No dubePA, 4831 can't possibly work. You see, the cartridge is overbore. confused

Funny thing, though, both the Powley Computer and QuickLoad predict 4831 is about the right speed for a .22-06 firing a 65 grain bullet. wink

Hmmmmm...

By the way, which version of the .22-06 do you have, and have you ever measured the water capacity of the empty case? Thanks.
