Is that the RPM or the 6.5x300. Reason I am asking is I recently purchased the Weatherby MeatEater Vanguard, but I am working in Michigan and haven't got to shoot it yet. The factory 127 LRX claim 3531 on the box. I have dies, IMR 869, and 150 of the 127 Barnes and was wondering if I might find a better than factory load than advertised. Either way, the Weatherby's are fast and expensive to load for, but I new that when I bought it. LOL. Taking it and a custom 300WM to Colorado for the fourth Elk season this year and I can't wait. I am assuming that it is the 6.5X300 judging from the powder capacity.3500 is what I get in my 6.5 Bee with the 127 LRX and 87 gr of RL33.
We should be able to best at least 3700 fps with the 123 AH
Look at the load data sheet posted on one of these last couple pages, that will tell youSo I haven't looked at all 55 pages. what is the real world speed increase with these? I saw where with the American ruger in 6.5 cm no real increase. Anyone have a before load weight and speed and new load speed for 6.5cm and 6mm? I dont see them listed on site?
