Does anyone shoot this boomer? Recently aquired a pre-accubrake Mk V, and just wondering if someone has experience with it and maybe load recommendations?
.378 Wby

If I get beaten up to the point I can no longer shoot, I might have to make you a deal 
Always wanted one ever since I seen that big ###y cartridge.

Now that's the kind of terminal damage I wanna hear
444shooter,
I haven't shoot a .378, but did shoot a wildcat with about the same ballistics. A buddy had a custom Sako cranking 2900 fps with 300 grain bullets over my chronograph. The recoil of that thing makes my .375 H&H seem like a joke, and is similar to my Rigby. The recoil is jarring, and very fast.

I used to own a Brno 602 that originally started life as a .300 Win, and I had rebored and rechambered to .416 Rigby. Recoil was pretty stout, with 400gr Hornady @ 2500fps. But the weight of the gun was too light and the factory recoil pad wasn't much help.
Still not the worst recoil I have endured. That honor goes to a Ruger #3 in .45/70. Man, it was brutal!

444Shooter,
I may have said that wrong, I meant the .375 wildcat was very fast in the recoil department. My 416s recoil is considerable but doesn't seem to come back as fast as that .375. If you can handle one you should be able to handle the other without issue.
CZ/ Brno factory pads are a joke. A brick would work about as well. Cresent steel butt-plates were designed by Satan, I get scared just looking at those #3s.

Did you buy it from a fella on Vancouver Island with a 3-9 Zeiss on it?

When I started to build my .375 Ultra, I considered the .378 as an option. I rejected it because I was still smarting from the cost of my .416 Rigby brass - about $180 for 50 at that time. I chose the .375 Ultra, and have no regrets. I can purchase 100 pieces of brass without getting a bank loan, although the Ultra burns powder at a similar if slightly lower rate. I loaded 150 practice rounds yesterday, and it used up more than 2 pounds of H-4831.
If I was to consider a .378 I would not consider the MK-V action, as I do not favour multiple locking lugs, and I believe that the Weatherby stock design handles recoil poorly. Having said that, the Weatherby rifles are the smoothest feeding of any dangerous game rifle I have encountered, and that is a huge advantage. The best thing to happen for Canadian Weatherby owners in recent years is that Dave Jennings is now their warranty guy.

How do you figure the Mark V stock design handles recoil poorly? The cheek piece backs away from your face, get rid of the comb and you'd have about the same thing as a BDL... when shooting my .300WBY PRONE, I didn't even notice the recoil...just the muzzle jump.

When shooting a cartridge as mild as a .300 I doubt if you would notice the difference between a Weatherby style stock and a straighter stock which tended to recoil straight back. In these rifles, the Weatherby stock feels very natural, and in most cases the cheek weld allows the eye to immediately align with the scope.
A .378 on the other hand kicks, and rifles with the Weatherby style stock, to me at least, seem to exhibit greater muzzle rise. The higher the muzzle rises, the longer it takes to get back on target. When choosing a dangerous game rifle, I prefer to choose a straighter stock which recoils straight back. When a rifle recoils straight back it is faster to reacquire the target for a follow up shot, easier to work the bolt while the piece is in recoil, and your hand is less likely to be thrown clear of the rifle. I also want to be able to fire my heavy rifles from field positions including prone. The thought of shooting a .378 MK-V prone makes my head hurt and may teeth ache. When I fire a powerful rifle, I do not want the cheek piece to fall away from my cheek in recoil. I want to maintain my cheek weld throughout the firing cycle. Naturally this is a personal observation, and not everyone will agree.
I like straight stocks and not shiny, fancy looking ones. However I've got one WBY now and have had a couple lately. I realy like the design for handeling recoil on the big ones. I quess 9 1/2 LBS helps too. I'd consider them general hunting guns and not D/G rifles. You have to top them up from the bottom. They do feed very slick though.

What other loads did you use? I hear the 260gr Accubond is good.

Flippin' 378 Weatherby is what it takes to get detached retinas I find the recoil on the pre-brake Mk5's to be very stout and very fast, so it's not a maiden's caress by any stretch of the imagination. A good friend of mine fired his 460 Weatherby with the brake off and the next day he was at the physiotherapist, who observed. "Your shoulder seems to have suffered some sort of trauma"....right! 
Those rifle don't intrigue me a lot, but if that much power is what floats your boat, have at it. Regards, Eagleye.
