Three 22 250s ! In my 43rd edition lyman manual it's 40 grains of 4064 and 3855fps, not that I put too much faith in book velocities.
I've noticed over the years that all manuals seem to dial back for whatever reason.
When I start reloading I will probably use the lyman starting point and go from there.
I now have barrel envy, mines only 25 inches.
