The Sig p322 is very sensitive to correctly loading the magazines. Mine sometimes fails to load the 3rd round in the mag and I've had more than a few misfires most of those rds went off if tried again in the Sig or another rimfire. Further investigation showed a build up of crud (powder residue and bullet lube) on the bolt & barrel face as well as in the firing pin hole in the bolt, once cleaned out much less misfires. I am sure the fouling is from the Fed Automatch I've been shooting the Super X 40 gr plated stuff has no.lube on it but gave misfires. I will try the super X again now the bolt is clean. When it works it's fabulous but the reliability of mine right now is dubious. What Mac S said makes alot of sense to me...mb
