More important than pure accuracy for me would be its field accuracy and "carry-ability." The Echols Legend stock is a good start. But with that stock, don't even think about trying to use open sights. The comb is too high and straight. But it handles recoil really well.

I would also pay a lot of attention to the barrel profile and length. Most .375H&H barrels are too long and bulky. I sold my M70 Classic in 375 H&H after one Afric hunt for exactly that reason. The cartridge certainly does not need 26" barrels to achieve benchmark velocities. I would be thinking in the 22" range (maybe 23", which would look better with a Legend stock), and about .675" muzzle diameter.

Penrod does good work, but he is slower and more expensive than Redneck (Lee), whose work has never let me down.
