Norma Oryx 300gr or Barnes 350

Backyardsniper, H 4350 is the powder I want to use in my 375 H&H(s) as well. please let us / me know how it works out for you. I'd like to see as much data as possible on the loads you work up.

Will do. I have a limited supply of A Frames so I'm going to do the initial work up with 300gr Sierra and then move to some 300gr Accubonds and once I get some basic idea of how things are behaving I will load the A frames and hopefully it will not take many of them to get the groups/velocity I want. I will start a thread on it when I start the work up. I also am going to try some reloader 16 too. It fills the case a little too quick, but it also generates a bit more velocity. For instance 110gr of H4350 gives me +/- 2410fps with a 500gr in my 460, but I get the same velocity with a better ES/SD with 106gr of RL16. With 77gr of H4350 being the starting load for H4350 I'm going to try that with the RL 16 and see what velocity it generates. 77gr of of RL 16 pretty much fills the case to the base of the neck/shoulder junction. I'm going to run them over the chrono and see what we get. I will keep y'all posted.
