Just took my new .40 out for the first time today, got about a hundred rounds through it. I fired a box of remington 180 gr with no problem but when I switched to Blazer 165 gr aluminum I started geting some nose ups, so I switched to blazer 180 gr brass and about every 5th round was a nose up. Unfortunately it started to rain before I could switch back to remington. Has anyone else had problems with blazer brass? I kind of expected the aluminum to be tempermental.
