Thanks for the replies.
I have some IMR 4320 & 4350 from 243 Win tests, some Varget for my 22-250 and LEVERevolution for my old 30-30.
So.... looks like we'll pick up some 4895 or S759 (whatever LGS has) and start there. I think the bullets he has are 87gr, but I'll verify this before we head to the LGS. Bob is the type not to purchase a specific tool if he's already got something that can be made to work so this 250 Savage which has done deer & hogs for his brother will be forced now to "do it all" including woodchucks for Bob. Hopefully the "I need another gun" disease I have will rub off onto him and he'll buy my 22-250.
Thanks
