Just shot my new 6x45 today. It is also a 1 in 8 twist but 24 inches. Only tried one load just to see how it ran. I loaded 87 grain v-maxes with h4895 and shot two groups at around 3/4 inch at 100 yards. One was 5 shots and the second was 4 shots as that was all the rounds I had left. This was shot prone over my buddies tool bag in his field. Very happy with it. I am sure off of a bench with a real rest I could have shrunk the groups in half. As far as the previous poster goes I had no problems stabilizing the 87 grain bullets.
