Re: Canvas cheek piece with pouch supplier?
I prefer the Eagle model as well.
FWIW, a lot of guys have mentioned that the Blackhawk "Hawk-Tex" cheekpad is a little "sticky" and not as comfy to shoot for long periods of time.
Wildcat, the shell loops will take .300WinMag, but they're tight enough - you'll be pushing it to get your .408s into it. The good news is that is really isn't that practical to carry ammo there anyway, especially long ammo.
The beatings will continue until morale improves.
