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.

I run standard .375 CT 390's at 3050 with no pressure in the low .2's with 36" Bartlein, 130 gr. retumbo. Like everyone else .100" jump. I pushed them to 3240 as max and started to open up to .5" and hammered brass with stiff bolt. Can't wait for the 410's to play with. Anyone found them yet?
I run 375CT with 400gr Lazers K&P 36in 1-7.5 twist with 131.5 N570 5 off the lands. This yields 3065AVG FPS SD 4.2 ES 12.1 over 10 shot group. I can push harder but groups open up so no need to push.
