This is a bit of a mess but might help someone
These were bought from midway as pulled / rejects
I only loaded the ones that seemed pretty good. Didnt measure them though.
They appear to be 70gn GMX which does NOT have the polymer tip (there seems to be some misleading/contradictory Hornady info on this)
.224 diameter
Random range pickup brass trimmed to 1.750"
No crimp
2.250" COAL
22.5gn H335
1:7 AR w/ 16" barrel
Went through 6 rounds and only got one chrono result: 2645 fps
This is within 40 fps of the predicted speed from a very similar Barnes TSX BT bullet (Barnes data) so I think things are looking normal
My chrony setup is modified with an LED and has an unknown history but I am pretty confident in it
Anyways that is all
