It will be a Mosin Repeater like this pictured 300WM with a Krieger barrel I built 6 years ago.
I have also converted Mosins to 7mmRM and 25 Krag Ackley that are repeaters.
The Mosins I converted to 45/70, 30-30, 45 Colt, and 223 are are single shot.
In October I will be hunting with a guy who is building a 270x54r right now. He has been hunting with Mosins for 51 years.
