I have found the perfect load for my 6.5x47  . Lapua brass and 123 Scenars with 40.1 gr of IMR 4350 and PMC mag primers. I don't have a chrony, so I reverse engineered JBM with my zero settings @ 100yds and 600yds and came up with 2800 fps. I then used the click settings generated by JBM to shoot @ 200yds and 300 yds. They were right on. However, when I plug the cartridge, bullet and powder data into Quickload, and adjust the burn rate to get to either OBT node available for my 28"barrel, I come up with 2722 or 2969 fps!? Am I going about this wrong? |
