several years ago my gunsmith was making a small ring mauser into a 35 remington, as we talked i ask if he would rechamber a 10" bull barrel in 357 mag. into a 35 rem. and as the twist is 1-16 for the 357 contender barrel and the same for the 35 rem,and said he would like to try it. well the rechambering went smoothly and the extractor adjustment did also. with a 2x burris and 150gr and 200gr factory loads going into 1-1-5 inch groups at 50yds, its now my carry gun while riding my atv. i have not reloaded for it as i have about ten boxes of factory ammo. eastbank.
