Guys, In the batches of thousands of 40, and mostly 10mm Ive loaded, ive become more and more in tune with the Glock Smile, and the "Bulge" that causes the smile, and etc.
I do not use a "bulge buster" or push through resizer, so I always get my cases back to specification so that they fit loosely in my chambers. Most of my loads are A) not maximum pressure stuff and B) fired from an alpha wolf barrel where there is better chamber support, so bulging and the subsequent Glock Smile are a bit of a rarity for me, and the once fired brass from my firearms. Also since ive used a lanolin based case lubricant, ive noticed an even greater decrease in the smiles occurrences (possibly a misnomer, im not sure)
With all this being said, they (smiles) do happen every once in a great while and I usually catch them. My question for the greater population here is, how dangerous are "Glock Smiles" and what is the liklihood of a case head separation or KB due to these. Of an inspected 500 rounds, i discovered 4 that had the "smile".
I have another 1000 to check over.
10mm loaded with 9gr of longshot under 180gr Zero JHP for about 1,200 fps. and a book estimated 30,000 psi.
Chuck all the smiles?
FWIW, Longshot is an amazing 10mm powder because it gets the velocity up to where it should be for the caliber, and it doesnt bulge the cases for me. Its the only powder I can get 10mm Norma class performance out of that bulges the brass the least, if at all (Power pistol, and Blue Dot are good ones, but I get greater case bulges, possibly indicating higher pressure)
