I am pretty sure the M1 is what qualifies in my mind for just plain ruggedness, a gun that will reliably shoot just about anything you put in it, and is not finicky if it is not thoroughly cleaned after each outing. As for weight, 9+ pounds for me = a "bag of hammers", however, I am sure there are after-market light-weight stocks like Ramline that would help that.
I have also looked at all the usual hunting grade suspects like the BAR and Rem 750, but they are "too much" hunting rifles for what I want. Also looked at the Saiga 308 with a hunting stock. While heavy the Saiga does meet my "ruggedness quotient", but it is not in 30-06.
I would like something that has really good barrel life too, so I can shoot it a lot, to get better than average with it.
I may just get a 30-06 single shot or budget bolt for the all-purpose gun and get a Mini-30, add a barrel strut and use that as the point and bang, bang, bang all day long rifle for reasonably big critters.
I appreciate everyone's help, keep new ones coming if you think I can benefit from your insights.
