Hello All,
I've got a couple barrels to choose from in running through with my new .30 Gibbs reamer. I believe they are all 1 in 10" twist barrels.
Given the elevated pressures/velocities to be expected with the .30 Gibbs, what's the heaviest boolit I can stabilize with these barrels? Can I make a 260 grain from NOE work? What about a 235-240?
Thanks, all.
