I own a Blk. Dia. XR SS Express HDGN. Great ML. accurate & i gave $296.97 before taxes. I started off using Hornady sabots & their 300gr. .452 pistol bullets. Tight is an under statement! Need a good range rod to push them down the bore. I have went to .451 size an it helped alot to ease the loading. I shoot 80gr. of 3f at this time. Its left over from my T/C Hawken & Renegade days. When its gone i will use the Pyrodex i bought.
