7mm WSM Data Needed - Velocity & BC

[kwanjangnihm]

Guys,
What kind of velocities can be expected using the following bullets from a 26" barrel (avg to max). Is it even possible to use the longer bullets from Richard in the 7wsm?

Accubonds 140 & 160
SMK 175
Richard's RBBT 169.5, 175, 180, 200

Also does anyone have the BC's for Richard's bullets? Thanks!

I am getting 2940 with the MK and Cauterucio's 176 in a 24" barrel 7 WSM using 4831SC.

i Have had 4 7wsms. I will give the average of the rifles for velcioty. The 140,s with a velcioty of 3250 to 3400 FPS. 160 gr shoot around 3200. And 180 bergers at 3000 fps with 70 gr of retumbo. The wsm is a very effcient case I haven't noticed much gain with the 28 in barrels over the 24 and 25 inch barrels. Also with bullets weight 160 and under IMR 7828 is the fastest powder to use it gives the best velcioty.

Chris,
What kind of accuracy are you seeing with the MK and Cautericio?

LOAD PLEASE?

My 160 Accubonds shoot 3030 fps from my 23" Browning and RL 25. Accuracy is .45" at 100 yds.

I cant rember the load it was RL 25 and 162 A amx. I stopped using the rl 25 because I got a lot that was way to fast like Rl22, and got a bad taste for it. I would try Imr 7828 and 160 grain. Its been a while since I shoot the 162 a-max.

The Cauterucios are shooting 0.187"- 0.500" at 200 yards and the MK are doing 0.250" to just under 0.750" at 200 also.
