Does anyone here have one of these? I have been offered a Weatherby Accumark rifle in this caliber in a trade. I have read the reviews and the ballistics seem pretty damn impressive. I am just trying to find some real feedback on it from somebody who actually hunts with one. I do hunt whitetail in a few places where a 400+ yard shot could be pretty common.
The ammo is expensive and I have heard the recoil is brutal, but is it worth it?

I shoot the .300WBY and its too much for Whitetail and most Muleys. The 30-348 is a step up, and the 30-378 is another step up from that and way too much for deer. They really ruin alot of meat.

If you go Weatherby reload or its going to break you. The thing people think alot about the .300.30-348, 30-378WBY is "Hey I reload I can make it perform like a 30-06" ...WRONG. The Weatherbys have too much case capacity to load safely with light loads. You can load down a 300WBY by using low end 300WINMAG loads but be careful. The 348/378 IDK about lighter loads.

I personally wouldnt trust any .30 bullet made to expand at 2500-3500FPS to perform well at 30-378 speeds under 300yds.

As far as the rifle goes though they are sweet rifles.

Thanks for the info, that's what I was afraid of. The trade is still a pretty good deal though so I may go through with it anyway. Even if I don't use it for hunting, I can turn around and sell it. Would it be okay for elk? I have always wanted to go on an elk hunt.:laughing:

I think it would be great in 180gr-200gr bonded bullets for Elk. If you buy the $65 a box Weatherby ammo the rounds are already top of the line.

The biggest drawback to it is throat erosion. Expect to see erosion start at less than 200 rounds. Ask how many rounds have been down the tube. If the guy doesn't have a log book or can't give you an accurate number, PASS. If it's a great deal, consider rebarreling if you're not seeing acceptable accuracy.

At over 100 grains of powder per cartridge loading isn't cheap, but definitely cheaper than buying factory. I can give you some recipes if you are going to roll your own. There's also no sense in using anything but VLD's, so don't expect to stuff a core-lokt in the case and call it good for long range work. There's no sense in half-assing anything with this cartridge.

For 400+ yard whitetails it's overkill. For 800+ yard whitetails and 500+ yard elk it's in its prime.

hmm, 800+ huh? That would be easy to do where I hunt, I have just never considered it with my .308 carbine. If I go through with the trade, it looks like I am going to have to save up for some top of the line optics:grinpimp:

Im not too familiar with weatherby cartridges, but the cursory wikipedia glance tells me that for white tails, this is overkill. I can personally attest to the damage a 7.62x54R Barnaul 203gr. will do on a deer from maybe half of your desireable distance. Its brutal...Simply put, iv switched my deer rifle from my nagant to a 6.5mm carcano. Its quite rare to get a shot over 200 yards here in my area...and most guys get away with the good old 30-30.

Sounds like you need the range and power, though. What about a '06? Would probably be cheaper! Weatherby was always a pretty "high end" rifle from what i remember...but or the kid that already has all the nice rifles, a fancy high power lead thrower is always nice!

There is no such thing as overkill:D

Like Brain said the throat erosion is a real problem with these. Most will have a barrel life of 500 rounds and probably quite a bit less with hot handloads.

It does kick like a mule:laughing:

All in all it is a very sweet gun other than the barrel life issue.
