On round number thirty-three of the day (#1,413 of the test) there was a failure-to-feed malfunction absolutely identical to the ones on the last two range outings with this ammo: Round was nose-up with the cartridge rim just barely not under the extractor claw. A slap of the floorplate and the slide went into battery normally.
Like both previous times, it happened in one of the first few rounds in the magazine and this time I took note of the mag number (#3). I wish I'd done that before, because it nags at me that these malfunctions have three things in common:
- All with the Remington UMC ammo.
- All with a relatively full magazine.
- All since I purchased magazines #3 and #4.
I fired the first box at the five yard line and then moved the target back to ten. It was hot, I was cranky, my glasses were fogging, I'd already fired fifty rounds of 10mm, and all those other excuses...
401, #454, #1,213, #1,297, #1,413) and four failures to fire (#598, #1,016, #1,029, #1,376). 520 rounds to go.
