With the advent of the new 410gr berger hybrid, I got to wondering about a project I could put together for it. I’m considering a 375 Cheytac improved (Snipetac). But I was wondering what sort of velocity I would get out of this. I am intending on a longer barrel (38”). I have seen some with the same chambering achieve about 3150 with a 400 grain MTH cutting edge with a 36 inch barrel. Given how the cup core bullets generally run a little slower than the solids, should I assume the new berger, with it’s slight to weight gain, to run about the same (3150 fps) with a slightly longer barrel? I haven’t seen very much data for the improved variant of this case so I’m kind of unsure of what to expect any and all information would be greatly appreciated.
