I frequent the range - maybe going two to three times a month. I pick up much of the brass I see. I'll never pass over the chance to get 45 Auto brass. I have been collecting it for at least 13 years.
So, of course, I have quite a variety of 45 Auto fired from a variety of firearms. This past year I got into the affordable Tisas 1911's, picking up fou, each in 45 Auto.
Experimenting with this range pickup brass I'd have an occasional hiccup with my new firearms. A failure to feed here, a dented case mouth there. I was feeling the 1911 is a picky weapon. Then, a couple months ago, I reloaded a box of 100 rounds. I thought the brass was already sized, but was not 100% certain, so I full length sized the brass again just in case. They did not require much force on my press so I became certain I sized them twice. No harm, no foul.
I shot that box of reloads and they worked perfect! It was a treat taking out a couple firearms and having no issues during a range trip. Preparing for the next range trip, I full length sized each 45 Auto case twice again. And again, I got excellent performance in several firearms. So, for the past couple months I have sized my brass for for my semi-autos twice and all my weapons have run fantastic. This is using brass that is mismatched, and probably been fired by me a mix of half a dozen times to a dozen times. (I used to have an SR45 in 45 Auto)
Anyway, has anyone else had a similar experience?
