I've never shot any Wolf gold so can't say what it might be as far as quality, but I've seen the OAL vary widely amongst Tulammo, Federal, American Eagle, PMC, Perfecta and others that I've shot. I had a slight burr on a barrel that would catch on a longer round but feed the shorter ones fine, took a bit of work tracking it down but noticed that it would only jam on the round that was feeding from the left side of the magazine. Bit of work with a dremel and all's good.
What sort of extraction problem were you having with the BM lower and the PSA upper?
well, a round fired and the empty casing just never made it out of the chamber. it was still pointed straight, not sticking out the side of the action.
My rage does not allow Tulammo. They tell me it has a steel core that will tear up the wall. I have seen too many people curse it, including someone at one of the board shoots. I have also read some bad reviews on it so I stay away from it. Wolf is supposed to be a better alternative if you are looking for cheap steel cased ammo and when I saw brass cased Wolf Gold, I thought it would be even better. It has fired pretty well for me so far, just a few malfunctions in my Bushy.
Oh yea, I had what I think was a total fluke. I put my rifles back to their original configuration and was shooting my "trouble free" PSA rifle. I fired about 3 rounds and CLICK. I pulled the charging handle back, ejected the shell and CLICK again. I thought there was something wrong with the firing pin, so I removed the magazine pulled the charging handle back again, ejecting the round that did not fire. I took the upper off again and went to take the bolt carrier out and the charging handle would not budge. I want to play with it too much without making the range aware so I asked for some help. No one could move the charging handle. We ended up having to pry the bolt open with a copper cleaning rod. When everything was apart, we discovered a bad primer had somehow broken off and jammed between the bolt and chamber. I am hoping that was just a case of bad ammo. I was firing some M193, "Made in Malaysia" ammo, dated 1982. I have had no other problems with this ammo and have read good reports from others online that used it before also, but I guess everyone is entitled to a bad round once and a while.
