I talked to a guy at Scheels the other day. I was buying a Nikon 2x scope for my Bisley 44 Mag Hunter. He told me his 454 trashed the Nikon scope in a week. He put a Leupold 4X on it and it trashed it in about a week. He was looking for something tougher yet. The 44 Mag is all I need for NA big game but I have a hankering for a 480 Ruger.
. If I need anything bigger, I will stay with the 308 Encore.
