Reloader I consistantly get 3269 fps. over a Shooting Chrony using 76 gr. RL-25 and a 162 gr. Hornady from a 24" barrel out of my Mashburn. My case capacity is 90 gr. water or about 4 gr. over the 7 Weatherby. I only shoot 160 gr. +/- out of this gun and accuracy is consistantly .6" +/-. I am building another on a Rem 700 and will set it up for 175's; Sierra or Nosler. I intend to use Retumbo or H1000 if the gun will shoot that powder well and be done with it.
At 3269 I can reload the brass about 8-10 times before it work hardens in the neck to where I need to anneal it and instead I chunk it.
To me the Mashburh is effective, reasonably barreled (24"), light 8 lbs. +/-, and plenty powerful. What is not to like?
Warren Page was right. I bow to his superior wisdom.
