So myself & a buddy head out this morning with a few pieces of hardware to plink. I as well took my chronograph to test some new cast boolit loads for a 1911. This particular 1911 is a S&W Government Model in stainless and is one of my favorites. I bought it used a couple of years ago in a pawn shop and have since put somewhere between 500-700 rounds through it, 99% of which are my own mild reloads and cast boolits.
This morning after setting up the chronograph and target I took my first shot from a rest and the thing ran away full auto for five rounds. Somebody up there was looking out for me because by some miracle I DID NOT manage to hit the chronograph as this thing went Rambo on me. I subsequently loaded one round, removed the magazine and fired it six times with no hammer drop on cycling. I went on to shoot another 50-75 rounds normally with no issues. I pulled it down and cleaned it after we got back and found nothing out of the ordinary although I didn't strip the action, I'm going to leave that to Borks guns here in Cody as Tony Bork specializes in 1911's and I don't want to mistakenly "fix" it and not know what I did. Either that or have to take it to him in a baggie because I'm not smart enough to put it back together.
When I say "mild" loads I'm talking middle of the road not light and not maxed out using either 164 gr LRNFP's or 228 gr LRN's, so it's not like the slide is failing to come back far enough. This thing is super dependable and about the only time I've stovepiped or had a failure to go into battery was when I was shooting more than a hundred rounds loaded with TrailBoss. This morning the powder was Universal and the gun was clean although it had been carried in a dusty environment the week before but not fired.
Anybody got any ideas what may have caused this or had a similar experience?
