I think the .338-378 is the finest long range caliber you can buy. I have witnessed shots with a .338-378 Wby. that most would not believe. However, you won't even begin to notice a significant difference between them until you are shooting well beyond what most would consider "long range". Both are exceptional long range calibers, but the ability to shoot bigger, heavier projectiles gives the .338-378 the edge in the longer shots.We cannot improve our government by electing people that hate our government...

I had the same decision when I was getting my Accumark.  I looked at the ballistic tables and the .338-378 has heavier bullets and shoots flatter than the .30-378.  I like both the .30 and .338 calibers and can't say anything bad about either of them.  I am working up to longer ranges, beyond 450 yards, slowly because I want to master shooting at each step of the way.  I have used my Accumark to hunt white tailed deer and black bear and in the future it will be coming with me on a Moose, Elk, and Grizzly Bear hunts.Nothing is better than a Weatherby, big bore magnum, or a Colt.

Jerry I don't know of any where that youll be able to get a TRR in .338-378.  I know they make them but have no idea who would have them in stock.  You could try checking on gunbroker.com or gunsinternational.com.  I would suggest getting an Accumark, they are super accurate and probablly a good bit cheaper than the TRR without sacraficing any quality.Nothing is better than a Weatherby, big bore magnum, or a Colt.

bbrant720,

Is yours a Accumark? What is the OAL you are using for the 250gr Accubond? I just recently bought a .338-378 Accumark.

I purchased my Weatherby Accumark in .338-378 back in 1999 and never looked back. It is one of the most accurate rifles I own, and it's ballistics best the .338 Lapua by a couple of hundred feet per second with the 300 grain Sierra Matchkings. I think the .338-378 Weatherby Magnum is the finest .338 bore rifle you can buy.

30-378 Mark V is my favorite Rifle.
I do not own a 338-378 but I have a 338 Lapua Mark V and even with the brake it kicks hard.
Would expect that the 338-378 kicks even harder with it is larger/more powerful cartridge.
My 30-378 kicks like a 30-06 or 270. It is enjoyable to shoot at the range.
So if I was to pick one to shoot at a Range it would be the 30-378.
If your going to use it for hunting either Rifle size will destroy any animal in North America.

Weatherby compares the 338-378 to a 300 Win Mag but I say it is a little less as I have shot 40 at one range trip but had another guy taking some of the pain! Which is tolerable and the smile every time ya pull on that Timney is priceless 2.12 Oz  Smileyhttp://www.weatherby.com/support/faq/latest/items
