I've had several Model 83's in 454 over the years - mostly 7.5" barrels. I used to load them to full velocity but got that out of my system years ago. I probably wouldn't own one now except I stumbled on a used premiere grade priced way lower than it should have been. It came with a 7.5" barrel and 2x Leupold scope. I had FA shorten it to 6" and replaced the scope with a RMR red dot. I don't shoot them as much as I used to and load milder loads now. One of these days I'll hunt with it...
