Hi MThunter,

Without doing a little research up front I' m not sure who might still be chambering for the .300 H&H straight from the factory. Hopefully someone on the board may know offhand. But as far as how it stacks up....

As loaded by the factories it operates at slightly lower pressures than either the .300 Winchester Magnum or the .300 Weatherby Magnum. It also has less muzzle velocity with all bullet weights. So it puts it smack dab in the middle between the .30-06 and the other two .300' s. Reloading can get a little more out of it...but it will not exceed the other two magnums.

It is a very good and useful cartridge, particularly for North American game. It is not nearly as common any more as the other two magnums so finding factory ammo is a little more difficult. If you reload that is of absolutely no consequence. If you are looking for something a little less common, and don' t mind the special considerations, it is a very wonderful cartridge. (As well as coming with a " storied" past.)

Good luck with your decision!
