Tried Speer Lawman 115 and 147. Had random stovepipes and failures to feed. Some magazines would be great, some not. Most common issue is it does not want to load the first round on a new magazine when I press the bolt release. It jams the round every time into the top left corner of the barrel extension (and just barely bends out the case lip) esp if first round is on right side of the mag. After clearing it each time it would run the rest of the rounds without issue. I didn't think one of the rounds was bent at the case mouth badly at all so I loaded it into a separate mag, it chambered, fired, but took too hands on the charging handle to eject it. wont be doing that again.
It was 33 degrees out and the first trip with it so may need to get broken in. Or I need to be more particular in how I load the final round.
DDLES lower, 5" Tros, metalform magazines.
