Ken, we should do what works for us & I am glad that you know what works for you & so do I. I don't even own a 4 wheeler. Ihave carried my Sendero all day(the 300WM) @ 9,500' & I carry my Sendero 25-06AI all day when hunting in WY. This is the first year I took a regular weight rifle in 270 & I did so just because I wanted to take some Mule Deer & Antelope with a 270, fortunatly that happened.
A 11 pound rifle is just as light for 1 guy as a 7 pound rifle is for another, there is no such thing as a weight that all must go by. I have a Mod70 featherwt. in 30-06AI & it is light, but it sees less use than my heavies, so to each his own. BTW, my younger brother borrowed
my 300WM in early Dec. to harvest an AR. Cow Elk. He has a Browning A Bolt, but wanted the stability of the extra weight.
So, as I said before I have no application for a WSSM, but I am glad some do. The more guns sold the better.
