one of the Trijicon LPVO’s or low 3x9x40 (or 42…I can’t remember) would be a dependable shot. Durability/reliability and 100% confidence in you scopes’ ability to always hold zero would be of primary importance hunting one of the most dangerous of all big game animals. From what I understand, a good first shot on these beasts and they are not too difficult to bag…an errant shot missing vitals due to scope losing zero and these monsters can seem bulletproof. The great bears can close distance perhaps faster than any other dangerous game when motivated by a wounding shot that missed vitals. Use a scope that has demonstrated a high level mechanical reliability and resiliency through drop tests, etc. Another option would be a lower mag range from SWFA’s offerings may be good candidates for hunting the big bears. Nightforce 3-10x42 is another.
