Long target bullets can be "interesting" to find data for...

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.
