Re: 14 twist wont stabilize 55 gr bullets
we have shot 50 , 55 , 60 and 63 grain bullet out of several remingtons no problem. the flat base you are taliking about is a shorter bullet than the BT so it would/should require a SLOWER twist. 35.5 of benchmark and a 50 balistic tip- .5" in 5 different remington 22-250s. average velocity was 3907. the 50s and the 63s were better than the others but our testing was not extensive. if the 14 twist was too slow the 63s would not group into .5". trying a 52 or 53 grain match bullet ( hornady, sierra, speer , berger) with the accuracy load from sierra manual would be good.
