    Guys,

    I'm working on a combined 7WSM and 300WSM Cartridge Guide. This will also include the 7mm and 30 Cal WSM necked up from 270 WSM brass,used by Vince Bottomley and Alan Warner).

    I need your favorite accuracy loads. Please provide:

    Bullet weight and Mfg.
    Powder and load in grains
    Cartridge OAL
    Primer
    Brass Mfg.
    Velocity
    Comments on function, brass life, accuracy

    We are trying to cover both target and hunting uses of this cartridge, so please supply both types of loads, if you have them. In discussing a hunting load, you might want to comment on bullet performance on game.

    Please post your loads in this FORUM thread or email mailbox@6mmBR.com . Please put "WSM LOAD" in the title of your email. Be sure to identify which cartridge and brass you're using--I sure don't want to have 7WSM loads mistaken for 300WSM.

    7WSM

    175 Smk
    65.0 grains RL-25
    2.860" - AI magazine loading length
    Federal Gold Mdeal Match 215M
    Match prepped Winchester 7WSM brass
    2,900 fps from a 26" Kreiger 9 twist in Houston, 2,925 fps in Las Vegas at 2,200 alt.

    The Load shoots great. I used it as my 600 and 1,000 yard F-Class load until I got to Las Vegas in May, and it showed signed of being a tad bit too much pressure for my likeing.

    7WSM
    175 Smk
    66.3 grains H1000
    2.860" - AI magazine loading length
    Federal Gold Mdeal Match 215M
    Match prepped Winchester 7WSM brass
    2,875 fps from a 26" Kreiger 9 twist in Houston, 2,900 fps in Las Vegas at 2,200 alt.

    The Load shoots great. ES below 25, SD below 9. I switched to this load from the RL-25 for my 600 and 1,000 yard F-Class load after I got to Las Vegas in May, slighly slower, but less presure.

    I'll post additional loads in a few days when its not as crazy.....

    300WSM

    I have had 2 barrels in a Sleeved Rem 700 Heavy gun.
    Both liked exactly the same load

    Berger 190Gr VLD,Moly) jammed into the lands
    70gr 2213SC
    Fed 210M
    Norma Case,.330 Nk)
    the latest in a 1:10 Hart 30" gives me 3010-3020fps

    Fire forming load of 66gr 2213SC and 190 Berger's gave .250 groups consistently @ 100yds

    best group to date is 5 shots 2.7" @ 750yards

    1000yd 10shot best to date 9.77",only fired 4 targets @ 1000yds so far...)

    Cheers

    rifle is rem 700 alaskan ti 300WSM. Its favorite load is 60gr H380,168gr NosBT,Win brass and Fed215M primers.COAL is 2.860". I shot a whitetail buck @297yards and muley buck @200yards both one shot kills.The bullet totally exploded inside the whitetail his heart looked like someone cut it in half with a knife,I was unable to recover the bullet.The mule deers heart had similar results but the bullet exited the off side.I have also gotten lucky and shot 2 coyotes this year with this load one at 450yards and another at 482yards,big holes not good for pelts). At the bench this loads small grp was .298" and averaged .687" for the rest of the grps at 100 yards, velocity avg 2900fps @ 3865ft above sea level

    7mmWSM
    26 Inch Trueflite 9 twist .315 neck
    Winchester Brass
    Neck turned to .310 loaded with 3 thou tension
    Fed 215
    Moly 162gr A-Max
    63.8gr RL17
    COAL 3.015

    It took about 25 rounds with the moly projectiles before the velocities settled to 3185fps with this load. Am getting some cratering of the primer otherwise no other pressure signs even up to mid 3200's! Brass is at 5th reload, was full length sized after 3rd firing.
