I wish I could get 3060 out of my 284, best I could do is 2900 with the Barnes xlc, the ttsx were slightly slower. The problem is that my gun has a long throat, don't know if it was like that in it's origional chambering or if the rechambering caused it. Most of the bullets I have tried touch the lands at 3.125, however I have to keep the oal at 3.000 or less due to the magazine length, I could seat the bullets out farther but then I would have a single shot rifle. It has a 22 inch barrel, I have reached 3030 fps with 58 gr IMR 4831 with the xlc but extraction was sticky. I have tried IMR 4350 and Rl 19 with the ttsx bullets but ran into high pressures even before I could get to 2850 fps. I did kill a wild hog last April with one shot using the 140 gr ttsx at about 2850, guess I should not complain to much.
