This is on a Springfield Armory SAR 4800, Brazilian-made (Imbel?) rifle that I got several years ago and a few years later put a DSA trigger, sear, charging handle kit, etc. on it to get rid of the thumbhole stock and legally transform it into a proper-looking FAL.
Over the years it's been pretty accurate, dead reliable and has digested all types of commercial hunting .308 (not high velocity) and surplus NATO ammo without any problem.
Today I was shooting some good 1987 vintage German NATO ammo and also Federal Vital Shok 150 gr. (Barnes Triple Shock) to get ready for a pig hunt.
The NATO rounds worked fine, as usual, but when I tried the Federal .308 I fired 4 rounds as normal and then got a double shot. The next two shots cycled as normal to finish the magazine. Thinking the double was just an aberration out of the thousands of rounds I've fired through this rifle, I loaded another mag of the Federal and got a slam fire when I released the bolt.
Now I admit I've been shooting the hell out of this rifle lately, and haven't cleaned it religiously as I probably should have, but this seems like a bigger problem than a thorough cleaning would solve.
Any ideas what could cause this problem before I ship it to Springfield or DSA for repairs?
Thanks!
