memtb,At 71 (in 6 days) …….substantially closer than just a decade ago, and it's also very terrain dependent!
If it's fairly flat terrain, pretty cool weather, and it's a nice bull…..about 2 miles would be my limit.
With rough terrain, a small bull or a cow…..exponentially less than two miles! If the terrain is bad enough…..about the same as my self-imposed shooting distance of 600 yards!
Oh and……grizzly population density also factors in! memtb
Looks like it is about Happy Birthday! Keep on trucking.
