Reloading for Glock 19 9mm

[ronas]

Is the brass fired from a Glock 19 in 9mm expanded evenly when it is fired? Or is it expanded more in the area where the chamber is not supporting the brass?

I ask because I've read about the kabooms, which in most case seem to have been caused by double charge.

I shoot reloads only unless a class requires factory ammunition. I reload on a Dillon xl650 for a Beretta 92FS and I've never had any problems with my reloads, but I'm a little concerned about using them in a Glock. If the brass in not evenly expanded when fired from a glock chamber it would seem that resizing the brass would not achieve ideal results. That's just a guess.

Some Glock owners report seeing a "smiley" face mark or bulge near the case head. I guess that's where the case would be over the unsupported area of the chamber. Many others can't see anything visibly on the cases. I've never seen any strange marks or bulges on my fired G21 cases. I think in either case, if you properly resize them, and the assembled cartridges chamber fine you are good to go. There's a theory from some who are paranoid about reloading for Glocks that the brass is expanded and weakened more because of their loose chambers and thus the cases are not safe to reload. Well, they may actually weaken or expand more, and that may decrease their service life, but the result will be the same as all other straight walled pistol cases when they have seen their last day. They will most likely split near the case mouths. Many rifle cases are a different story all together, however. Considering the countless people who reload for Glocks, and the number of ranges who rent Glocks and have their reloads fired through them, I don't feel it is much of an issue IMO.

Your once fired brass from your 19 is more than likely not safe to reload, due to the loose chambering of the Glock design. I strongly suggest you send all of your spent brass to me, Immediately.

The resizing die should take care of the "belly" if any. To mitigate any remote chance of a KB is not to run the "Max Loads" and also stay away from Lead (unjacketed) bullets. If you're going to shoot lead, then check the bore and throat for lead buildup frequently. It's this lead buildup that spikes the pressure leading to some KB's. Glock's polygonal rifling with it's smooth lands seems to let the softer lead bullet slide/skid into the rifling which contributes to the lead buildup more than conventional rifling. Let unchecked, it can reduce the bore diameter enough to spike pressures.

ive not seen any of the so called "glocking" on 9mm

the 40 s&w is the culpret

Semi-auto pistol brass tends to expand more on one side than the other. This is due to generous chamber dimensions and the extractor placing tension from the right to force the case against the left side of the chamber.
