Just got into muzzleloading last year so forgive me for the simplistic question. At the end of last season I took a shot on a deer and when I tried to reload I couldn't get the sabot bullet down the barrel to re-seat. The first load with a clean barrel went right in with out a problem but after the shot the sabot probably went about 1/2 way down the barrel before it would go any further. After the first shot I did nothing to the barrel besides putting in the new charge and bullet. What did I do wrong and how can I avoid the problem in the future? Clean? Lube?
