[QUOTE="coyotezapper, post: 1121755, member: 20438"] IMO your 1 grain increments are a little large. I would have used .5 grain increments. It looks like you have a nice flat spot in your velocity at 72 grains. I would load 6 each of 71.8, 71.9, 72, 72.1 and 72.2 and test again. The thing to look for here is vertical along with velocity. Find where your velocity is the same or close to it between each different load and this will be your powder node. Load to the middle of the node and fine tune with seating depth in .003" increments if needed. Barnes "X" usually need very little tuning once you find the powder node. If you have time load higher in .5 grain increments. At 2871 fps you are only around 54K PMAX, a long ways away from 64K. Your numbers are real close to QL numbers so you should be able to go to their max at 75.8 grains - 3006 fps. Remember [B]pressure = velocity[/B]. Once you get to 3000 fps you will be at max pressure even if you are below the 75.8 grains. Keep us informed of your progress and especially your hunt details. [/QUOTE]
