Largest cal rifle
On a lighter NOTE, I recently purchased a new in the box Ruger mdl 77 in .350 Rem mag. The rifle has great ergonomics, easy to carry and packs a real punch for any North American Game and is adequate for the BIG bears also. Jeff Cooper used this caliber to hunt everything with.
I bought it for bear over bait and maybe one day an Alaskan coastal bear hunt, but mainly because I have always wanted one. I plan to put a low power 1.5X5X32 Weaver Grand Slam scope on it and work up some loads it likes to eat and see what happens.
