. Mag., they all kill elk quite handily. Ever since the advent of the first metallic cartridge (the 22 BB Cap in 1845,) hunters have demanded rifles, cartridges and bullets capable of terminating everything from ground squirrels to elephants. Here's a short Black bear hunt with my friend's, Dion and Nev. Dion took a nice black bear after having some great SE Alaska weather. The .308 Winchester has the smallest frontal surface area (also known as cross sectional area) of the bunch at .0745 square inches. For the .308 Winchester, it’s tough to narrow down our pick for a hunting round even when just looking at the five we used for comparison purposes. Very hard hitting round and great at long distances. We plan on using this one for stopping cars after shtf. 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. is quite versatile and a solid contender as a black bear cartridge. Bullet weights of 200-, 250- and 300-grains were initially offered for the .338 Win. These numbers are going to be critical when we reach the 308 vs 338 Lapua Magnum application section. vs. 338. And again, these are not the only parts to the full equation. The .308 has been utilized by military and police forces since its introduction though not as heavily in modern times. With such higher BCs, it will be interesting to see how the selected rounds stack up in other performance categories. While the .308 will kill most North American game fairly effectively, the .338 will HAMMER really big game. Because the .338 federal is just a .308 necked up, there is not a lot of powder to propel the big .338 bullets that have they really high BC's (250-300 grains). 308 vs 300 Win Mag How Many Clays Will They Shoot Through? While the .308 Win rounds have a smaller diameter than the .338 LM rounds, they are much lighter which causes the drop in SD numbers. was taken in a 24 inch barrel, while the .330 Dakota data are for a 25 inch barrel, with 26 inch barrels used for the .340 Weatherby and .338 RUM. But for new hunters: 308, every damn day of the week. Penetration is the second category that we will look at as it pertains to stopping power.

There are without a doubt major differences between these two cartridges, and it will be interesting to see how these differences affect the performance characteristics. Mag. While there are some who can take a .308 and do amazing things with it at these distances, overall the .338 LM is better suited for long range precision shooting. This means that the momentum of a rifle's reaction will exactly equal the momentum of the bullet and powder gasses ejected from the barrel. The following ammunition cartridge ballistics information and chart can be used to approximately compare .338 Lapua Magnum vs .338 Winchester Magnum ammo rounds.

Immediately after the .338 Win was released, target shooters necked the case down to .30 caliber to produce the highly regarded .30-338 Wildcat. In the simplest of terms, a ballistic coefficient is simply a number that is derived from several variables taken from the cartridge specs including the bullet. And while these are only three of the components, by looking at all of them we hope it makes the differences between cartridges a little more clear and provides you with more information to base your decision. Now that we know how these bullets behave in flight let’s take a look at if they have the force behind them to be useful. You can see the heritage of these cartridges on display in the photos below. If you are one of the latter, let’s look a bit closer at what the BC is and why we consider it important enough to include in this article. A 308 will out perform the 338 at long range, though that does not mean the .338 federal is not a good cartridge, it just was intended for a different purpose. Knowing how it behaves and its limitations lets you take full advantage of the different situations you will be presented with. So we will take a look at the components we can, but keep in mind that there are other factors you will have to take into account. These bullet weights and speeds also resulted in rounds with excellent ballistic coefficients which gave the .338 LM excellent trajectories at long range. If you compare individual rounds, the flattest .338 LM round shows nearly 40″ less bullet drop at 600 rounds compared to the steepest falling .308 Win round and 56″ less drop at 700 yards. We also like Nosler’s AccuBond bullet for punching through really tough hide while still expanding for maximum energy transfer. 300 Win Mag vs 338 Lapua vs 338 Win Mag: Picking The Right Heavy Hitter. Stopping power is a topic that is going to seem a lot more valuable to the hunters reading this article rather than those just looking to use one of these rounds for target shooting. For certain situations, sure, but there will always be some point where one bests the other. The 340 wby will shoot just as accurate as anything else with velocities in bullets up to 250 grains very close to the ultramags. There are a lot of obscure rounds that some avid hunters or marksmen might not have heard of, but we would be willing to bet a large sum of money that anyone you speak to who has owned and used a rifle has heard of or handled the .308 Winchester cartridge.

Depending on what game you are hunting, the amount of penetration you will need will vary. At 200 yards the velocity is 2361 fps and the kinetic energy is 2476 ft. lbs. Call me a wimp, but the 338 win mag with 250 grain bullets generates about 40 ft lbs of recoil, no thanks! If you have ever seen a video of a bullet passing through a ballistic gel, you get an idea of this energy. But since we have to make a pick, we like the Federal Vital-Shok Ballistic Tip 150gr round. Because of this, you are going to have a much easier time finding ammunition and a wide variety of ammo.
