Take a look at these, just ordered one for 9mm to up my game, before I lose fingers.
I use a similar one, I happen to get mine from Dawson Precision:Take a look at these, just ordered one for 9mm to up my game, before I lose fingers.

Or for 9mm you could get this Lyman gauge. It's what I use for my loaded rounds. This is a loaded .380 that got through my LNL-AP undetected.

All my loaded rounds go through this. As you can see you can also compare round to round because all eight holes are the same caliber.
My Grandson recently found a 9 Makarov among my loaded rounds last week end.

This is a 9mm Makarov which isn't as obvious. I like these gauges and all my loaded 9mms goes through it. Really speeds things up.
That Armanov logo is a straight up copy of the PNW arms old logo. They are out of business now so I don't think they care, but it's identical!.
Agreed
Nothing ruins a 9mm PCC Match like a 9X18 MAK!

So, I'm just wondering here - the crimp dimensions seem a little too tight at .3785 to me.
If memory serves, Berry's is .356 rather than .355 and that makes it a little harder to get to .380 crimp.
I would suggest pulling a bullet to see if the case has engraved into the shank.
I'm not saying this is the cause. My first thought went to a round seating too high in the chamber. My second was an overcharge. I get really picky when I'm loading fine grain powders - it's easy to get a good deal of flux.
Just for giggles, I just went out and mic'd the crimps on a bunch of factory FMJ I have:
and then I dragged out:
- Winchester white box - .379
- UMC - .382
- Federal - .380
- Amerian Eagle - .381
I'm with Walkalong, and suggest the use of a case/cartridge gauge. I have both Wilson and Hornady.
- Rem Golden Sabre - .382
- Fed HST - .381
- Fed Hydra Shok - .381
- Win Ranger T - .380
Damn, I would have to pass on that !If you think 9mm is bad, you should have a .308 blow out on you...

I think in instances like this, outside of an OOB detonation... it has to be the brass. There are a number of things that can weaken brass, and there is always the unseen quantity of a bad lot or piece of brass.
Good info. I've always stayed in the .3785-.3790 range, BUT maybe its too tight. I will pull the 10 other rounds I have made and see what the bullet says, I was looking at the target I was shooting earlier this evening and there was a couple of holes that were not the normal 9mm hole. Thats either low powder or too tight crimp. My powder was dead nuts 5.45gr's so you are more than likely correct. I use Wilson and Dillon case gauges on every round. Like the Armanov blocks now too. Just always thought one-at-a-time was more proficient. Going to order one tonight. Thanks for the replySo, I'm just wondering here - the crimp dimensions seem a little too tight at .3785 to me.

I see you bought the Wilson. I prefer the Sheridan slotted gauge. You can see where the problem is.

I would like to see a cut of the case, as well as the maker. If you have a grinder you can do it like Charlie98.
