bad ammo!
bad, bad ammo! and cheap scope also. I went to the range intending to shoot 20 rounds each of 5 different types today... but it was 1 too hot and humid, 2 the nc star scope came loose again so i couldn't hit anything, 3 i got pissed at one of the ammo types, so i quit after 60 rounds and will try the other 2 types after i get a different scope on this thing. I started with PMC Bronze 147gr fmj-bt, they performed perfectly. Then i went to CBC Ball M80, out of 20 rounds only 3 fed automatically i think. i started with 2 ten round mags, loaded up, boom, click... ftf, reset rounds by slapping on leg, loaded up, boom, click... repeat. after doing 5 rounds that way i took the last 5 out and put them in one of the mags i had just used for the PMC, same story, had to load each one after a ftf. there was also one fte along the way. most of the ftf clicked on an empty chamber, a couple jammed with the round part way out of the mag. On the second 10 round mag it was the same story, except in this one i had one misfire. it shows a relatively light pin impression and would not extract with the charging handle, i had to pop the rear takedown pin to get it to clear... i would guess the bolt hadn't quite seated and the hammer was stuck against the back of the carrier after making light contact with the firing pin keeping the charging handle from pulling the carrier back... if the round had actually fired that might have been a mess. I did continue until the second mag was empty, double checking to be sure the bolt was fully home each time, it actually properly fed 2 rounds in a row at one point! Just to make sure it wasn't something with the gun i then went through 2 ten round mags of Brown Bear SP, by then the scope was loose so i was just kind of aiming for the backstop but cycled through both mags without a problem.
