Re: Rem 700 firing pin keeps breaking
How much you dry fire, and for what reason, isn't the issue dude...you might want to back off the defensive about that. Not everyone is a natural at shooting, and some absolutely have to work out the head issues to become proficient. It's the same as anything else that requires hand/eye coordination. Shooting is a skill, it comes easily to some folks, some not. If it takes 1000 dry fires, or a million, it's all about how bad you want it. My kid is one of those naturals on the trigger...and he's one hell of a Linebacker too.
That said, the issue I see pertaining to YOUR topic that you queried here, is that you blindly expect a mechanical device to hold up after repeatedly "abusing" it to the tune of around 5,000 times, until it broke. I say "abuse" because a firing pin was ONLY MEANT to strike a primer to ignite it. Despite most folks having enough luck dry firing one, without much if any damage, it wasn't specifically designed to do that...and in my humble opinion certainly NOT THAT much.
A firing pin is a combination of hardened metal, speed, and tight tolerances...it's job is simply to light a primer, which is a cushioned blow not an abrupt hardened metal to hardened metal STOP as happens with a dry fire. Vibration and impact are the worst enemies of metal, especially hard metal. Clicking your rifle 5000 times put all the vibration and impact of one dry fire into that pin X 5000...it's no great surprise to me that it finally broke.
To quantify the number of dry fires a pin can "take" is an exercize in the rediculous...because at some point it's going to break; and that point is far beyond what common sense, and a little preventative thought, would have averted in the first place. What surprises me, and thus generated my response, is that you didn't get it after the first pin broke; and went on with two more firing pins completely oblivious to what might be going on.
I see a wonderful little snap cap on Midway for a measely 10 bucks that would have solved your problem with the first broken pin had you the ability to think for yourself. That you are willing to forgo the cost of one $10 snap cap in favor of the cost of three firing pins ($60+) based on blind allegience to the Dry Fire Gurus tells me (and to your vexation my 15 year old) that you have more money than brains.
Peace, out..........
