    Any one played with this new caliber much? Any good loads out there. Just got one and want to get started. How about the 120 grain ballistic tips?

    nchunter ,
    Have had a Model 70 featherweight 7mm WSM for a year or so . Have tried 3 projectiles - 140gn Nosler BT , 139gn Hornady SST and 140gn Sierra Gameking . Nosler shoots the best , about 1.1 - 1.2 inches for 5 shots at 100 yds . Haven't played with seating depth yet . Hornady won't shoot at all , 2 inches plus .
    AR2213SC (H4831SC) and WXR (same as RL 22) shoot well at 66.5gns and 66.7 gns respectively . These loads give about 3190 and 3140fps . Not maximum but more accurate than hotter loads in my rifle . /ubbthreads/images/graemlins/grin.gif

    I've had a A-Bolt in 7WSM for a little over two years and have tried a bit of everything in it. My favorite powders have been WXR, RL-19 & 22 for the 140-150-160+ bullets. Have even loaded as much H870 as I could get packed into the case with a 175grn bullet seated and got a little over 2800fps. Have used 56.5grns Varget with 120grn bullets for nice accurate load or used W760-H414 for more velocity. Had a dandy load with 66.0grns RL-22 and a 160 Nosler Accubond at a hair over 3000fps. You sure have to push that long bullet way down into the case to make the Browning's magazine OAL of 2.860". I mostly use Fed. 215 primers except when using Varget or something.

    Looking through my data I see:

    120NBT-61.0grns W760 for 3153fps average
    120Vmax-56.5grns Varget for 3151 "
    120Vmax-69.0grns WMR for 3193 "
    120 Sie spt.-67.0grns H414 for 3427 "
    120 Amax-71.5grns VN560 for 3384 "

    I use more 139-140grn and up bullets than the 120's. You could probably do better with the 120's using one of the 4350's or RL-19 but I don't try many speed loads with a lighter bullet.
