DD/BCM acting up after shooting steel cased ammo
Preface: My DD/BCM has NEVER had a malfunction in its ~3000rd career.
So I got a good deal on some Wolf Polyformance, cracked off 120 rounds of it yesterday, and not at a fast pace. Not a single malfunction.
Today I go to the range and decided to put some of my PMC bronze/IMI M193 ammo through it. 60 rounds, 4 FTE's.
I know Wolf is dirty, but damn, didn't think 120 rounds would cause it.
Anyone else have this problem? I guess I just proved that at least in my rifle, the gunk left in the chamber due to steel not expanding can really affect extraction.
