These are my 2 Magnum Research BFR Revolvers. One is in .45-70, and the other is in .500 S&W Magnum. Not Rugers mind you, but they are very similar to the Ruger design. I really like the counterbored chambers. My Ruger Super Blackhawk has them, but it was purchased back in 1973. I wish Ruger would go back to that. It makes for a nice clean looking gun. I also like the fact the barrel isn't set back in the frame too far. The handloads pictured with the .45-70 are loaded with 552 Gr. Gas Check Cast Bullets. Recoil isn't too bad because of the guns weight, (4 1/2 pounds). Bill T.
This is my Marlin .45-70 Guide Gun. It makes a nice companion piece to the .45-70 BFR. I like pistol / rifle combo guns. I've got a Winchester Trapper in .45 Colt to go along with my 2 Ruger Blackhawk .45's, and a Marlin 39A to go with my Ruger Stainless Single Six Convertable.
