Hello all. Long time lurker but new shooter and first post. I’ve only fired about 1500 rounds through handguns so far, as I just got into shooting a few months ago - so I apologize if this is a dumb question. I tried the search tool and browsed around past threads a little but still thought it would be best to ask people who know a lot more than I do. I have a box of 147 grain 9x19 federal HST’s and I noticed that about 17 of them have small dents in the casing. They seem to be very minor and most of the dents aren’t even deep enough to feel with a thumbnail. In fact, most aren’t even visible without direct bright light. I was just wondering if this would adversely affect the pressure or reliability, or if the casing would take on the shape of the chamber when fired? There’s no noticeable sign of setback, and none of them have been chambered into the pistol, but they have been loaded and unloaded into magazines. This was the first box of defensive ammo I bought, and naturally I kept a mag loaded for home defense, but having only one magazine at the time, I unloaded them every time I went to the range so I could use the magazine for target ammo, then when I got home I re-loaded the HST’s back into the magazine. I can try to upload pics of the worst looking ones if it helps. I examined a completely untouched box of 124 grain HST’s and didn’t see any denting at all like what I see on the rounds in question. I loaded them by hand, so I don’t see how I could have dented them, unless it was the rim of the next round to be loaded in, pushing too hard on the round below. I have 6 magazines now and keep 2 of them dedicated to home defense, so they never have to be loaded and unloaded in such a manner when I go to the range, but because of the ammo shortage I’ve finally come back to this box and noticed the small imperfections. Thank you in advance for any feedback! I’ve been coming here for all of your expertise even before I bought my first handgun! Pistol is a gen 4 glock 19.
