Shit I’m sorry. I did the next task but never made the video. I’ll get it out, I promise. Spoiler, it think 88.5 grains of powder and the 300 grain bullet got me .24 Moa.
my rifle is a fierce short mag box single feeding as well. 3.720 coal. got a load with the 265 grain nosler long range accubond at 97.3 grains N570 for 2910 fps. it mite need a tiny bit more tweaking but if shot it out to 1175 meters so far. its shooting well.I just tried a few rounds with a neck bushing die running 1.5 thou of neck tension. to see if it was more accurate. .Im not sure that the neck tension is more accurate yet. Need to do more testing. Just loaded up a pressure test with the 265 nosler and the 250 Berger with retumbo .Hopefuly shoot them soon and try and find the flat spot in velocity .See if retumbo is as fast as n570. or not
Ive just started with a 338 Lapua and Berger 250 grain and N570. coal is 3.720. in my gun the 250 grain looks like its going to shoot around 99 grains for 2950 fps. but more testing is needed
This was my first time loading .338LM. I was able to get the majority of components from the manufacturers for this test so I'd say it was well worth it.
I actually ended up doing the second round of testing and never got around to making the video. The 300 grain bullet with 88.5 grains of powder ended up giving me just about a quarter of an inch at 100 yards. I never did really look into the breast weight. I have the two sets of targets, I can take a look to see if there’s any patterns. It will probably be too small of a difference to tell at only 100 yards though
Are you not able to do this on the lock n load press? I just purchased the LNL press but I’m having a hard time finding videos of reloading 338 using it
I’m not sure. People don’t usually use a progressive press for precision ammo. I personally only use it for bulk loading 9mm, 45 or .223 The powder drop is by volume, not weight, So it’s not not as precise. And I’m not sure if there’s enough clearance for the brass and bullet, although ive never tried.
