2" 500 Jeffrey wildcat

[triggerman]

looking at making a 510 wildcat out of a Ruger M77 7mm RSAUM
i am looking at taking a pac-nor barrel and basiclly short chambeoring a 500 Jeffrey to 2 inchesi would be looking art using bullet weights from 500 to 750 BMG

Can you open the bolt face enough on that Ruger to take the Jeff's head size?

i plan on rebating the rim
i also think I'm going to make it 2 1/4" with front ignition system

Late to the party ... I don't get here very often ... but Bertram brass in Australia produces brass for a shortened 50cal. Case length is 2.1", case rim size is 416Rigby, case head is either 500Jeff or 505Gibbs dimensions (need to check), 20deg shoulder. He's used it as a subsonic 50cal project with a 750gr projectile. Might be worth inquiring with them. I'm exploring its potential for pushing a 535gr at 2150fps from a Ruger S/A as a compact big bore rifle.
Cheers...
