7mmWSM Loads

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?

Re: 7mmWSM Loads

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 . [img]/ubbthreads/images/graemlins/grin.gif[/img]

Re: 7mmWSM Loads

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.
