You add a little weight to cut the recoil.We developed cartridge in
a Ruger 77 bolt action, using it as single shot.Had to narrow up back bridge to lengthen port, and changed bolt stop.We also chambered P-17 Enfield also.Two friends are rechambering #1's.We tested it with 1900
rounds in 3 years, using two barrel lengths.It will work in good O/U
and double rifles also.We are getting thing together to make a run of
factory brass.Have place to get reamers and loading dies.Anyone
interested let me know.
