I posted this ? over on the trad forum,and was told that I might have a better chance here.I have a T/C Treehawk with a 1-20 twist barrell, I need info on some bullets for this rifle, My other rifles are 1-66 and 1-48 twist in which I shoot PRB. I would like to try some conicals out of this one,I will be using it for deer hunting with shots about max at 75 yds. Thanks in advance for any info. :?
