Dry Firing?

[kevinbear]

I'll say it again, those little plastic flouresent orange dry fire 22 cartridges made by Pachmayr are the way to go, I checked Midway and they were out of them but allowing backorders. If you think there expensive wait until start buying action parts. Under normal functioning of a rimfire the firing pin hits the soft metal rim of the case. Depending on the firearm this prevents one of two things from happening. On guns without close tolerences it prevents the fire pin from chiseling a dent into the chamber face displacing metal down into the chamber, nice. Brownells makes a tool to repair that problem. On rifles with close firing pin to chamber face tolerences that tolerence is maintained by a stop {ledge} on the pin and a coresponding stop inside the bolt. If you hammer two pieces of metal together {dry firing}long enough something is going to happen and it's not going to be good. There are mechanical variations of what I just described but the fact remains that longtime gunsmith friend of mine has repaired many .22's that ended up in his shop as a direct result of dry firing without snap caps. I would argue that even handguns that have magazine disconnectors will eventually have mechanical problems { the hammer still falls and is stopped abruptly} but probably after much more use. I've never examined one of the aformentioned rifles with a disconnector or stop so I cannot speak to that personally.

You better stop firing live rounds then, because it does the same thing, and fires bullets over top of the stuff from the previous rounds!!

Dry firing on empty cases dislodges burnt priming material into the barrel, I'm one of those clean barrel fanatics so this drives me crazy!

You laugh, but for a short period of time during the 80's some BR-50 guys were using compressed air to blow powder residue out of there barrels between shots! Bore scope photos published in Precision Shooting showing that most of the wear in a 22lr occurs in the bottom third of the barrel {when held horizontially}started that. The carbon settles there and works as an abrasive. Your right in that anything other than leaving your rifle locked up in the safe is going to wear on it but my point is why unnecessarily damage any mechanical device. See you at the gunshop, I'll be the one drinking coffee with the gunsmith and enjoying myself.

Stuff that gets into the barrel during each and every shot, and has bullets being fired over it with each and every shot, is not going to harm the barrel by sitting there doing nothing while you dry fire. Use a bit o' common.

It does mean you have to clean it again without having had the actual pleasure of shooting and hitting a target.

If you say so.

I don't think I'd ever sell a gun, actually.
