Came home with the Model 7 Magnum in 300 SAUM with 22 inch bbl.The factory 180 Partitions went 3007 and just over 1 inch.anybody got a load that would aproximate that 180 factory load.if I can get anywhere close to that I will be a happy man.

You will probably need to wait until they sell the new Core-Lok bullets to reloaders.

180 Noslers all the way!!!!!!!!

unreal, i'm getting 2900 out of my 300saum bdl ss 24" using 66gr. rl-22. shoots great, but a bit slower than yours. might have to drop $30 and check out a box of factory 180's. for more info on loads, check out www.shortmags.org , dedicated to all things shortmag related. dh

Winchester uses W760 in their factory ammo and in many of the loads I've seen listed W760 is right up there in velocity.

gonna start out with the 180 sierra and A-2700,and see how things go from there.will wind up hunting with the noslers but there a little high to work up loads with.I have come to learn over the years that you can work a load with the same weight Sierra and pretty much change over to the Nosler.You may loose a couple tenths in your group but gain the world in killing performance.

I would suggest trying re-19 powder. The re-22 is a little slow for my taste.

Hope you don't mind me tackin' on another queston to your topic Mr. Big, but does anybody know which case has the longer neck-- the WSM or RSAUM??

the WSM case is longer but I dont know about the neck.

sscoyote,
The Remington neck is slightly longer at .3115" compaired to the Winchester at .2979". That's only .0136" difference.
Good shooting,
