tejano.thanks.so if shooting 100 to 115 barnes or 110 to 120 noslers and other hornady weights in this class and requiring best accuracy then maybe shooting some hammers of different weights you would do what twist as there has to be trade offs.your or any others opinion.ps i spoke with the hammer people and they like a 7 twist from there i believe 103 grain and up to around 120 grainers.blackjack also likes 8 and faster..thanks again as i have the info but believe i have been overthinking this way to much.anyway i think 8 might be the right compromise..sorry for nitpicking and bothering others.
