I'm having full ignition issues with my 45cal CVA Paramount and was hoping to get some advice. I'm almost 80 percent sure it has to do with the Blackhorn powder or my measuring abilities. This issue has been persistent since this first shot out of the box. I'm on my 10th shot with the new rifle. I'm measuring out 105gr of Blackhorn by weight to equal a 150gr volume charge (per the owners manual) on a Hornady G3-1500 scale. I'm using the factory included 285gr Powerbelt ELR bullets and CCI Large Rifle #200 primers. When I pour my powder into a Magnum charge tube, the powder sits about even with the 120 volume line. The rifle shoots consistent, holding my same zero after every outing, but SUPER dirty after 1 single shot. The breech plug is charcoal black with crusty build up that I have to scrape off with a pick and barely can scrub off the rest with solvent. The barrel is the same charcoal black coated. For sure not measuring up to the no swab hype in between shots. When I shot 777, it burned much cleaner in other rifles I have compared to Blackhorn. I do use the Blackhorn branded cleaning solvent to clean the rifle. I so far have tried: new different lot number of primers, different new container of Blackhorn, raised and lowered the amount of powder charge, changed the tightness I put on the breechplug, fired with and without oiling the barrel after cleaning, marked my ramrod for consistent loading, and changed the conditions I was shooting in (cold, hot, humid). It has shot the exact same every time. Any advice? What am I doing wrong!? I'm about to lose my cool and go back to using 777.....
