I purchased some .356 diameter 9mm bullets from luckygunner today after reading .356 will work similar to .355 bullets in most guns. I read a few posts the last few days before ordering but was curious if anyone had any experience with these particular .356 121 gr JHP's in a auto 9mm/glock magazine'd 9mm upper for my AR pistol? Anything special I should do or look for if so? Ive reloded for many years but not as much in the last few years due to raising small children so any help/insight would be appreciated.
