The 378 Wby is a cannon! Trajectory is like a 22-250 varmint rifle, but with 270gr bullets! Handloads can best Weatherby factory ammunition, especially with the new slower powders.

Yes, 300gr Hornady FMJ's and Partitions at 3000 fps with IMR-7828, i was young and slap full of piss and vinegar, bought the MK-V Weatherby at Carter Country Sports in Houston Tx 1986, the rifle came magnaported, after a few ears it developed a barrel bulge at the ports, 'Smth buddy took pics for Weatherby, cut the barrel and crowned it at 24 inches, with that he dropped it into a fully bedded and pillared Pacific Research stock.

I can say to this day nothing has slapped the piss out of me like a 24 inch barreled 378 WBY in a syn stock, ho lee damn, a real eye opener! ; ]

BTW, the little 2-7x33 Leupold in Leupold dual dovetail rings and bases never missed a lick, that rifle was a shoulder fired cannon, BTW, at 'Smiths request, the action was drilled and tapped to 8-40 threads and ring halves were cemented. LOL

Mine's necked down to .30 caliber, and it seriously reaches out and touches things. So far just moose, caribou, and elk.

No thanks.😊 The old H&H version is good enough for me. I can see the recoil as not just heavy, but fast too…bad combination.

Yes, both recoil force and recoil energy are very high.

LOL, maybe the chicks would have dug a brand new Capitol C betwixt the eyes ; ] never got kissed by that 378 WBY, was sitting on a low rock, back against tree, rattled up a nice buck, shooting off knees Knight MK-85 54 cal with 150gr Pyrodex P under sabot 325gr Barnes gaping HP, i felt it, but didnt break skin, the buck fared much worse.

The old British cartridge designers and the mid American cartridge designers got most things right as to bullet weight and velocity.

The Kynoch double rifle cartridges, 375 H&H, 416 Rigby, 404 Jeffery etc produced the necessary bullet weights with velocities that produced reasonable recoil that allowed average men with reasonable practice to learn to use them properly. More velocity allowed for flatter trajectories that made cartridges more versatile, but at the expense recoil that many could not properly handle. Ditto the mid American magnums like 264WM, 7mmRM, 300WM, 338WM, 458WM.

I, myself prefer a slower push than the faster cartridges produced. Sharp recoil is not for me. For that reason, I would not use the 378 Weatherby. By reputation, it is more recoil than I want to learn to handle. Therefore I have a 375 H&H and it's slow recoil push instead.

Through the course of shooting at a lot of ranges and having friends that are rifle loonies like myself, I have had the opportunity of shooting damn near most calibers.

I don't seek out recoil, but I am not particularly recoil sensitive.

Biggest I have shot is a .500 NE double rifle.

The only one I shot where I wanted no part of a 2nd shot was a .378

I originally started this thread, because a family friend left me some 378 ammo. If any of you can use new Weatherby brass and bullets, let me know and I’ll explain the details.

If your going to Africa use Barnes bullets nothing better, l use 7828 because l have many pounds of it but l hear from some that the African heat really makes them hotter. Try powders that are temp tolerant.

Just don't shoot a buffalo with a 270gr LRX.....while it might be great at 375HH velocities.....it's just not up to 378 speeds...

How do you see it failing?

I think "African heat" raising pressures too high is a myth.

In normal hunting seasons (I've been there from May to September) it is no hotter than the Midwest USA in the Summer time.

Cordite was more temperature sensitive than modern powders but so what?


Don't blame me. I voted for Trump.

leave some on your dash heat in the sun and try them against some that are cool. Use a chronograph like l do then see the diff, spreads of +100 ft/sec will be seen. If you are using compression loads and over + 110 grains. Let me know your results.

Why would anyone in their right mind leave cartridges on their dashboard in warm weather?..
