Re: Sierra 6mm 85 gr HPBT
Go with the 85g Barnes Triple Shock X. At 3345 fps out of my 243 Win, it is nasty on coyotes and deer. At whatever velocity out of your WSSM, it will only get better. Forget about the horror stories of the past on load development for Barnes Bullets. The Triple Shock changed all that and is easy to work up. As for terminal performance, it just don't get no better than a X Bullet. My two cents.
