[QUOTE="BountyHunter, post: 22972, member: 12"] Shot the test at old Remington Range at Rob Ritchies house in the drizzle rain. Just as simple as I laid out. Nothing fancy. Thought about doing it at 100, but figured it was key to be able to plot each round on paper to see which one went where. Used pure white target with magic marker one inch dot at bottom. Easy to see bullet impacts. Figured distances up might be too close to clearly differentiate between shots at 100. That is why used 400 yds. Each round went up about 3/4-1 1/2 inches except when they started to cluster. You can look at shot string up, clusters and MV and sweet spots are easy to see. Then it just becomes matter of fine tuning. Figured you can do this with each powder and see what the gun likes. I know for me to find a range of 1.1 grains spread for a sweet spot, I will take that. Also ran out of up on target and loaded rounds. Next time I am going to go up a little more on powder, absolutely no signs of pressure and I think I can raise it up to 3000fps with the JLK 190. Got to do it before the Nationals Labor Day in NC. [/QUOTE]
