Here's Binky-Roo's (as I've come to call this rifle) 100-yard group with fire-formers. Looks like a keeper!
Attachment 134605
A little over 2", which for a thrown-together fire-former and coarse open sights ain't bad. I don't know the velocity (didn't bother bringing the chrono today) other than for sure 5 grains of Unique gets it supersonic.
I also did a short range milk jug test with two alloys - same 5 grain charge for both:
Attachment 134606
Left bullet - water-quenched wheel weights; stopped in gallon milk jug #9 (that's right kids - NINE gallons of water! - the same as it took to stop my same-alloy .45ACP 230gr LFN). The nose compressed about 1/16" from pre-firing, but that's about it for deformation.
Right bullet - 20-1; stopped in gallon jug #3
I'm rapidly learning that, while I probably will do a lot of mild loads with it, the .32-20 is no pipsqueak. I DO think I'm going to hunt down some more serious sights for it. I seem to be too old for opens. . .
