I started patching a 405 grain Lee bullet with grooves. Before patching, I lubed it and ran it through a 0.452" sizer, then removed the lube before patching. Shot fine, but ended up getting a 0.452" mould to save a couple of steps. Starting with a 0.452 bullet, I've had good luck patching with 16 lb. paper (college ruled notebook paper) and I don't have to resize after patching, saving another step. I've used printer paper (20 lb.) but found I needed to size again and lost about 50% of the patches. As far as lube goes; some do, some don't. I use either Alox or Lyman moly stick lube. Leaning hard towards the Alox as I think it gives some degree of water proofing. Wet patches are about as useful as wet toilet paper. When rain threatens, I also place my extra shells in a rubber glove. Patching is not as hard as it appears and adds mystic right up there with two bat wings and an eye of a newt. Hmmm, maybe it's the newt eye that makes that big bullet so effective.
