So I am finally getting ready to send a rifle off to Jess and have it turned into a 35 whelen. My question is what twist would you recommend? I was planning on the 3 grove 1-14. Then I was looking at hammers and some of them needed a 1/13 or faster. Seems like everything is going to a faster twist these days for better bc. Problem is I plan on running cast and pistol bullets also. Anybody have experience with the 1/12 twist with cast loads? Thanks
