240 wby

I am late to the 243 camp. Bought my first one last year, and let me tell you, it is VERY "cool" to me. :). But, what's up with ammo prices? Geesh
 
I've toyed with the idea of a 243ai I read the brass lasts much longer and brass can simply be fire formed where as the 240wby is just down right expensive. So far I've put off temptation of a fast 6 as I really don't need it. To be honest most of my coyote hunting is done now with shotguns. Also I don't have access to my old 1000 yard range anymore so my rifle shooting has been drastically reduced but every now and then it's sure tempting
 
I have 2-240 weatherby built on Remington 700 actions in HS precision varmit stocks. One has 28 inch 1:8 twist pacnor varmit contour and the other 26 inch carbon 6 sendero contour 1:8 twist and they both shoot incredible. The carbon fibre is awesome to carry and incredibly accurate. I built a 6-06 varmit remington 700 and shoots great too but the brass only lasts couple shots and seems to burn out from the inside just above the extractor groove and have pulled a couple bottoms of cases off with brass stuck in chamber and is no fun to get out. The 240 weatherby dosent seem to have the same issue

You are sizing your brass incorrectly or over pressure or both.
 
Well I’m resizing 25-06 brass so that’s not much of a difference so I don’t think it’s that. And I’m not running it hot so I’m not showing pressure signs. I don’t think I have one cause I Havnt shot it in a bit. But after about 3 loads the brass seems to be thin and washed out from the inside. It could be poor brass but I didn’t play with it after I built my 240 weatherbys. I can’t fix what’s not broken. Nothing worse than watching somethin run away with a brass stuck in the chamber

Blowing the cases apart is a pretty good pressure sign...
 
The problem with Weatherbys is that they were designed around old bullets and old tech. I have a 7mm Weatherby that was custom built in 1961. Now, with a 140gr cup and core bullet it will shoot damned well. But the 1-12" twist isn't anywhere close to the best twist in a 7mm for copper bullets or long (heavy bullets) that are in vogue today. A 168gr LRAB would be an amazing bullet in the 7 Weatherby if you were wanting to smack things from point blank out to 400 yards without touching your elevation dial. But the 12" twist and Weatherby freebore kicks you right in the tender meaty bits. Now, Weatherby might be spinning on 9" twist barrels these days (nope, 10" in the Accumark which is progress, I guess even though the custom builders are putting 9s on their 7mm barrels now) but I doubt that they have re-engineered their reamers which puts us right back where we started.

Granted, we're talking about the 240 Weatherby and not the 7mm, but the same limitation hold true. The bonus it has is that no one really gives a damn about anything 6mm (favouring the 6.5) so the average buyer is likely to overlook the fact that you get the same crappy 10" twist barrel in the Mark V Accumark in a 240 Weatherby that you get in the 243 at Canadian Tire. Good luck spinning a slippery bullet in the 105-115gr range fast enough to get it to make round holes in the target (or animal). Spin it at 7.5" or even 8" and it would have a very viable alternative to the 6.5 RPM (likely why the boys in Sheridan don't do that).

Wby reamers have changed over the years, as they have dialed back their freebore. Agree with the rest though. 7 wby is a great cartridge, that deserves a fast twist barrel. - dan
 
I'm really not sure what I gain or lose between 240 and 25-06. Both excellent deer chamberings, much more at close range. Again many calibers can say the same, without $3/brass. So same strengths and weaknesses, except basically one is a expensive, reloader caliber.

I like mine. Would I do it again, maybe.
