New smokeless muzzleloaders are available from more places than just mcworters. Hankins, etc. I had a local gunsmith convince me a couple years ago to build one. I resisted on them due to the price, and that was the dumbest thing I ever did. I would find him several times at the range testing new builds, 2-4 at a time. In the meantime I was chasing my savage smokeless all over with it’s never failing to shoot a good group etc. the breaking point was watching him shoot a group with the one he built to light load for his dad. Three shots in a hole. I said fine I want one. Found a Remington 700, handed it to him and told him have at it. It’s my best shooting gun! Last year I hunted in the rain so I went to the range to empty it. The 100 yard range was occupied so I scooted down to the 200-300 yard range and tested the accuracy of my Leupold’s CDS. Dead on at 200 with first shot. The 300 was dead nuts on as well. The three shot 300yard group freaked out the other guy shooting his high powered rifle. We walked down range and those 3 were about 1 1/4” center to center, two were touching. I called and told him, he laughed and asked if I was having a bad shooting day, that I needed to practice, that the gun would shoot better than that. I believe him. I was shooting off bipods. I think off a solid rest and watching the wind, it just plain works. No stupid sabots, etc. A 300 grain bullet going 2800fps works pretty good….
