From what I've read from people like Ganyana, Kevin Thompson and other PH's whose names I tend to forget, is that dangerous game like buffalo and elephant - which are usually shot at ranges of 50 yards or so - are more affected by slowing down the velocity of the H&H round to approximately 2400 fps as to provide better stabilization/penetration. I would guess that the same would hold true of other .375 caliber cartridges, no matter what the name brand. Perhaps the situation changes with monometal projectiles. I think most dangerous game cartridges send their projectiles off at around 2100 - 2400 fps as to maintain projectile integrity/penetration. If you increase the velocity of a projectile for use on dangerous game at close range, I could understand how bullet failure could increase. I see the faster .375 caliber cartridges as more of a large plains game set-up whereas the H&H velocity is more an all-purpose (plains-game and dangerous game) set-up. Ganyana specifically states that any .375 caliber bullet travelling faster than traditional H&H velocity is no good for elephant. Once again, that may change with monometal projectiles. I believe he says it does not matter although I think Saeed would disagree with him. Any way, I don't understand why there is such a need for the extra velocity with the 300 grain or larger bullet out of a .375 caliber cartridge. The way I look at it is that the 300 - 350 grainers travelling 2300 - 2500 fps are for dangerous game at close range. The 270 grainers travelling 2600 - 2800 fps are for large plains game. These velocities work well for the game intended and always have. I also think most people are going to do better long range work on large plains game with a lighter projectile that recoils less, enhancing accuracy. I know I am better at long range with a 270 grain bullet at 2700 fps than a 300 grain bullet at 2800 fps or more. The faster 300 grainers just kick me too much to be accurate at 250 yards or beyond. I think the H&H round is the best of all .375 caliber cartridges for all around use but that is just me talking.

Thanks and take care,

After seeing a very large amount of game killed with a 375Wby and my buddy's 375 Ackley, I believe I have a slightly different view of what these cartridges can do, vs the H&H. I've hunted it several times too and have enough experience to know what it can do as well.
How much actual field experience on all sizes of game with the 375Wby or Ackley do you have to base your statements on? Your post is basically the same bit of copy that everyone uses to berate these cartridges.

I'm getting similar velocities with 300 gr Failsafe bullets and 89 grs of Normal 204. Not bad, but it kicks like a MULE!! All I can handle, and indeed, IMO at limit of what a human can be expected to handle with accuracy. It is is accurate as well. Hard to imagine you need more for anything on the Planet Earth.

OK, my actual chrono'd results before and after re-chambering are:
24" barrel.
H+H, 260gr Accubond, 2790fps, Wby 3000fps.
H+H, 270gr Woodleigh PP, 2710fps, Wby 2925fps.
H+H, 300gr Woodleigh PP, 2610fps, Wby 2830fps.

I re-chambered to get better case life and positive headspace so I could load to not worry about the belt, rarely have to trim the brass and accuracy is actually better.

Chuck,
I have a 505 Gibbs, the recoil is totally different to ANY cartridge I have used, sure, there are cartridges bigger, but I haven't used them. I get 2350fps with 600gr Woodleigh SP or Solids with modern brass and pressures. Never understood why the original bullet was 235gr, then went to 600gr at such a docile speed of 2000fps, doesn't make sense to me, but anyway.

Cheers.

If you really want to up the ante, get a 378 Wby. Most find it intolerable to shoot, but the ballistics are awe-inspiring. How about 3,180 fps with a 270gr bullet...can you say 400 yard Elk/Kudu/Eland rifle? It is also the perfect platform to use the 350gr 375 bullets, having the case capacity to really get them moving along. I'm not a proponent of long-range shooting...I think you miss most of the fun of hunting....but if you want range with a 260 to 350gr 375 bullet, that's the ticket.

My goal is to have a rifle light enough to carry all day, even when wearing snowshoes, or waiders when trudging thru knee deep water will moose hunting. I'm not to concerned with the recoil, I had a 7 lb 338 win mag that kicked pretty fearce. It was a joy to carry around while hunting, and I do most of my practice from feild positions anymore anyway. I only do initial sight in from the bench using my past recoil pad. If its too brutal I'll get a muzzle break put on it, I'd rather an easy to carry all day rifle than an easy to shoot all day rifle that was too heavy.

This statement may have been true 10 years ago, but, with the introduction of tough bullets like Woodleigh, Nosler Accubond, North Fork etc, it really is a non issue these days. Woodleigh are some of the toughest bullets out there.

A non scientific example of the 375 WBYs effectiveness. We hunted Zambia a few years ago and the PH although having many years experience had never seen a 375 WBY before. It was a full 21 day safari and we shot quite few animals. I had some good days and made some decent shots. The PH's comment was "what the Hell is that" after about the 3rd animal just piled up after the shot. I personally was most impressed with a big zebra stallion that just dropped in his tracks without hitting any significant bone. I've shot a number of zebra and never had one not run 50 to 200 yards. I don't know if it was me, the cartridge, the Northfork bullets or what but the 375 WBY sure worked wonderfully on that safari.
