I hit 3000 rounds today and I wanted to post an update given the few issues I was having.
For the first 800 rounds out of the gun, I used new Wilson 47s (7 rounders) and had two failures to feed/chamber on the first round in the mag. I don't know if it was the same mag. All ammo was 230 gr CCI Blazer Brass.
For the next 1200 rounds, I used new CMC Powermags (8 rounders) and had two breech over base stoppages with 230 gr Speer Gold Dot. Ammo shot was 50 rounds of 230 gr Federal HST, 50 rounds of 230 gr Speer Gold Dot, and 1100 rounds of CCI Blazer Brass.
For the last 1000 rounds, I used the CMC Powermags with Tripp Super 7 kits installed. I expected good results as I have had no problems with this type of mag in the past. I had no stoppages of any kind. Ammo shot was 50 rounds of 230 gr Federal HST, 50 rounds of 230 gr Speer Gold Dot, and 900 rounds of CCI Blazer Brass.
