It's unlikely that my Marlin GG will see use in our elk hunting area. Our area is mixed with timber and wide open spaces….so the 45-70 is not practical for "all around" use! If it is used…..I will be using my "homegrown" powder coated, cast (tempered), 430 grain, wide metplat bullets pushed to near 1900fps.
That's the only bullet (load) that I use in my GG, whether it be deer or larger game. A similar bullet and load, should give you "end to end" penetration on all but perhaps the largest bears, while creating a pretty decent path of destruction while in route!
By the way…….beautiful rifle! I'm a bit envious as I wanted SS, but settled for a large loop, blue, in laminate! memtb
