Most h4350 data is very conservative. Between a ruger murican predator ,tikka ctr & savage axis2 we've been loading h4350 41-43g with 123scenar,129interlock & 130 gc. The tikka takes more pressure evertime. They all group moa easily. I've worked up win 6.5 staball loads for the ruger that I've tested in field with great results also. No chrono yet but these rounds are all 27-2800 according to data.
