I have a XP100 that has been rechambered to a 7 Lazer. (longer than a 7 BR shorter that a 7 IHMSA)

The load data I have recommends 30.5 grains of H4895 for 140's - 150's.

I would like to work you a good load for deer and antelope using 140 BT's.

Should a try a little slower powder? If yes what?

Thanks much.

John
