I finally found a can of BH209, I was at Bass Pro and they had one can. I still had some, but not enough for my son to practice much before his muzzleloader hunt in 3 weeks. I have a box of 300gr LR bullets from Arrowhead Rifles showing up tomorrow or Friday so he’ll get plenty of prone practice with the rifle this weekend. I guess we’ll see how much powder he can handle shooting prone.
