I'm looking for anyone who might have personal experience with a .50 cal. Knight Revolution. I'm hunting in 2 weeks here in Colorado and we have to use open sights, no sabots and no pellets. Looking for recommended bullets, powder type and loads. I tried sighting in yesterday for the first time with limited success. I tried American Pioneer Powder (Regular and J.S. Gold, which contrary to what I've read everywhere was no cleaner than Pyrodex ) with Powerbelts (348). 90-100 gr. powder and had no consistancy at all. Lucky to hit within a 10-inch circle @50 yds. and in all directions. I switched the powder to Goex Black Powder 90 gr. and no difference. I then swithed bullets to TC maxi-Hunter (lubed) 350 gr with 90 gr blackpowder and started to get some consistancy (within a 4-inch group) then after 3 hrs of shooting darkness stopped me. I did get a hold of a Knight Rep who happened to be at a local Store today, and they suggested trying 100 gr of 777 with TC maxi balls or Parker bullets in the 375 gr. range. I've been hunting with BP about 15 years and always learning more every year. I'd appreciate any feedback or suggestions anyone has!
