Re: 6-284 87gr vmax loads
I got this from the net and put them in my documents a few years ago. I recommend starting below any suggested loads and work up. These should give you some ideas.
53.2g of RL-22, CCI BR2 primer, Lapua brass, 87g VMAX seated 0.005 out of the lands. 3598 fps BC for 87 gr is .400 (have no idea as to barrel length)
Out of my 6x284 I'm getting 3,630 (Average of 7 shots) with a 87gr V-max. It needs 53.5grs of H4350 to do though.I've only shot coyotes with it and a few squirels ,which I might add turn into a "Red Mist"
88 gr bergers H-1000 is the most accurate all around High Vel load @ 3825fps
I began load development with RL-22 and was able to drive 87g VMAX's to about 3590 fps or so however I have since switched to RL-17.
I am currently using 49.3g of RL-17 and the 87g VMAX. I am getting 3697 fps +- 4 fps regularly. This powder got me an extra 100 fps (which is the whole point we are shooting this thing!) and the accuracy has been incredible! OF course I am shooting a 30" barrel.
