Throw them in a calculator, measure bullet length minus the poly tip length, if you're at 1.4 to 1.5 bet you're stable. I can send you 20 in the mail to shoot on paper at 100 then 400, look for keyholes. I will add, most my consistent/accurate shooting rifles rifles have a stabilization of 1.6-1.8 on sg scale.But I’m curious about the 8 twist 22br
