[QUOTE="nchunter182, post: 836775, member: 42015"] Highridge1 - I do have just under 1 lb of RL25 to try if all else fails. But I also have 16lbs of H1000 so I need to make it work! Jeff - Went out and shot today. Loaded one round each of H1000 90-92grs in 1/2gr increments. Seated the 300SMK .060" of the lands for a COAL of 3.865". Unfortunately today I guess my chrono decided to be finicky about the muzzle blast. Even though it was set up 20ft from the muzzle and my 280Ack and 300Ack didn't bother it a bit - my Edge velocities were all over the place. I've got to get this corrected so I can see what my velocities really are. Next time I'm going to repeat these loads and move the chrono out to 25ft. 90 - no reading 90.5 - 2873 what??? 91 - 2801 maybe? 91.5 - 2904 don't think so! 92 - 2783 uh - no Again today brass looked like it took a beating. Below is a picture of the 90gr load showing heavy ejector mark and shiny area were the bolt face wiped it. Wish I had a better camera so you could see what I'm seeing. You are spot on about needing to test accuracy at 200+ yards. The target below is typical of what I have been getting even when shooting different powder charges like I did today. This was shot at 108yds and target is oriented like I shot it. If it keeps shooting like this I'm just going live with it being a brass eater! Maybe I got a soft batch of Nosler brass? I see Bertram brass in the near future! Jay [/QUOTE]
