Muzzleloading rifles are hard on true rifle scopes, one should invest in a true muzzleloader scope designed for that purpose. I shoot 100 grs of Black Horn and 250 and now 290 gr bullets in the in-lines.
Thanks for your feedback, what game have you shot and at what distances?
I have a .50 caliber Traditions muzzleloader. I found it at a household auction.It's the Deerhunter model.1in66 twist.It will not stabilize the conicals but is accurate with the roundballs.I use loose powder(80 grains of 2f).Still working my way up from 50 grains to find the best accuracy.
When I use 80 grains of 2F in a 24 inch barrel the roundball passes through 3/8 particle board at 50 yards.I'm trying to determine the limit in terms of energy to kill a deer with this flintlock.A 1 in 66 twist limits me to roundballs.It will not stabilize conicals or PA Ballets.
