Sorry not hands on but it was a favourite for 1000 yards shooting in the US for many years and it was designed for deer size game.

friend of a friend has one
seems to like it
sits somewhere between 30-06 and 300WM in terms of ballistics.
never understood questioning accuracy of a cartridge design though. pretty much all cartridge loaded appropriately in an accurate rifle will outshoot the shooter!
any H&H brass can be tricky and expensive to source though depending on your location
reloading belted cases can be a faff.
I am loading for a new belted cartridge myself so relatively new to belts
I think it is just easier to headspace off the shoulder but in the 300H&H that isnt as straightforward as it sounds due to the very sloping shoulders

Ahhh I believe you mean sloping shoulders. The H&H does not have sharp shoulders which is a feature of the AI and Improved type cartridges.
Whelen was a fan on the 300 H&H magnum for longer range heavier game. Ken Waters also was a big fan of the cartridge. A close friend of his had a rifle built by Holland & Holland for Waters and he chose the the 300 H&H cartridge for the chambering. His writings are still interesting and useful for older cartridges like this. Wolfe publishing does his articles in a book format.

yes, poor choice of words

I have also seen it described as "droopy shouldered" . When designed many cartridges had gently sloping shoulders and tapered bodies. With British ones the long cases were to accommodate the strands of Cordite. I think that the thinking behind them was also they fed into the chamber from the magazine better than a sharper shoulder.
Something we now know to be false if the magazine feed lips are correctly set up.

what are you shooting ? 6.5x55 is ok up to moose?

world of options before I would consider something which is relatively unique, very difficult to source and likely to limit your rifle choice by a factor of 10
25-06
270
30-06
308
7-08
6.5-284
284
7mm Mag
300WM
etc etc
.300 WinMag, will do what you're after without the 'hassle' associated with the 300 H&H - plenty of new and S/H rifles available.
Alternatively for a bit more punch with the heavier loads (at both ends...) the .300 RUM is worth a look - again a fair few factory rifles are chambered in it and brass from nosler is now available (Rem factory brass is not great..). Or if you want to go full pelt a 300 Lap Mag in a re-barrelled TRG-S (or custom action) is very hard to beat with the top 200+ grain loads.

very happy with my rum , 208amax at 3250fps
but I would agree that a 300winmag is fine for what the op is after

Unfortunately, I'd have to agree with the others. I've always wanted a 300 H & H. I was going to ream out a Ruger No 1 in 30-06, mainly because I couldn't easily find a bolt action long enough to feed that long case, it can be done with some factory actions, but does require a lot of metal removal.
Even over here, finding brass for a 300 H & H isn't easy , its availability is very hit and miss.
I'm not trying to rain on your parade, but a 300 WM or 300 WSM are excellent cartridges as are the other calibres mentioned above and are readily available.
That being said, if I came across British built sporter in 300 H & H I'd buy it in a heartbeat, they are very very cool. I'd worry about brass afterwards.
I guess it boils down to how bad do you want a 300 H & H

I wouldn't be looking further than .308 for the biggest of the reds we have to offer, I use 150grain and they all die, I've tried the .375h&h and to be honest it was a bit much for the size of animal and didn't perform/expand as well as the .308. I frequently find the .308 bullet lodged under the skin rather than exiting, which is good, it means all of that power has done its job inside the target and not wasted energy flying off into the wilderness. If you wanted to go heavier, factory up to 180 grains isn't hard to get, or you can reload up to 200 odd if I recall correctly.....

true, but......
Not only are the belt to head dimensions a variable lot to lot in same make brass the belts themselves have a wide variance in size between lots and more so between brass makes
if you look at the numerous forum entries of people using specifically 300wm in a competitive or long range environment, a huge proportion of them appear to be headspacing off the shoulder and ignoring the belt.
The belt stops much the forward motion under pin strike that a belt-less case has
combine that with well fired brass, warm loads and SAMMI spec full length sized brass in a slightly oversized chamber and you get this:

Excellent advise bewsher, I've reloaded for a number of belted cases over the years and have always adjusted my dies to headspace on the shoulder to avoid the situation you describe. The 7mm Rem Mag in particular had a bad reputation for oversized chambers. I haven't heard about to many lately, so hopefully the manufacturers have dealt with this problem
