I have playing around with some 208 amax's in 30-06 24" barrel. I work on using a ladder test then followed up with a OCW test. I found a good node between 57.5 -58.5gr Ramshot hunter.

Load:
208 amax
Lapua Brass
Hunter powder
Wolf Primer LR
COL @ 2.636 at ogive / .022" off the lands

Target is at 320 yards. Wind was pretty bad, decide to shoot anyways. Winds at 5-7mph.

top left 57.6 grs.
top right 57.9 grs

Bottom 58.5 grs. Flat primers



Update on 208 amax load. Retested again using 58.0grs as ocw, and tried different col. Shot again at 320 yards. The S marks are sighters.
