On another site I was reading a lot about SMLs and I thought I'd give it a shot! One of the cheapest ways to go was to have a .45-70 CVA Scout converted by reaming out the chamber area and threading it for a smokeless capable breech plug..I had mine done by Hankins Precision Rifles for $400. But before I jump ahead I had purchased the Scout in .45-70 and thought I'd check the accuracy before I sent it out. Being that I had a few other .45-70s I had plenty of ammo. No matter what I shot downrange they all shot MOA or better. I thought to myself, no way am I getting this rifle converted because it shoots too good. So I went and purchased another identical Scout and immediately sent the barrel out for the conversion. Once back, in a matter of two weeks, I had it out to the range after putting primers in the modules. Amazing! This rifle shoots every 250 - 300 gr bullet I tried out of it under MOA and at velocities up in the 2200-2400 fps with 55 gr of H4198. And the muzzle brake on it makes the recoil feel like shooting a .243 even though the rifle is fairly light weight. I know this isn't traditional muzzleloading but its just another advancement in its evolution. Believe me I still enjoy making white smoke from my inlines and traditionals. This is just another toy.
Left target below was shot with 250 gr SSTs and 300 gr Smackdowns. The right target was shot with 300 gr SSTs. All shots were with 55 gr of H4198 at 100 uds.
Now please don't go dumping smokeless powder in you CVA Apex or Optima, Wolf or Accura. It will blow up. This was a .45-70 barrel designed for shooting smokeless that was modified to accept a breech plug.
