I have had a lot of success with a .50 Knight Wolverine II (now the Bighorn)385 Hornady Great Plains, and 100 grains of Triple Seven. Ignited by a no. 11 cap. The key to accuracy with my rifle is to foul the barrel first with a normal load. And swab the barrel with a spit patch between shots. It is really accurate and I have killed a lot of animals with it. I also removed the rear sights and mounted a williams peep sight in the rear scope holes. I use a little rem oil in the barrel when I store it over the winter but stay completely away from cleaning the gun with any petroleum based solvent. In fact, I use Simple Green to clean my entire gun and have never had a problem with rust, powder residue, or lead fouling in the past 10 years. I can tell you a horror story of cleaning my rifle with regular Hoppes no. 9 and completely missing a BC blacktail at 30 yards. I couldn't hit a 4X4 target until I burned all the solvent out of the gun which took about 4 shots. That sucked.
