[QUOTE="KDB, post: 375063, member: 18510"] I ran a ladder test a few weeks ago at 1K using Retumbo and 208 Amax's. My chronograph was reading unreliably so I don't know the velocities, but I started at 94g of Retumbo and ran it 96.5g in .5g increments. Bullet was lightly jammed in the lands. 95 grains was my best 5 shot group. Very little vertical spread and 4 of the 5 shots were inside 5 inches. Under corrected for the wind on one shot that blew my group to 10 inches. 95 grains was a little on the hot side with the 208's [/QUOTE]
