I've tried it different ways and wasted 100 primers and bullets, I'll think move along.
The Unique performed quite well 4.0 produced 3" at 2 yds of off of the rest but had 4 stoppages, stove pipe, and FTF, just a little under powered. 4.2 did nearly as well without the stoppages. Very low recoil, almost like a pop gun.
