![]() ![]() 45-70 ammunition.Īccording to Mauser historian Ludwig Olson, the German entry was officially the 7.9x57mm in military circles but was called the 8x57mm in sporting use. Army was still issuing single-shot M1884 Springfields and blackpowder. Reacting to the French 8x50R Lebel cartridge, the Germans developed Commission Model 88 repeating rifles using 8x57mm smokeless ammo when the U.S. All had long FMJ-RN bullets weighing from 215 to 227 grains and posted muzzle velocities in the ballpark of 2,000 to 2,200 fps, including the 8mm Mauser cartridge.ĭating to1888, it is among the oldest smokeless-powder service cartridges and among the first with a rimless case. 30-caliber that appeared between 18 shared common attributes. In Europe and North America, then-new military cartridges of roughly. Sadly, as loaded in the United States, it is like a rejected calf: weak, underperforming, and failing to thrive. I might even have to break down some handloads to get a little to try.In many parts of the world, the 8mm Mauser prospers in the same performance niche where we place the. Turned out I'd forgotten to resupply after using up my last batch, and of course right now there's none to be found. Recently started an article on a certain cartridge, and discovered H322 would be a good one to try. It's the only way I can continue to experiment with different powders for various articles-and the reason I keep a running inventory of my supplies on my computer.īut even then I sometimes get caught short. ![]() Right now I have close to 100 smokeless powders on hand, because during the last "shortage" I often couldn't get powders (or bullets) from manufacturers, because everything they made was going out the door as soon as it got packaged. But that's another subject.)Īll of this is why a lot of handloaders keep a wide variety of powders. (I also believe this present shortage is being compounded by people who realized, due to previous shortages, that they could make "extra money" by reselling components. I do believe the "shortage" is already starting to wane-they always do, though sometimes it takes a year or even two to fill up the supply-line completely. 350-but the problem today is, of course, finding any. One of the best-known today is Trail Boss, which would probably work very well for reduced loads in the. IMR4759 was one, but IMR4227 also works well in certain loads. 45-70 to duplicate its original black powder velocities.Īll which is why we do have some powders designed specifically for lower-pressure handloads that burn more completely. But as I already noted, IMR4895 will leave unburned kernels when used in the. ![]() They burned a bunch of "war-surplus" IMR4895, and it did work better at what many would consider slightly under maximum velocities in various cartridges. But I believe that's also the reason so many handloaders who started during the post-WWII era tended to believe that loads slightly under maximum would be more accurate. ![]() IMR4895 is a classic example: It was originally sort of co-designed with the M1 Garand to burn best at around 50,000 PSI, because that was better for the M1's gas system. ALL can leave unburned granules when used in reduced loads, because they're designed to burn best at higher pressures. 308 as a full-power powder-but so do H4895, IMR4895, and a bunch of other powders of about the same burn-rate. I have mentioned here and there that 5744 works well in the. ![]()
