Have a Guide Gun, and my only suggestion is one doesn't need to hot rod a 45-70. Shooting 405 grain slugs at 1,200 to 1,300 fps is fun, and they will down anything in north or south America. I decided to hop mine up to about 1,750 fps and it kills on both ends. Also the first unit I ever noticed torque when torching it off. Need to find someone willing to light off my remaining 85 rounds and I'll get back to a sensible load.
A buddy has a stainless version and both are surprisingly accurate.
