I shot some 200 gr Shockwaves will the new Harvester 50/40 CrushRib Sabots out of my Knight DISC yesterday. This is the most accurate combination I have found for this muzzleloader to date and I have been shooting it for 6 years. I was shooting both 115 gr and 120 gr charges of Blackhorn using Federal 209A primers to ignite the charge. The three shot groups were between 1" to 1 3/4" at 100 yards. I did some shooting at a 15" X 15" target at 300 yards for grins and was hitting it. The question is have is how well to they actually work on deer? The plan would be to shot them behind the shoulder. Let me know your experiences good and bad.
