Went out and tried to see how accurate the Rl 17 load that I worked up using the Barnes 168 gr xlc would shoot, brought along some rounds loaded with 70 gr IMR 4831 with the same bullet, that load averages 3115 fps. I used 68 gr of RL 17, five shot average was 3126 fps, extreme spread was 29 and Standard deviation was 13. My origional load was 68.5 gr but I backed it off a half a grain cause I kind of skeptical about what the pressures are, primers look ok, easy bolt lift but I would like to see some numbers as far as pressure goes with similiar loads.It was too windy to compare the two loads for accuracy, as far as velocity goes I am a little bit dissapointed. My 284 is another story, got a big increase in velocity but still have some work to do on those loads, I will share those results when i am finished.
