my sub 2000 eats these.. TNW Aero...no.
Curiosity got the better of me over Thanksgiving and I bought 100 of these. Small sample size, but no issues going thru a Girsan MC28 and an M&P 2.0. Fed and shot fine.
I hope Sumbro has addressed the case size issue. I found a bunch of range pickups that would not fit in the Loadmaster 19s shellplate as the extractor groove width was consistantly too narrow and too shallow.
