I've owned a Traditions Yukon 50 cal. and up to this week I' be lucky to hit a stop sign size target at 100 yards. After much research and very confusing advise from every one I talked to, I have resolved the problem. When I bought the gun it came with a dvd which covered all styles of muzzle loaders. I even talked to Traditions personally who told me not to use power belts, (sorry to you power belt buffs, they will not shoot straight in this gun) I started all over read the owners manual again and it reccamended 2 50gr. pellets with 200 gr. sabots, the same pellets with 250gr. and the 300 gr. sabots. I went to walmart and they had the t/c shock wave in mag express sabots. I bought 200gr. and 250gr. started at 25yards ran a dry patch in and out to remove grease, and fired a primer at the ground, then loaded 2 50 gr. pellets with the 250gr. sabot. and fired at the target. Then repeated with the dry patch, then fired a primer at the ground to remove any loose material then loaded again, and with great amazement fired into the same hole on the target. whoo hoo. finally now I can set the scope for the first time. repeated the same steps 4 more times with the same great results. had to clean breach at this point. the 200 gr. sabot had great results too, but the hit in a different place, so to all who have lost heart try a different bullet, make sure the bore is dry and grease free, and after shooting clean gun well.
