[QUOTE="jsthntn247, post: 870613, member: 14894"] Here's how you do it in less than 30 rounds. 1. Find your max coal to the ogive of the bullet 2. Pick a powder that gives good case volume 95-100% (Retumbo is great for the 168 - 180) 3. Load powder from 2 grains under book max to 1 grain over max in .5 grain increments 3 shots each ( 7 - 3 shot groups for 21 total) 4. Seat bullets with .002 - .003 neck tension and a .010 jam 5. Shoot and OCW test with those rounds at 100 yards round robin 6. Pick your OCW group and load 3 shots at a .010 jam, just touching lands, and .o10 off lands. 9 Rounds total If your gun is worth a squat you will have at least a .5" grouping gun- capable of shoot stuff a long waays off.
