If you have any.. and get a chance, try that same thing with 2f black powder. I used to shoot a lot of 3f, but I have convinced myself that I now get better accuracy when shooting lighter loads, with 2f powder. Conicals, I still like 3f. But if you have a little 2f, give that a try. Nice shooting with that 105 grains. That would be a real bread and butter load.
