Not shure if I am asking this wright, my TC Hawken in 54 with a 1/48 will shoot one ragged hole with 85 gr by volume of FFF Goex and a PRB at 50 yds not shure if this load is max as far as stripping the patch or groups getting bigger because of to much pressure because I stoped when I got to this point. Now lets say the group went to hell in a hand basket at 90 gr. what advantage would I get with a 1/66 barrel more range, more velocity what? what is your favorite hunting load with a 1/66 barrel for this prb. I guess I am looking for a excuse to get a 1/66 barrel for my Hawkens
TIA A Nimrod
