I guess if im hunting where it doesnt matter then a normal 2506 will do just fine and if im hunting where every little advantage is real then i want the faster of the bunch. Im not saying the AI is a waste. It certianly a viable long range gun. But like i said i can at least recoup my money back out of a weatherby. Rechamber something like a rem 700 or a win 70 to AI and it makes it worth less then the gun originaly was worth. At least where i live. I guess everyone has there own thoughts on this and probably no one is wrong here.
I don't look at it in terms of selling guns and recooping my money, because I don't sell guns. I've sold 2 guns in my life, because I had to have money THAT day, to pay bills. But other than that, I don't sell guns, because most of mine are bolt-actions and they can be easily converted into something else with a simple rebarrel.
Yes, 10 gr of powder isn't much, but 10 grains is 10 grains. That's only 10 fps gained per grain of powder. That's not much.
As far as which cartridge is better, I would have to say being they are similar in velocity, it's a toss-up. But as far as efficiency and cheaper to load for, the .25-06 AI gets that award. Plus, you can buy .270 Win brass for pennies on the dollar, compared to $3.00 a pop for new .257 Wby brass. Which is why I shot factory ammo first, and gathered up plety of brass before reloading. At the time I started shooting my .257 Wby (2008), 20 pcs of new brass was about $10 cheaper than just buying factory loaded Wby 110 Accubond ammo. So I bought the factory loaded stuff.
Now that I have a nice brass supply, I don't count brass into my reloading equation. So the only difference for me is 10 grains of powder, and 210M vs 215M primers. And primers cost the same at my local GS.
But I still look at it from a logical standpoint. The .257 Wby does have significantly more recoil, muzzle blast, and shorter throat life than the .25-06 AI. Those are proven facts. How much shorter throat life, I don't know. But I do know when you factor in 10-15 more grains of powder that's alot more burn time, which means more flame on the throat. Therefore tha will decrease throat life.
