240 Weatherby or 6mm-06?

[wbyfan1]

Think I'm finally ready to start building on an 8 twist Brux, 6mm barrel I've been sitting on for the last several months. Admittedly, I'm a total Weatherby fanboy and have been leaning towards the 240 from the beginning, but am now thinking about the 6-06. Only reason why is, I have a boat-load of 25-06 brass. From what I've read, all it takes is a pass through a 6-06 FL sizing die. No turning required. Seems easy enough. Seems the 6-06 has a skosh more perf as well.

Anyone here have experience with the 240 or 6-06? What kind of velocities can I expect with 105-107 grain bullets and a 26 in barrel? Please don't recommend the 6-284, as I'm not interested.


Thanks all.

My biggest reason to avoid the 240Wby is cost of ammo and brass. The 240Wby has a lot of fans but I would build the 6-06 because its different and it would be easy to get components for.

Just looked around on the 6-06 chambering and it seems easy enough to do and you will get right around the same Velocities as the 240 or a light higher from what I read. 3500fps with 100gr bullets and 4000fps with 87gr bullets is what I've read.

The practical choice would be the 6mm-06 but how many of us are practical I guess you need to decide if you would end up being disappointed if you don't get the 240 Wby which seems to be the one you really want, or flip a coin.

I think it is 6 and 1/2 dozen. Both have virtually the same powder capacity, and as long as you don't mind paying for WBY brass, there is no real loss. I'd kinda lean on the 6/06, as less expensive cases are always a good thing. Plus, I am thinking if it is set up right, it wouldn't take nothing to make cases from a 270 either..

It is a screamer and the 1/8 twist should be awesome on the heavy bullets..

 

[wbyfan1]

What about re-sale? Seems the 240 may be easier to sell.

I have no dog in this fight, however if I was to build one it would be with the 06 case. The 6 mm/06 has intrigued me for some time. Especially with long bullets.

I know you said you're not interested but at least you will get an idea of speed and accuracy if correctly built.

I have a 6mm-284 built on a 700/shilen/McMillan

90 gr AB at 3600 fps




4 shots




90 gr AB on antelope at 200 yds from a friend of mine

Why are you not interested in the 6-284?

 

[wbyfan1]

No question, the 6-284 has many attributes, but I'm concerned about the feeding issues many report, especially since this will be used as a hunting rifle. In addition, I already have a ton of 25-06 brass and also have a little 240 brass as well.

Re-sell yes. A good rule in all buying is to buy what you like and make it a keeper. I too would put my money in the .240Bee. Much more sexier cartridge and the last genuine Roy Weatherby cartridge. I would love to find a Crown Grade with 26" barrel in .240Wea.
What setup are you looking for??.

I think a 240 Wby has a lot of cool factor.

You aren't kidding Jim. Either of them, slinging a high BC 105 would be pretty sweet.. Twist it up right with a 1-8 to handle those long bullets and it would be a blast at the range. Run some 95 BT's, 90AB's or 100 PT's through it for hunting and man, you have a sweet handling deer rifle too..

Rem 700 Action

[FOTIS]

long heavy barrel?

If so I definitely recommend the vortex viper 6x20 I have on my 6mm-284

 

[George Foster]

Years back in the Modern Rifle Jim Carmichel wrote of running 30-06 cases into a Weatherby 240 resizing die and forming a belt on them. If this could be done it would be a good way of getting around the high cost of brass for the 240.

26 inch barrel. Brux #4 contour.

YUP ! X2 my Vote is 240 W Bee ! :grin: RJ

 

[Oldtrader3]

Like Rigby Mauser said: the .240 Weatherby has a lot of cachet. Plus being relatively low production by Weatherby. I would go with the .240 Bee all the way.

Not a 240 but will a 257 due?

That's a darn cool gun, Truck, but I already have a 257 Roy.
