I just started shooting at 14" TC in 6.8, loaded with 115g Sierra MK's. The first 4 rams toppled slowly, and I rang the next 6. The last 3 were hit pretty high too - didn't quite have the momentum. One of the setters said the targets were set solid.
I'm now looking for 130g and 135g load data, if anyone can recommend some.
Otherwise, really like the cartridge.
