Yeah, non-polygonal rifling. I dont have a reason to do it until I can get primers. I have a few hundred LRN bullets to reload and I can get more. The lack of primers is alarming.
Also considering trading the G17 for 2 single action 357mag revolvers or a race double action revolver in .357. It all boils down to I love shooting. If I can't shoot 9mm then I'll shoot old school revolvers. Right now .38/,357 is more plentiful than 9mm. However, I will wait and see.
Bought some buckshot today for $3.99/5box. Pretty good deal all things considered. Before the shortages it was $5/5box. All stocked up now. I'm thinking about Weaponcraft's shotgun class. You never realize the versatility of a shot gun until you have a couple barrels for it. I'm good to go for everything from rabbit partridge turkey duck goose deer bear and all predators 2 and 4 legged.
