Re: 6.5 x .284 I need load info.
Mine is pushing 130 Bergers to 3195 fps without pressure but near max. RL17 gives better velocities by far. Start at 49.5 and work up. There isn't much data out there with the 130 but I posted mine on Reloaders nest in the load data section. I have it in .5 grain increments, it is at the bottom in unverified loads. My minimum was over 3000. Prior to that I had cases not fully expanded and carbon residue on the outside case walls. Max charge for my gun was 52.5 but it was a bad load, velocities suddenly became erratic and groups openned up a lot. I stopped at 52 you may have different results. My data was worked up using Fed 215 primers and it seems velocities are a little lower with other primers. But higher charges may be possible.
Looking at other's velocities and yours mule, I think I must somehow have an exceptionally fast barrel. I am not that up on what makes one faster than another, but I know I have run my velocities on two chronographs and they match closely. I am getting 2825 with 49.7 grains of H4831SC. But it is my most accurate load. RL17 I use 51.8 grains at 3195 and it gets .4 inch groups at 200. and 2 FPS ES. That 49.7 of 4831sc gets .3 or better at 200 but it is slower than I wanted to hunt with.
