My bolt and money order are on the way via USPS.
I have long contemplated simply buying a break-action muzzleloader to allow me to shoot better powders (777, Blackhorn) with 209 primers, as the Remington action can be a bit of a PITA to clean at 10:30 PM after an all-day hunt and a late-hour kill. But the darned thing is so accurate that I never do. Honestly, three 295-grain Powerbelt Aerotips in 5/8" @ 100 yards is nothing to sneeze at from a muzzleloader IMO.
So this modification looks to be my answer. I've seen a few others, including one that utilizes primed .32 ACP cases, but this one, judging by the pics, looks like it is simply part of the rifle as it came from Remington. It looks that good.
I think I'm going to start looking for a walnut or laminated stock to put that barreled action in. Instead of simply being my "blackpowder season" rifle, it may become my all-season rifle if it looks as good as it should shoot.
