I wouldn't spend any money on a new rifle, unless it is too heavy for you to lug around. In my 30s I walked around for hours with a Garand hunting moose. As heavy as that is, it is still lighter than my H&R 12 GA Slugger and comparible to my T/C Encore muzzleloader which I continue to carry...
Never mind, I read through everything and saw what scope he uses. He can shim the scope when he mounts it to better enable him to use the whole 110 minutes of travel, but I don't that should be necessary. Using M-118LR I have to come up about 50 minutes when going from 100 yards to 1,000 yards.
What scope is he using? I have the Hi-Lux XTC1-4X34 Service Rifle Competition Rifle Scope on my M-1A for 1,000 yard service rifle matches, and that's without using a 20MOA base. Prior to that, I just used the iron sights. Same with the Garand.
I have not been able to test it on actual game, but I bought some for my Savage 300 Win Mag. Sighting in at 100 yds, I got a 1/2 inch group. I live/hunt in MD, so I can't use that rifle for deer hunting. I bought it for moose hunting in Maine, just haven't been selected in their lottery yet.
