I'll do the Remington on Thursday, because today and tomorrow are supposed to be much like Monday was: 90°F/90% humidity, and that's indoor shooting weather as far as I'm concerned. The humidity down there on the banks of Eagle Creek will take the starch right out of you.
The American Eagle 10mm has a reputation for being ".40 S&W power level", which isn't entirely true, as it's 50-100fps hotter than pretty much any 180gr .40 I've chrono'ed, but it is definitely the mildest 10mm load I've yet clocked.
It's also the most consistent. Freakily consistent...
Here's the better of the two strings:
There was one failure to fire on round number forty-six of the day (#1,376 of the test). The round went off on the second try. It looks a little like the gun may have been slightly out of battery, but I could not make it replicate the situation in dry fire? Besides...
This makes 1380 rounds since the Glock 20 was cleaned or lubricated, with four failures to feed (#401, #454, #1,213, #1,297) and four failures to fire (#598, #1,016, #1,029, #1,376). 620 rounds to go.
