Hello everyoneIm hoping someone could help with a couple questions that i had, so here goes.The first question is, i have a lone wolf 9mm barrel and after i slugged the barrel i got .356 inches, do i want to go .358 when i purchase a mould or just stay with a bullet mold that cast .356. The other question was, i noticed when i slugged the barrel i was getting .354 towards the middle of the barrel is this normal. I took measurements as soon as i popped the slug out and 20 minutes after Thanks in advance for any help, i tried to find some reading material on the subject but couldnt

In the 9mm load as large a bullet as will chamber easily and extract unfired rounds without resistance. This is chamber dependent and not bore/groove dependent. Most SAAMI chambers do well with. 357 whereas European CIP and NATO military usually require .358

Thanks ed I dont know if it mattered but this is a 9mm lone wolf conversion barrel for a glock 22. So if a .357 or .358 will chamber i would be ok. I also purchased a lone wolf 40cal barrel also to get rid of the glock bulge and it measures .401 so i would like to find a mould from noe swc that measures .402
