just make one walk outside and fire it into the ground on your lawn

adjust if necessary

the best you can ask for is a starting point which would be 10 grains if you want to be safe and probably 8.5 gr if we had to place bets

with unknow bullet(major problem) and unknown cases(minor problem) capacity isn't known
changing from win to fed primers messed my sub load up

subs are the only thing Iv found this far that have benifitted from a crimp if you happen to have dies that do that
reduced the group from 4 inches at 30m to an inch with lead cast

52.2 grs of water for the 7-08 and 55.6 grs for the 7x57

so its basically a 308 case capasity pushing basically the same weight as my ballistic tip load which I used 8.2gr TB on
fed primers/165ballistic tips/ppe cases
