hey guys im seriously thinking about buying an accumark in either 340 or 338-378, it will serve as my bigger hunting rifle and range gun/starter long range setup. either way ill likely have it accubraked and depending on how much it bucks with the brake i may put a mercury reducer in the stock. ill be planning on shooting 185-200 grain bullets, likely barnes. given that what would you choose and why?

340 or 338-378

.340 hands down, I've used one for years and with top end loads it will do everything a 338-378 or 338 Lapua will do and you have the luxury of making your brass from 375 H+H which I have always done. I love the 340 Wby and have found it to be the killingest cartridge I've ever used
i also have 340, 30-378, 338-378 and i you are wanting to use 180-200 grains i'd go with 30-378 depending on twist.
340 will do anything 338LM guys will use since there are very simailar with ballistics. I use Barnes 225g TTSX BT and they shoot 1/2 moa @ 100 yards and it is a stock accumark with accubrake.
338-378 is also fun shooter but you will need to consider the ballistic point of view with 340. compairing how much power i use out of 338-378. it is not worth buying over 340. Also you might want to consider going heavier bullet with 340
If you need more info about why 338-378 will suck up 10-20 grains more powder to achive about the sane energy, FPS PM me and will build a quick chart and send it to ya.

The .340 has a fine reputation as a game killer, and so it should. Any cartridges built from .378 Weatherby cases will be expensive, so unless you have deep pockets, it might be better to avoid that one. Another option you might consider is the .338 Edge, Dogleg has quite a bit of experience with that one, so if he doesn't chime in, send him a PM. Based on the Ultra case, Edge brass is more reasonable than the big Weatherby cases.

What is the point in buying a large .338 rifle and shooting only the litgher bullets?? If you are looking for a .338 cal rifle start with the 225's and go up from there!!! I have loaded for and shot alot of large guns .338 WM, .340 Bee, .338 RUM., .375 H&H, .378 Bee, .416 Bee and Rigby. And to buy and use a .340 or .338-378 with light bullets would be like buying a jacked up 4x4 diesel truck and putting racer track tires under it...........sure it would work but you could do alot better!!!!!
You will find that the .340 weatherby will do very well with the 225-250 Gr Barnes TSX, Also the swift A-frames in 250-275 gr will delvier the goods when needed. And you also mentioned that this rifle may be used in long range applications.........................light bullets are not what you want to use!!!!
If you are planning to use say a 210 gr bullets for deer etc. youy can`t go wrong with the 210 swift Scirrocco II or the 210 Barnes. Some may recommend the Accubonds in this caliber but I have had 3 fail this year only giving me an avg. of 8" of penetration in 3 different animals from 3 different guns and 3 different calibers. I would not recommend the Accubond at this time for the large animals.......!!!!!!
The lighter 210 gr bullets make for a wonderful bullet in the smaller .338 like the .338 Win Mag. or the .338 Federal...etc.
As some of the guys mentioned before if you only want to shoot the 200 gr bullets or smaller then you would be better served with a .300 weatherby, or the .30-378 weatherby which i have loaded and shot both. You can get 200 gr Barnes TSX bullets out of that large 30-378 somewhere around 3100 fps mark with no serious pressure. makes for a great elk rifle!!!
Hope this helps!!!

In a 26 inch barrel the .340 Weatherby is superb. A better hunting cartridge than the Lapua... and a bonus - it is easily built on any standard magnum 700 action.
A 338-378 needs a 30 inch barrel and a lot of powder ... it's a big pig.

the reason i dont want to go with a 300 is because i already have a 270ai and a 7mm rem, after more research i plan on shooting a 210-225 tsx for general hunting of deer and maybe moose/elk and will still be able to shoot up to 250tsx or other 300grn bullets, so i think that shooting a little lighter bullets for everyday stuff and being able to move up to bigger bullets if i want and when i go to africa in 2014 will be a better choice than going with a 300 bee, also i know that light bullets are no good for long range thus keeping the option for larger bullets, if im going to set up to shoot 800-1000 im most likely not gonna shoot a hunting bullet like the tax
I don't mean to be negative but a rifle set up for 800m is hardly the right tool for a running pig @ 30 m.
If you take a braked Weatherby to africa I predict you will not be popular.
And PH's don't like long shots anyways.
That said I kind of regret not buying a .340 it's a hellava cartrige.

Here 7 REM MAG;
Thought I'd throw some teasers up for you to peruse.
This is my 340 Wby, I bought a brand new supergrade in 338 WM and when it came I immediately yanked the barrel off and ran a reamer in for the 340, never even fired it as a 338. I had to move the bolt stop back and grind the ejector bar, no big deal. Now I have to open up the magazine opening in the action and build a new box for it and it will be done.

The .340 is expensive to feed. Brass is pricey for the quality (unless you like to fireform). The .338 Ultra will get you into better ballistics, without a belt and much cheaper to shoot. I love the Mark V action, but really overkill and hard to find upgrades for. I sold my .340 to get my RUM and am very happy with it. I still like the .340, just not worth the cost when the RUM does it better for cheaper.
If you want to shoot real long range (beyond 400 yards) you will want 225 grain bullets and up. I would start by looking at the 225 TTSX or Accubond. The 250 and 300 grian Bergers are impressive in the wind.

the nice thing with a belted case is , you can headspace off the belt when fire forming new brass for the first time .
Actually loaded warm you can get 3100 out of 250s in a 26" barrel and over 3200 with 225s, and still get 5-7 loads from a Rem .375 case.
