Rapid Fire

BattleRifleG3 · 01-07-2003, 03:03 PM

Last weekend I rediscovered a bunch of Chilean crap ammo that I thoutht I'd gotten rid of. So I loaded up a bunch of mags, oiled the ammo and mags (this stuff had a tendency not to feed), and fired off a hundred rounds as fast as I could (which wasn't as fast as I would have were the temperature not extremely cold and had I not had to charge it again for every misfire). Well, towards the end I had a problem where it would take two hands to charge it and I had to brace the buttstock on my leg. When I finally ran out, the barrel had turned grey, and when I licked my finger and touched it, it was like touching a hot iron or a freshly machined piece of steel. Kind of rewarding, but I'm hoping I didn't do it wrong. I locked the bolt back to let it cool, and when it did, it moved as smoothly as ever. Also leaned it against the back of the forearm, not the tip of the barrel, as I didn't want to put any weight on it.

Any thoughts as to the wisdom of doing all this?

The part about leaning it with the weight off the barrel makes sense to me. Don't know about the problem with the action or bolt though dude.....

I've read articles before about cooling down after rapid fire & seems to me you did everything by the book.

Military grade weapons are designed to be operated when hot - think of every trooper who's been in a firefight! A hundred rounds ain't that much in those circumstances.
Your tolerances might be a little tight, and with heat something expanded and got tight. A few hundred more rounds ought to loosen her up.

We tend to "baby" our weapons - understandable as we've paid good money for 'em. They're designed to go through he!! though.

My rifle is a Centurion 99 on an FA-91 aluminum receiver. All the parts that lock together are military, but being as aluminum has a lower melting point than steel, I wonder if that part of the system may be an area of concern. However, the handguard wasn't even warm to the touch (it's the wide one with the aluminum shield inside). I just cleaned the beast yesterday, man did the gunk flow! I think I'll be cleaning it again, as I only used oil and a toothbrush this time but in the past have used brake parts cleaner.

I do that with the maadi, but with about 50 rnds and it gets really hot and takes more than 20 min to cool off.

I still haven't done that to my G3, like big dog said, I still baby mine, but some day I'll do it just to know what happens.
