A friend of mine wants me to look at his Colt 1911A1 he says it feeds all ammo perfectly except Wolf where he gets FTE, the empty stays in the chamber. Could there be a differance in the brass to cause this. Any ideas?
The simple solution is to have your friend stop shooting Wolf ammo...not every 1911 will shoot every ammo...that said, is this new manufacture Wolf, or the older stuff with the red laquer around the bullet/case to seal it?
Wolf no longer uses lacquer, and hasn't for a few years now.
Some guns don't like some ammo. There really isn't anything specific about wolf IMO that would cause it. All of my guns will reliable shoot wolf, although I don't use it anymore since I started reloading.
About 20 years ago, I had a S&W 645 that had consistent failures-to-eject when shooting one particular lot of Remington ammo. It functioned correctly with other ammo, but not with the current lot of Remington ammo we had to carry on duty.
Our department armorer hand-fit and installed a new extractor on the pistol, and it worked fine. He said it looked like the original extractor claw was within specification, but reached a minimum distance onto the cartridge rim; the lot of Remington ammo had rims that were at the minimum end of their specifications. Those two factors together probably caused the failures-to-eject.
Well I l cleaned the Colt series 70 well and tweaked the extractor a little and polished the chamber and went thru a 1/2 box of Wolf with no malfunction at all. I will try it again tomorrow and see what happens.
Give it a little more oil, I have seen countless times where someone cleans there gun and lubes it after getting it back together, goes out shooting and has all kinds of failures, and they think they have have gun problems, or ammo problems, then you give a squirt of oil and it runs like a champ.
Extractor tension is critical and steel cased ammo may not extract well if it's marginal. Something about more chamber friction compared to brass.
I put 1200 rounds of Wolf thru my 9mm M1991 last spring and had a couple of failures to extract at that point. Quick tweak of the extractor got me thru the course (another 600 rounds) with no further problems.
