It was my pleasure to shoot a borrowed Danish Rolling Block in 45/90 loaded to 45/70 velocities in a Black Powder cartridge match out to 600 yards. 510 gr Postell bullets, no gas check, and a hardy load of Goex FFg. I had a number of fellows coaching me on loads, sight settings, and the intricacies of obtaining the much needed small groups to be successful. Most were shooting 45/70 as the 45/90 case was too much. I had a respectable showing with a new found appreciation for the 45/70.
