:Are you Annealing your brass timxit. Don’t let the “.340” fool you. Based, as the name implies, on the .30-06, this efficient number was produced by A-Square beginning in 1998 and later by Nosler. While the 1000yd performance is excellent, there are much more efficient ways of getting equal and in some cases better ballistic performance at 1000yds and less. I can’t confirm what pressures Sierra used to test these cartridges, but the data is scientifically acquired. how many times can you reload the 338 rum brass before you see signs of separation or is just a good safe time to discard them, That depends on a lot of factors This one really ups the ante in the 8.6mm sweepstakes. Still, if you want to shoot big game at big yardages, the .340 Weatherby Magnum is tough to beat. ISS Prop House gives us the rundown on the guns used in Enemy at the Gate. I have looked at the 340 WBY, 338 RUM, 33 Nosler, 338 Win Mag, and have chance to pick up a 338 RCM. Introduced in 2008, this short-action number (case length is 2.01 inches) churns up some pretty impressive numbers—a 200-grain Hornady SST at 2,950 fps and a 225-grain InterBond at 2,750 fps. In other words, it offered a combination of velocity, range, and throw weight sure to appeal to big bear hunters in Alaska, moose hunters, and elk hunters who simply wanted more bullet diameter and weight than was feasible in a .308 bore size. Dec 1, 2016 #2 W. waveslayer Member. i dont plan on hunting with it unless i can go varmint shooting at long range. Trail Boss, 5744, and 4759 are not dirty words. Good for North America’s larger game. But let’s take a look at the 8.6mm (that’s .338 for the metrically challenged). It has become the standard .338 caliber test round for the Nosler Ballistics Lab. If you are punching through the same bullet hole I would not change a thing and at 2,850 fps that is not slow ether. A 338 Lapua mag firing a 250gr Scenar at 2960 would have a drop of 24.25 MOA and 5.25 MOA windage for the same range/conditions. Copyright © 2000-2020 24hourcampfire.com, Inc. All Rights Reserved. Which brings me to the point of the 338 bore and learning the nuances of shooting great distances. I can load up to 97gr of powder but I keep it at about 93 because that is my most accurate load. That's why I would have a custom built for that price. The first two are self explanatory, the Edge is a 338×300 Remington Ultra Mag. But, heck, if you can afford to go and hunt the game that requires that sort of ballistic muscle, paying $6 a pop is the least of your worries. For those who take large game at or near 1000yds the energy provided by these cartridges is ideal.
The military rationale for the .338 Lapua Magnum? But you're gonna have to handload, as there's no factory match ammo for it. Mag.
The 338 RUM delivers surprising accuracy for a large magnum cartridge. I am shooting a McMillan TAC338,27 1/2"Schneider bbl,10"tw. It’s also notable that to build a rifle in 338 lapua a standard magnum bolt face would not work, requiring a little more work by your gun smith (my smith only charged me around $30 for this, but your mileage may vary). By all accounts, it succeeded. While the firearm was ordered without a muzzle brake; about twenty rounds later that mistake was remedied. I was considering a 33 Nos but lack of brass options has me going with either a 338 rum or edge Looking to shoot a 265 ABLR around 2950 in a 26" barrel, I have an action cut for a 4" box so I can throat accordingly.
JavaScript is disabled. The .338 RUM is balistically identical to .338 Lapua. This is a big difference in reloading cost, although a straight across comparison would probably not be fair to the Lapua. i dont need a 338 for what i hunt. !that's my point exactly- does it take two guys to carry the rifle? That being said, I personally use Lapua brass when it’s available for a cartridge I’m loading. Despite the enormous sales success of the now-ubiquitous .223/5.56, in terms of big-game rifles, the United States is a .30-caliber country—and probably has been since the Model 1894 Winchester. I managed to dial it in—mercifully—in about five or six rounds. This one’s a bit of an anomaly in our bolt-centric .338 lineup. This is specifically due to high BC mass produced bullets available. :Neck re-sized or full length It doesn’t seem to be as popular as it should be, and that’s a shame. Other factors weigh in like accuracy (low ES and SD) as well as temperature sensitivity etc. Their complaints included not being able to close the bolt on the new brass, and that the Bertram brass needed to have the shoulders bumped back. In “most” cases the neck will split first. This 2.6" group at 1005 yards is from my 338 RUM shooting the 300 Berger EH. While nearly any medium to slow burning powder will work well in the big RUM, IMR 7828 and H1000 are particularly good choices. The biggest difference in my opinion between these cartridges is reloading cost. One is made by Savage the other is Remington. The .375 RUM is well suited to dangerous game or long-range big game, but not for benchrest. There is great debate about the velocities these cartridges can produce in relation to each other.
Shot a cow elk at 680 yards last fall, she fell instantly.
The .33 WCF can pretty much be considered the godfather of American .338 cartridges. These guys that ask questions like this???? I would argue that this is the most sensible conclusion since it follows the general capacity/pressure model (please do not take this to mean I view forum opinions as scientific data). |
hey Garco, do you have any dummy rounds made up for it you might part with? Recently, the most popular long range 338’s are the 338 Remington Ultra Mag, 338 Lapua mag, and 338 Edge. Accuracy is very good,probably would be better in trained hands. Since it appeared five years prior to its .300 Win. I'm over book speed with a book minimum charge based on the Hodgdon website. The 338 RUM, and 338 Edge (wich uses 300 RUM brass) can be had for around $80 for 100pc. I have been using SMK 300gr @ 2730fps. All Rights Reserved. Point and shoot. Early in my days as an associate editor at Guns & Ammo (we’re talking mid-1970s here), I was “asked” to zero a Weatherby rifle so chambered for one of the higher-ups.
To split the difference (roughly speaking) in effective range between the 7.62 NATO and the .50 BMG and do so in a rifle platform with less weight and bulk than those chambered to the .50 BMG. If this has any merritt, it’s likely due to higher brass quality available for the Lapua. Like I said at the beginning of this report, if you want more long-range knockdown power than a .30-caliber round offers, you can find it under the .338 umbrella. This is specifically due to high BC mass produced bullets available. It features 200-, 225-, and 250-grain bullets at velocities ranging from roughly 2,550 fps to 2,750 fps and will handle just about anything in North America. If you go big bullets and push them moderately, you may have the same point blank range as a .308.
Ok last 338 post.. It is most commonly referred to as the 338″Edge” due to Shawn Carlock of Defensive Edge who is the biggest proponent of the cartridge and has, by far, the most experience with it.
Maybe the .338s haven’t kept pace with the never-ending avalanche of .30s, but they look to be running a close second (well, at least until the 6.5 breakthrough). Sierra game king. Of course, in those days the rifle was one of the old high-gloss walnut-stocked, high-comb Mark Vs with the rollover cheekpiece. While it takes a great deal of powder to push a 250gr to 300gr bullet at acceptable velocities for long range shooting, the performance has trumped the cost in the minds of many shooters (not to mention military and law enforcement world-wide). If one does a quick search you’ll quickly find excellent long range accuracy can be had by the RUM and Edge. It gives essentially identical maximum velocities for the bullets in question, although the RUM was reaching them with a higher percentage of the powders tested. All Shooting Times subscribers now have digital access to their magazine content. By the time the four molds for that bore are wrung out the only wear and tear will be on the tires of the truck traveling to our 600 yard range. hi Right now, my break in and practice load is a 300gr SMK at 2710fps using 8133.
338 Remington Ultra Magnum Rifle Cartridge, Abbreviated Name: 338 Rem Ultra MagAKA: 338 RUM. ©2020 Outdoor Sportsman Group. I plan to shoot this firearm hundreds and hundreds of times. The parent case was the .376 Steyr, which was necked down and given a thicker web. In October 2000 took a 6×6 bull @ 597 yds, a bear @ 853 using 250 gr. The most popular consensus (from what I’ve gathered) is the 338 Edge is the fastest followed by the Lapua mag, with the 338 RUM not too far behind. That was an amazing firearm; with an H870 (no pressure signs load) it would chronograph an honest 3100 fps with the 300 grain Sierra.
If it weren't for that, the Edge kicks butt. The .338 edge and the Lapua are almost balletic twins. That is using H1000, Norma 300 RUM brass, and Federal magnum primers. I seat at 3.70" and I'm right at the powder level with the base of the bullet.
