Home Forums Hunting & Shooting Express Rifles and Big Bores Only 338 Lapua or 340 Weatherby?

As a side note on the ease of building and owning a 340 Tyrannosaur. The late Dick Nickel did my barrel and chamber and after boring what had been a 300 WBY to .338, he merely ran a 7STW reamer into the back end of the barrel and it worked wonderfully - still does. NO extra cost for special remamers, and no need for special dies, either. I just use 340 WBY dies and don't run them in all the way to the shell holder. Re Size just enough to get good neck tension and easy re chambering and there we have it.

I agree. (Consider the big .338's from Lazzeroni and A-Square too.)

I think the more pressing question is - Why are we talking about .338's (of any case size) in the "Big Bore" forum?

Check out the price of loaded ammo for the 338 lapua and compare it to 50 bmg. In midway catalog the average price of loaded 338 lapua ammo is $6.03 a round, the average of 50 BMG ammo is $5.88.

now check the price for brass. Average cost of 338 lapua brass is $2.66 a round, and 50 BMG is $1.97 each.



now pull your head out of your own backside.

338RUM! Mainly for the cheaper brass. I have a friend with one in a sporter profile (ie light) but has one of those evil muzzle brakes on it - makes it shootable.

It is a sub-MOA performer (not as accurate as a tactical 338Lapua though) but he still shoots Fallow deer at 700m with it.

Hey Jack Azz, if you dont spin-doctor things it is not too hard to figure out, if you are trying to make accurate ammo for each (apples to apples) a quality accurate bullet like the Hornady A-Max is $2.35 a bullet for the 50BMG.
Just as accurate if not moreso for the 338 Lapua is the Sierra 300gr SMK it costs about 57cents a bullet.
It takes about 2 1/2 times the powder (2 1/2 times the cost)for the BMG to fire the slug.....just admit you are wrong and it's all good.

You wont touch 3300 with a RUM and a 300gr,even with a 40" bbl.

If you can keep your head from exploding long enough to reply, what are the makers saying regarding a match VLD bullet at 3000+ fps in a 3 groove?

Oh, I forgot "3 groove nitrided barrel"..my mistake1

interthem, The ONLY thing that makes any sense of your post is your signature line dissing "nsaqam" for being a dipp schitt.
Betting on 3300 w/Berger 300s from a 34" 3 groove is the Spit Take line of the year so far


Do yourself a favor if it is not too late and order anything but a 3groove for this project (worst possible choice) and buy a good chronograph to realize the disappointment of not getting close to 3300fps with this project.

oh, yes, the mythical curse of three grooves.

I think its pretty clear that loaded ammo was actually cheaper for 50 bmg vs 338 lapua. Apples to apples on a large national retailer. I wasn't even factoring in the dirt cheap milsurp machine gun ammo available here locally ridiculously cheap.

Obviously the bullets and power costs will be greater with 50 vs 338. but I spoke specifically to brass in my original post as well.

So I was clearly right about ammo prices and partly right with components, i.e. brass. Any way you shake it I would say its more than "not even close" as you stated.

while we are in an admitting mood I didn't see you admitting to being wrong about ammo?

Also you have been very disrespectfully from your original post. I won't repond as juvenilely as you did but if you would care to take this to a more private mode of conversation I would gladly continue this conversation.

Instead of hiding behind a fake alias why don't you come clean who you are? It might make you less likely to make such rude statements.

.............If you want that sniping reputation prestige go with the 338 Lapua. If you don`t desire that kind of reputation in a cartridge, then the 340 Bee will do anything you want it to do.

I myself went with a new 338-378 Bee Accumark last year. Partial to the Wby round despite its appetite for powder and cost of brass. Very small percentage of overall hunting costs.

Here is another option. A square 338 Excalibur. This chart has ballistics for there factory loads. http://a-squareco.com/Ballistics_Chart.html Here is the 300gr bullet

Gunner, you mean, steel!......grin! The small pocks are from a .260, the clean through holes are the work of 300 grain Bergers at 2850fps.

How thick is the metal? What distance and what weight/fps of 260 bullet. I believe that the 264wm with 73gr h4831 pushing 85gr hp 3800 to 4000fps would go through as I came close to pushing one through 1" thick boiler plate on a chain at 100yrds. (speed Kills)

Of the 2 asked about, the 338 Lapua hands down. More factory choices availible, more factory rifles, more brass options, lots of once fired brass at discounted prices, very accurate, lots of load data. The 338 Lapua can be run on a Remington 700 action, as Remington themselves do.

1/2" mild steel at 500 meters. 130gr VLD's at 3000fps.

It would be interesting to see what 67grs of H4831 behind the 130gr VLD at 3500 fps would do.

Looking at the numbers on the 338 Excalibur starting at 3250fps with the 300gr vld it would still be moving 2660fps at 1000yrds with 4714 ft lbs energy. Now thats smoking. Zero at 900yrds mid range is +38.9 inches and -21 inches at 1000yrds.

Ok then, I would pick the Weatherby because it is not a Lapua.

nice shootin' Pat.

Gunner

I have a lot better reason's but along this line of thinking I would pick the Lapua because it is not a Weatherby.
