Would it be fair to compare the 375 H&H with a 300Win mag ?
Would it be fair to compare the 375 H&H with a 338 Lapua mag ?
I suppose those are really different purpose cartridges ?
Very different cartridges........ the .300 Win Mag and especially the .338 Lapua far more modern and designed for different purposes.
OK here we go.... lot of "IMHO" stuff to follow...
The .338 Lapua is probably more than 90% of hunters out here can REALLY manage. Unless you have weight and/or a muzzle brake to mitigate recoil....in a sporting weight rifle the .338 L is NO FUN at all. If you can handle the recoil, and take your larger game at longish ranges I can see a use for the Lapua round. Otherwise NOT for me.
Then again...If I was doing 400-500 yds on elk, moose etc, and wated to fling 250 or 275 gr slugs....the Lapua is THE tool for that job. A tremendous sniper round. Shot an Accuracy Intl with 275 gr slugs at 600 yds and my first 3 shot group went 5". I WAS impressed. Then again a very expensive and heavy rifle, with $2K worth of optics alone. Really unfair to compare such a modern ctg to the old .375 H&H.
The three seven five is a great "medium" rifle for Africa, or even Alaska. Pretty good all arounder for the world really. With 270-300 gr slugs the downrange drop figures are not all that different from a .30-06 and 180's. Not exactly .220 Swift FLAT...but certainly not .45-70 with a 500 grain "rainbow trajectory" either.
I've dialed 15" of UP clicks into my Winchester a time or three and rolled elk over at 325-350 yds. It works that far out there.
The .300 Win Mag one of my favorites and I have some time behind them on game and targets. Anything that flings 180 gr slugs at 3000 fps or a bit more is a GREAT N. American and African plains game round...with GOOD BULLETS. Velocity is nice for extending your point blank range but the slugs also have to put UP with all that velocity. Run into something at 50 yds and a std cup and core slug may fail at 2900 fps as it was designed for far less velocity. Nothing is free. Like Montgomery Scott used to say on Star Trek; "Ya can't change the Laws of Physics".
The .300 H&H doesn't compare all that poorly to the .300 Win Mag. In reality an extra 100 fps is probably indistinguishable by your quarry at all but the longest ranges. Could probably throw the new .300 Short Mags in the same basket as well. Most anything that can hit 3000 fps with the heavier slugs is an impressive killer at average ranges that average game is taken. Throw in the extra 300-400 fps of the really BIG RUM and WBY mags and you really have a heck of a LR big game rifle...IF You can handle it. Again...not many really CAN.
Velocity in a big game rifle is great internet bragging rights and fun to plot on drop tables....but here we go with some IMHO stuff again.... I have killed a lot of game with a .338-06 shooting a 250 gr NP at no more than 2450 fps at the muzzle. Everything from little 60 pound Impala, to mature bull elk and even a truly large Livingston Eland. NEVER once had to use more than ONE shot. One oof the elk was a lasered 340 yds too. Talking zero drama...they drop over, or do a short death run and they are down. Would a .338 Lapua shooting at an extra several hundred feet per second kill any better?? Maybe? But theres a stiff price to pay for all that velocity.
Killed a lot of game too with a lowly .257 Roberts and 100-115 gr NP's. Whats THAT statement prove? I have no idea. I'm simply sitting home...while my overpaid Plumber is installing a new water heater. This was a fun time waster.
