.300 Win Mag VS 375 H&H

Hello all,
My father and I have been arguing about what cartridge is superior. He just got a Blaser R8 in 375 H&H and I have a LR-1000 in .300 WM arriving next month. I'm really only interested in N. America for the time being. It seems to me that the .300 begins to outshine the 375 in ft/lbs of energy between 400 and 600 yards depending on the bullet grains and bc. If you all had to choose one cartridge for elk, deer, pig and maybe bear in N. America which one and why?

The 375 has an advantage only against brown bear. For everything else the 300 is the clear winner. 300 shoots flatter, has enough energy, and recoils less. For long range it isn't even close because of the superior 308 bullets.

The 375 is a DG cartridge that CAN BE used on all the species mentioned. Dang, I've even used my 404 Jeffrey, 416 Rigby, 458 Lott AND 505 Gibbs on pigs for practice.

Cheers.

I agree the 300 is superior on game for LR work in N.America.....excluding big bears at close range.
I used my Whitwoth 375 H&H Mauser on a few safaris about 30 years ago on everything from Impala to Cape buffalo. It is very reliable, superbly accurate, and has a trajectory comparable to a 30-06 using 180gr conventional bullets. Using 270gr Winchester Power Points, it performed well on all thin skinned game, my longest shot on a Kudu at 300 yards which was as long a shot one was likely to get in the area I was hunting. While I used the 375 with both solids and SP's on Cape Bullalo, it is a compromise caliber in my opinion. Overkill for thin skinned game, and too light for dangerous game. I very much preferred my H&H 450 Double for dangerous game in close quarters.

Not even close, this comparison is not on the level......other than the dangerous bears up to 75 yards the .300 will destroy that big ole' .375.... Much better ballistics, bullet selection isn't even close, cost to shoot me favors the .300wm by a lot. With a partition or triple shok over 200 grains I'd take on those big bears close also...

In this day and age of nearly instant access to information, it is not hard to figure out which cartridge has the edge in the external ballistics category.

Thanks???

My thing against the .375 H&H is...I've never seen it sold anywhere. Both factory and reloading components are easy to find anywhere I go. Plus the .300 gets the job done

I shouldn't pick here. I own both and both my 300win and 375h@h are very accurate... They really don't have the same intended use though (other than a blanket putting a hole in something) so I'll simply say I've seen my 375h@h put a hit on things that my 300rum couldn't even begin to match- I didn't even bother to use my 300win... I've used my 375 to split a frozen railroad tie in half with a few shots. I had put many rounds of 300rum into it and all I really got was a smoldering hole in the tie. I've done similar with rock busting too. The 30 cal. picks away... you unload on something with a 375 and it gets destroyed in a hurry. The lack of long range capability of the 375h@h can be ignored entirely if you look at the fact that a 375 is only really meant as a mid range cartridge. The 300win has a lot better bullet assortment in the long range realm, with better launch velocities too so that is where my 300win plays.

Just bring up the .300 Ackley and both of you are wrong about superiority...

And this is coming form a 7mm guy, who also happens to own a .300 BLK, .308 Win, .30-06 AI, .300WM, and .300 Ackley

Not a level playing field...two nearly totally different cartridges....out to 300 yards only your shoulder knows the difference, after that the 300wm blows it away, in the alders along an Alaskan stream chasing brown bears I'm grabbing the 375 H/H every time...not fair to compare!

The answer is why the big .338's are popular.
They are different animals, for different purposes, as this is LRH the .300 is clearly a better choice.
The .375 is probably my favorite rifle in the safe, a bunch of good memories with it. Prior to good range finders, 300 yards was about the limit for both, and for me the .375 clearly wins in terms of terminal performance.
Bullet technology has also improved a bunch, adding a little range to the .375, and making the .300's better in close.

Well.... If you have to pick one, and "it" will be your only cartridge, it will be the bigger bore! Big enough for most anything, adequately flat shooting to around 400 yrds., and.... can be loaded with cast for small game and/or small big game. I've got an excellent "trout load" with 285 grain cast!! memtb

There ya go. If I was allowed only one it would be the 375.

mountainman56, It good to see someone else saw it as a either/or question/poll!
