Well I stopped by Bass Pro the other day, and got to talking with the guy there in the ML section. Told him my woes with my grouping. He thought my barrel may not be seasoned, so he sold me some deep cleaning stuff from TC, and some bore butter from them also. Anybody ever hear of this stuff? Suppose to make your barrel seasoned, whatever that means. Anyways I'm gonna give it a try. I deeped cleaned it already and the stuff is in the barrel now. Says you can also use it to lube your sabot's. Anybody here do that? I also picked up some Pyrodex RS/ FFG, Barnes SBT's in 245 grn., T/C XTP's in 240 grn., and some Hornaday SST's in 250 grn., also have on order some Maxiball, and Maxihunter. I've never shot loose powder before, so this will be a new experience. Any suggestions on powder charge? and what not to load too. I don't want to overcharge with powder. It is a CVA, hunterbolt magnum. I removed the scope and reinstalled the rear sight as suggested from F.Gander, and NC Hawkeye. Hope to get out next week after doing some improvements on the stock.
A lot of time you get wonderful information from store personal. Other times, they do not know what they are talking about. To season or not to season.. that is the question. I do not season my barrels. I used to but it lead to accuracy issues. So I cleaned the bore butter out of my barrel and never put it back in them.
Most books like from T/C will tell you not to lube your sabots. The sabot is the lube. Although some people do, and report good results with it. I do not.
For a powder charge try 90 grains of loose powder. And those bullets you purchased. I do not think you would need the bore butter in the barrel, but you do what you feel best. I would shoot on a clean barrel with 90 grains of Pyrodex and those 240 grain XTPs. Start at 50 yards, and be sure and swab the bore between shots... Good luck with your rifle.
