The other day I went to the range and shot a couple AR guns and also broke in my new PSA PA-10 replacement barrel. I put a BA Hanson barrel on and a adjustables gas block and really tamed it down a lot. It was way over gassed from the manufacturer. After which I went to my long slide 1911 in 10mm. When I packed up my ammo I grabbed a box of Armscor 10 mil and a box of Sig 10 mil. First I tried the Armscor ammo. It was purchased back when Ammo was almost non existent. I mean when shelf's were bare. You know when I am referring to. Anyway it wouldn't chamber a round. I could slam the back of the slide and get it to go in but not right by any means. I know it wasn't the gun because it has never done that before. Always a reliable shooter. I went to the Sig ammo and it went through 50 rounds without a hitch.
After we were done shooting it we got to inspecting the ammo from Armscor. It looked like the projectile was just a little bigger than the case. It had a pronounced ring around the case at the bottom of the bullet. It really stuck out on one side. Almost as if the bullet itself was out of spec but they put it in anyway. I even replace the recoil spring to a 22 lb. spring thinking the spring had lost tension over the last 6 or 7 years. The original recoil spring rate is 18.5 lbs. and the slide was way to easy to work for a 10mm. It felt like a 380. The gun ran perfect with the heavier spring but it still wouldn't chamber those Armscor rounds. The ammo is the only reason we could come up with. Because I pooped of a couple of SD rounds I have for it as well with no problems. Have anybody else ran into this issue with stored ammo?
