I decided to share some results from today's range session with the board.
The targets below were shot by a 336 "G" gun and RCBS 30-180FN which I don't have the BHN for but they weighed 199 grains with the check applied. Sorry I don't have the BHN but the alloy was probably clip-on WW metal mixed with soft lead. The boolits probably weren't heat treated because they were easily scratched with my thumbnail. Sorry for all the guessing but this ammo had been stored for many moons. The powder charge was 16.5 grains of WC820 for approximately 1700 fps. The chronograph was not set up today but this load has been chronographed extensively in the past. After the first target I moved my sights a tiny bit to the right.
The thing that amazes me the most is that these rounds were assembled in WW 32-40 cases and these are my fireforming loads. It's real tempting to mount a scope on this fine old rifle and really do some serious load development. The range was 100 yards and the sight were Williams FP with a .050" aperture in the back and up front, a Lyman 17A with the 2.6 aperture.
