I just slugged the barrel on my 9mm Colt SMG and ended up with a .357" groove diameter, when spinning the bullet in the caliper I see .3575, so it may be a little over. I'm working up a load with a 125gr (drops 130gr) Lee mold and powder coating. I coated these bullets a few years ago (had a few kids in between) and forgot to size them before loading them. They all seem to measure .358 so I think I'll be fine, just wanted confirmation, and what diameter I should size to with powder coated bullets with a .357 bore diameter? Thanks!
