You are going to have to drop it into the 2650fps range to get good accuracy.
Have a hard look at RL-15...the powder of choice...just sayin'!
IIRC I was up around 2700fps with good accuracy with that powder.
Admittedly, it has been 10 years since I loaded for the H&H.
For the long bullets you want to use you should have a look at the 375Rum or even the 375 Wby. I prefer both to the H&H.
Good luck man!
The OCW workup will tell the tale where the best accuracy/velocity combination is concerned. The reason my first attempt failed was a combination of issues with my bench technique and my scope mounts working loose. Both of those issues prevented me from generating useful data. Believe me, BOTH of those issues WILL be resolved before I start slinging $2 bullets down range again.
At this point, I see no reason to change powders. H4350 has done what I am looking for so far. Pending data generation, who knows?
The same cannot be said of the nut behind the trigger, however. I'd change that out, but I don't have another one.
Where chambering is concerned, the whole point of the excercise is to determine the potential of the H&H when loaded to take full advantage of the high bc bullets that are now available. I am looking to explore the limits of what I already have, not justify yet another rifle (as much fun as that is).
