I see IMR lists their 800X at 8.4 grs. with the Hornady 200 gr. XTP at 34,200 psi. Lyman lists their lead cast, #2 alloy 401633, 200 gr. bullet at 7.7 grs. for 1181 fps. They, Lyman, list AA#7 at 10.2 grs. for 1184 fps. Both of these generate 28,200-28,400 CUP. E


Good deal.
In that case I will give AA#7 a whirl.

thanks,E.
