240 vs 243

I have a Mark V ULW 240 Wby with a 24" barrel

85gr TSX adv vel 3500fps actual vel 3445fps
100gr NP adv vel 3406fps actual vel 3234fps

Wby Vanguard S2 243 20 inch barrel 80gr Federal Blue Box claimed 3330- got 3155/3160/3149

Hunters/shooters are missing out on all cartridges when utilizing short barrels. Personally, I would not waist my money on short barreled factory rifles, if I'm pursuing velocity and accuracy. Custom rifles accompanied with a 26" to 27" for standard cartridges will surpass accuracy and velocity than factory rifles. I've had many custom rifles built and they always championed factory rifles for velocity, accuracy and function. My custom 270 Win. is near completion, and yes, a 27.5" fluted barrel will accompany the Remington 700 action.

Again a INferior Bullet Put the SPBT Sierra in the 240 3200-300- and see the DIFFERENCE ! LOL RJ

Just comparing factory ammo options currently available at their claimed ballistics

Tikka T3 Action with a 26 " - 1-8 " twist JC Custom SS barrel is in the NEAR future Here ! Oh and the cartridge will be the Most Excellent 6 MM caliber going the 240 Weatherby Magnum ! Its the KOOLEST looking too ! :dancingbanana: RJ

It will be good with the 1:8, keep us updated
 
Some of the anti-Weatherby stuff gets pretty funny. The .240 Bee, 6mm-06, and the 6mm-284 are so close in performance, that there is probably a greater velocity difference from rifle to rifle than there is cartridge to cartridge. If I was interested in a rifle of this sort, I'd probably choose the .240 Weatherby since there is a plausible theory that the Weatherby shoulder produces longer lead life than the others. But, if barrel life rather than performance was the overwhelming criteria for a hunting rifle, I'd either load the .240 to standard cartridge velocities, choose a .243, or better yet, a 6XC or a 6mm-22-250. Compared to the full performance of the big case 6mm this leaves a lot of performance on the table and the key ingredient of a high velocity small bore rifle is high velocity.

Do you believe a longer barrel produces better accuracy than a shorter barrel?

My comment mentioning the 6mm-06 & 6mm-284 weren’t based on better performance. I understand that there’s barely enough fps to worry about between the three. The reason I suggested them was that if I wanted 240Weatherby performance, I would rather build a 6mm-06 than pay the ridiculous price for a weatherby rifle and exorbitant price of weatherby brass. The weatherby just doesn’t make sense from the standpoint of cost on performance return to me.

I get the argument, but a commercial rifle can be re-barreled for less money than a MK-V, then there's the Howa/Vangard rifles if they be found chambered in the cartridge you prefer. The cost of brass though, while at one time the best argument against the purchase of a Weatherby chambered rifle, is now in line with the brass we'd normally purchase with names like Lapua, Nosler, and Norma stamped on it. American bulk brass has become unaffordable due to the amount of prep time necessary to get it to shoot, the number of culled cases from new bags that occur, or the number of soft head occurrences resulting in extractor marks from moderate loads. I'll pay for quality brass when I can get it, and tolerate the other stuff when I can't. When I load now, I pay attention to the cost of the brass so I'm paying more attention to shoulder set back when I full length resize, I anneal my necks and shouolders, and swage primer pockets when they loosen, all aimed towards getting more releoads per case. I'm mostly playing devils advocate though in that I don't own any Weatherby chambered rifles, and on the occasion that I owned MK-V rifles, they weren't chambered for Weatherby cartridges; perhaps subconsciously I'm agreeing with you.

As a rule, shorter bull barrels are more accurate than long slimmer barrels.........you know, the harmonics/rigidity/density. There are many variables to accuracy, however to me personally, the barrel is the most important, stainless steel in particular. Canadians don't have to look very far for great barrels, we have them in our own country, and who I support through purchase.

This thread has me thinking about building another 6mm-06, but I know I will probably sell it again in favour of my 243 so I’m trying to convince myself not to.

One question will resume my taught: Whats the AMMO price for the 240?and the brass availibility ?

Brass for the 240 Wby. can be difficult to find, but it's around. Norma is the company who manufactures Weatherby ammunition and brass (as for as I know). Cost for brass you asked.......... NOT CHEAP!

In a sense these points you bring up are how my brain gets me to think if I need more 243 then step to 6mm-06 and skip the Bee. If I’m rebarreling a factory rifle to get to either round and both rounds have basically equal performance, than what’s the decision maker? Premium and expensive brass is a necessity for the weatherby, cheap brass can be bad for the 6mm-06, but as you mentioned it’s seldom worthwhile. However we can get premium 30-06,270,or 25-06 brass for quite a bit less than we’ll ever get the 240 brass for. Trip through Redding forming dies and off we go. Unfortunately for those of us who wrestle with inconsequential ballistic figures we can also do similar to make 240 brass I believe ha ha.

So at the end of the day it’s all just inconsequential Ballistic masturbation except for those of us who stay awake debating these things in our heads. Which I guess proves Tods point of “just get a 6mmCreedmoor and be done”, and if we want more velocity step up to a 25 or 6.5 cal. Ha ha ha

Another option might be to use a 7 Rem mag case, since they are plentiful and inexpensive, neck it down to 6mm, ream the neck to get rid of the donut, and get velocities that might push 4000 fps. Chamber you rifle with a Weatherby neck if you wanted to try it, and you'd fire form 6mm-257 Weatherby.
 
I DO not like wrongly head stamped Brass So for that reason i'm out on the 6mm-06 - I have a bunch of 240 WBee brass now as i have a WBee Vanguard in 240 . I do not shoot factory ammo for the most part and Weatherby has nothing loaded in what i would want for my 8 " twist rifle so i am hand loading only ! RJ

That's a 6mm Mach IV. Fast cartridge. - dan
 
I found the .240 very easy to load for and accurate.
