Maybe up north where you're from.....Down here you can find more .300 WM and larger, and .338 anything on just about every used rack in almost every gun shop and pawn shop in my state.
The reason is, because they're overkill for us down here. Even my .300 Ackley is overkill for down here, but I wanted it, and it shoots great, and will make a great gun for, I would guess well over 1,500 yard shots??? You don't ever see anyone posting about having one other than 1K BR guys, but I'd like to know the capabilities of one beyond me skill-set, just for fun.
The most commonly used deer calibers down here are: 243, 308, 270, 30-06, 7mmRM, & 300 WM.
I think it would be cool to see an off-the-shelf (AFFORDABLE) .280 AI in the 40* SAMMI/Nosler chambering with a 26" 1:9 twist barrel offered in a magnum sporter contour, and a Rem Varmint contour.
Also a .25-06 AI 40* Shoulder with a 26" 1:10 Rem Varm barrel would be a sweet off-the-shelf rifle. Or atleast a regular .25-06, but ALSO offer the option to have one chambered in the AI version.
