As I promised, I finally chrono'd my 338RUM 200ET load. Here's the specifics:
Fed Brass @ 2.74
GM215M
93gn of IMR 7828SSC
COL: 3.62
AVG 5 shot velocity: 3149fps
Also, I re-chrono'd my 30-06 180AB load. The first attempt was suspect as my 5 shot avg was 2922FPS. I attribute this to the ammo sitting out on a sunny day while I was chrono'ing another rifle/load. Well today I got more realistic results today, an avg 5 shot velocity of 2823 fps. The load is:
Nosler brass @ 2.48"
GM210M
55.5gn of H414
COL: 3.39"
