I am a big fan of the .300 H&H myself, but no, you can't load it up to beat the .300 WSM at the same pressures.
In fact case capacity is just about identical. About three years ago I talked my gunsmith friend Charlie Sisk into doing an experiment. He first chambered a HEAVY premium barrel to .300 H&H and ran some loads through it, using various bullet weights and powders, while recording the pressures on a Pressure Trace strain-gauge system.
Then he rechambered the same barrel to .300 WSM, so that the new chamber used the same throat as the .300 H&H chamber. Charlie ran the same bullets and powders through the .300 WSM, and found that the exact same powder charges produced almost exactly the same velocities and pressures. Sometimes they would be slightly higher in the WSM chamber and sometimes slightly higher in the .300 H&H chamber, but for all practical purposes the cartridges are identical except for case shape and length.
In fact with both chambers the same powder (Ramshot Hunter) turned out to be most accurate. The groups were shot on and indoor range with a high-powered scope. I can't remember it exactly but knowing Charlie it was probably a Leupold. I do remember the entire rifle weighed over 30 pounds, so it held pretty steadily!

I used 69 grains of IMR 4350 with 165 Nosler Partitions in the .300 H&H. With the 26" barrel it yielded about 3000fps. That rifle/load worked on everything (mostly mule deer) that I shot with it up to 350 yards with a Zeiss 3-9x36 scope. Of course you know that the 1000 yard record that was set with the .300 H&H which stood for quite a few years.
My .30 WSM was also about the same velocity as the .300 H&H. I gave the .30 WSM A-Bolt Medallion to my middle son. He has moved to Laramie, WY and has an elk rifle in the .30 WSM. Now I am without a .30 mag. but who knows what the future holds.

Man I would love to see those recipes and groups!

If it is tourist season, why can't we shoot them?

For Wimbleton? The groups with the IMR 4350 in (3) different .300 H&H, Model 70's were consistantly MOA.

Actually from the test that John was referring to. As I currently load for .300 wsm.

The results of the tests were published in HANDLOADER magazine maybe 2-3 years ago, I can't remember the issue.
My own present .300 H&H is a Model 70 Classic rebarreled by Classic Barrel & Gun Works (www.cutrifle.com) in Prescott, Arizona. They make cut-rifled, hand-lapped barrels and very fine rifles. I have both a synthetic and fancy walnut stock for it, and as you might imagine it shoots very well.
But since I am a rifle loony I also have a .300 WSM (one of the new South-Carolina Model 70's, with fancy wood, that shoots very well itself), a Heym SR-21 .300 Winchester Magnum (also extremely accurate) and a Weatherby Vanguard Sub-MOA in .300 Wby. that also is right in there as far as accuracy.
What the heck I need four .300 magnums for I have no idea.
