I have been using 50 BMG and US 869 with the 375 and 400 gr . The 375 gr with 142 gr. of BMG yeilded 2960 and 148 gr of US 869 yielded 3080. The 400 gr was pushed with 140 gr of BMG for 2850 and 146 gr of US 869 yielded 3010 fps.

They dont seem to be fussy about seating depth, start with a case trimmed to standard length and kiss the case mouth with the seal tite band for a starting point. I suggest that you refrain from seating the seal tite band into the case mouth because it seems to cause run-out problems.

Looking forward to the updates from the testing. I ll be trying some GS rounds in my 375 Allen apart from my snipetac. The reason is the AM is 10 twist. Anybody tried any GS 416gr?

Don't you mean the 414gr GSC ?? They quote a 8.5 twist to stabilize this.
GSC 355gr should work in a 10 twist.

RM I ll be trying the 355 GS in the 375AM since it is a 10 twist not the 414 gr as you correctly point out needs a faster twist. I asked Kirby and he had not tried them. I m waiting to see what the tests show by others on whether a progressive twist is needed for the 414 before deciding on a new barrel. My mistake was saying 416 gr but ment has anybody tried any GS or other Vld high BC rounds in a .416 caliber or similar - apologize. I realize their is the 408 cheytac but have been thinking of trying the snipetac in . 416 and the big . 577 case.
