1st time doing this test. Interesting results. Primers were kinda flat, but no cratering. No heavy bolt lift. This rifle a damn dream in half to shoot. We gotta do something about that foam over the benchrest range though. **** is in every nook and cranny of my gear lol
All shots were done @55 degrees with about a minute between shots then a 20 minute rest between shots 5 and 6. Barrel just barely warm. Rounds single loaded and chamber was open between shots and rest. No loaded round spent more than 30 seconds or so in a closed chamber. Just long enough to chamber, bolt close and a few breaths to control my shot.
Ramshot LRT was all over the place. I guess if I had to say where a node was at would be between shots 8/9/10? However the SD for all 10 shots was only 16.3
VVN570 as a bit more stable on the graph. I see two nodes. Shots 3/4/5 and 6/7/8. Yuge jump between shots 1,2 up to 3 though. Almost 30 FPS.
I can see a direct correlation on the two nodes v's what printed on paper for N570. I really like that node for shots 6/7/8. Shots 6 and 7 were 1 hole with #8 probably still making it a sub MOA group. I think I'm going to load up 10 more at 78.9 grains of N570. Shoot them all over a chronograph, 5 at 100 yards and 5 at 200 yards.
I don't know what to think about the LTR. It's a ball powder, so took up less space. N570 was "sorta" compressed. Not enough to cause a mark from my seating stem, so I know there was less dead space in the case. Both loads were COAL of 3.700" or 2.817" off the O-Give. You see some really wild shots with LRT too. Looking at the entire 10 shot string of N570, you see more consistency.
I'd appreciate any feedback.
Thanks OSA
