I had an early vented 24" rifle model with the 1:20 twist before they went to 1:38 when so many were complaining about getting accuracy with lead bullets.
Mine had a very nice trigger, no creep and broke in the neighborhood of 3.5 to 4# in comparison to other triggers that claim that weight range (T/C Omega and the trigger in my AR).
I was attempting to get a friend's home-cast MaxiHunters to group out of it and I could not. Went with the .430 XTP 300 grain in the T/C Break-O-Way sabots and it would overlap bullet holes at 100 yards with a 3-9x40 scope on it. In retrospect, his bullets were atrocious! I should have tried some factory MaxiBall!! Shot my first muzzleloader deer with that rifle and was extremely happy with the XTPs. I eventually parted ways with my Scout and moved on to a ThunderHawk. This move was specifically because of the vented breech plug. One day I was shooting it at the range in windy conditions and a spark/ember from out of that damned plug blew back and burnt its way through my mustache and onto my lip. Took it home, cleaned it good, and put it on the rack for sale!!
I really wish someone would do a smokeless conversion on a Scout; doing away with the vented plug in the process and modifying the hammer for 209 primers and LR primer adapters. That would be a really cool smokeless!
