I've always had the same opinion, the 6s have always seemed marginal as a deer caliber to me, but the only 25 that I've had was a 25-06. whereas I've had several 243s and a 6mm. They are common but the 25s are not. I've always wanted a souper, big enough bullets the be a little better on deer size critters, and gobs of 308 brass around, but I never wanted one enough to lay out the extra dough. Now with the 260 available I suppose I never will get a souper. Curious why the 25s never really caught on, kind of like the 35s never really making it either.
