224 Valkyrie Update

Sierra recommends a 6.5” twist barrel for the #9290 22 cal 90 gr HPBT bullet however for cartridges like the Valkyrie, that can push them over 2650 fps muzzle velocity, a 7” twist barrel will stabilize the bullet correctly.

    Well I’m glad I ordered a 6.5 inch twist Bartlein barrel for my bolt gun to shoot 90gr at 2900fps. Now what do I do? Will I be shredding bullets?

    When will we see and be able to purchase heavier Varmint bullets 65 to 85 grain (explosive) in .224 caliber. I have the 224 Valkyrie 1 in 7″ twist barrel for Prairie Dogs. I shot over 400 rounds in June in SD, most of the heavier bullets were target HP’s (not much fun). Thanks for all the info.
