My buddy and I are just getting into the .357 sig both of us have glocks his is a G-22 with a lonewolf barrel and mine is a G-31. I reload so after buying dies brass and bullets I thought we would be off to the races,I have loaded for a .400 corbon in the past so bottle neck pistol cases are not new to me but the sig is turning out to be a pain in the azz to load right now I'm dealing with small primer flash holes going to have to drill out 1000 + cases also had to buy a tapered crimping die as the RCBS role crimp seems trouble some. Would love to hear from other .357 sig shooters /reloaders. Really looking forward to running full bore loads and 22rd mags. Twodogs.
