I always start with known data for a weight of bullet either identical or slightly higher then seat .010 off the lands with a minamum charge for that weight of bullet then work up in steps around .5gr
I worked up 190gr Nosler CC .308 bullets in my 300wm target rifle using 208gr Amax data and found it very simmilar.

The data I'm using calls for a OACL of 2.130. Using your suggestion I would go for 2.120, correct? For comparison I measured a 50 grain Federal that I had on the bench and it was 2.060. Why so short as compared to the data in the book? I haven't filled anything yet, just using unprimed cases to get it all in order. Now I need a bullet puller.....
