Welcome from SE Indiana and the addiction! I’ve had my Optima .50 cal for approximately 20 years and I love it. When I had my TC Hawkins .50 cal and my apex .50, I used bore butter and I concur with rangerod. In the heat it will soften and melt. In the winter, it seems to harden. That being said, everyone has a different means of cleaning and lubing their ml. I use Hoppes #9 to clean mine and a good quality gun oil to lube it and storage. Before I start shooting and before deer season, I will run a couple dry patches to remove any excess residue prior to loading it. There’s a whole array of quality muzzleloaders out there. Honestly, I think the choice is going to depend on what you’re comfortable with spending. Just do your due diligence in research and make your best decision based on what you’ve found out. There’s a lot of cva fans here, as well as knight, TC, Remington and the like. It all comes down to money and features you want. Best of luck and have fun in your endeavors.
