As mentioned, swab the barrel every shot, that's certainly the condition your rifle is going to be in during the hunt. I've tried many of the powders and thus far the APP Shockey's Gold is easily the cleanest I've seen.
if you can find it. Everybody carries 777 now even Wal-Mart, but Shocky Gold, hard to get in my area. I have about 1/10 lb left, did NOT dare to start hunting season with it. Just can't find it anywhere in my area, so will stay with 777 and the crud ring, but 777 is accurate and powerful in my guns and the crud ring is just anissue, not a big deal.
