RE: How do you clean your casting molds?
Yes, you can get your sabots from MMP(Modern Muzzleloading Products). I shoot alot of cast bullets out of my ML. It is cheaper just to pour conicals, and shoot a bullet out of your ML. I pour a 525 grain bullet for my 50 caliber. When it hits a deer, it is **ll on earth. It is also quite effective on elk. I pour it out of an RCBS adjustable mold.
As far as your hollw points, I do not pour those. They are hard to pour. It is easier to pour solids, then HP the bullets on your case trimmer, or with a drill.
That 170 should work great with your 30-30. And keep shooting that black powder. Just be careful, you can get hooked real easily on that BP stuff. I shoot Silhoutte with my BP rifles, believe me you can shoot more than 5 times. Just mix up some cleaner, and put a few swabs through every few shots. Tom.
