I'll have to check that video later, just got back from the range and ice cream :)
We dumped about 200 or so rounds of winchester through it, just two snags both of which were dud rounds so not the gun's fault. The ammo has about the same ratio in the 10/22 and 1911 with conversion. Thank god for 22, because we just about killed that bulk box in an hour, plus all the 223 and a bunch of 9 and 45. Amazing how much ammo you can go through in an hour with three people on two ports.
I've decided that AR's are cheap to buy, expensive to shoot. Not because it's so costly per round, but because it's way too easy to burn through a lot. My current plan is to only bring a few mags worth loaded up and no extra, it's easier than counting on self control
Unrelated to the 22 conversion, but we fired about 120 rounds of mixed 223/5.56 without issues with ignition. PMC, Winchester white box, and Prvi M193 and 69grn match. The trigger felt great, best few dollars I've spent on a gun upgrade ever.
Sooo, to recap, my "reliable" list so far:
Winchester Xpert HV (non plated)
Blazer
Aguila Super
Remington Subsonics (needs more testing to be sure, but track record's decent)
I really want to pin down why the remington stuff went from just fine to problems, Magazine angle? Spring tension? Lube amount/location? Just plain tolerance variations in the ammo?
An informal accuracy test with the scope at 12x resulted in a sub 3" group with the Winchester. A good bit of the wiggle was me, ignoring the shots called as lousy it was more of a 2" group. this is 25 yards. Not excellent, but prone or benched rather than just resting my elbows on the port's shelf would probably cut another half inch off just on wiggle factor so that's more than good enough for me, particularly with bulk ammo. I got a roughly 2.5" group offhand with 223, but took a lot longer and put more care into each shot. No internet bs for me, lol, that translates into about a 10" group at 100 yards offhand with magnification, I'll take it.
