RE: why is weatherby ammo so expensive?
My 340 is a Mark V Stainless Synthetic with an Accubrake, I believe the barrel is 26" plus the brake (Its long). My first gun was a 338 Win Mag and the kick is allot less, atleast to me, I really don't know the real numbers. But it is louder and now I'm getting alittle concerned about hearing so I always wear ear protection even when hunting. Originally I wasn't going to buy it because I already had a 338, but it was too good a deal to pass up used. I think I paid somewhere around $1000 CDN ($650 US) for the used gun, with a Leupold Vari-X III 1.75-6x32 scope and a full box of weatherby shells. Up here in Canada Weatherby Ammo is a premium and hard to find (atleast in Eastern Canada, its readily available out West), so whenever I do find some I buy it even if I don't need it. I must have 8 boxes now.
Having used the gun now for 4 hunting seasons, I can say this, its a little long on the barrel for me, I'd prefer a shorter rifle to carry and handle. I also prefer a detachable mag that the weatherby does not have. Positives it shoots great, its accurate and I enjoy shooting it, more than my 338.
If I was to look at buying one today, I probably woundn't own it. Just because its an oddball for ammo and the gun is long on the carry. Because I prefer the detachable mag the UltraMags wouldn't be a good choice either (I was real close to buying one recently but didn't want a Browning, very close to buying a Rem Sendero or the Sako but both had a floor plate). Instead I bought a Sauer 90 in 300WbyMag (I found another deal that I couldn't pass up), ammo is easier to find, ballistically a very good caliber, detachable mag. I haven't shot it yet but plan on using it this fall.
When I get tired of that who knows, maybe back to the Ultramag or just a reliable time tested 300 Win Mag.
Not a great response for someone who calls himself 340, but I'm just being honest. If its a good deal, go for it, you can always sell it later if you don't like it.
