[QUOTE="The Oregonian, post: 1080893, member: 51405"] I recently (2 weeks ago) got my first custom and had a load work up done at the same time. That was with his lot of powder and I need to move to my lot. I have done 1.5 load developments so far...it seemed to take a lot of work, meaning shooting time. I checked in .5 gr increments with 5 shot groups, then went to .2 gr for fine tuning. I would like to avoid that long process. For this. Should I look for same muzzle velocity as previous lot and then confirm that powder charge with group size? Seems like the same brand of powder with similar muzzle velocity would have the same chamber pressure and barrel harmonics and this method would seem logical to me. It is a 30-06 with 24" barrel and 2790 velocity with 180gr Nosler BT using 57 gr of H4350 if that helps. Thx Tom [/QUOTE]
