As already mentioned, we cannot bait bears in BC, but when I was across the border in Alberta it is allowed.
Never did end up sitting in a stand over bait though.
Over the years I have taken more bears with my Marlin in 375 Win (6), but have alo used the 30-30, 338-06, 300 WSM, and 338 Win Mag. I have used my BLR in 358 Win with a VX-III 1.5-5x20 frequently when backing up others bear hunting, and assisting when trailing wounded bears. Another great choice! (Just haven't shot a bear of my own with it)
The 375 Win with 200 or 220 gr bullets @ 2200 fps works very well on bears!
Open sights are great for short range work, but as we get older, our eyes may not resolve the irons as thy once did, and a low power scope or red dot may be a better option.
My 375 wore a Leupold M8 2.5 scope w/ heavy duplex for years, and was capable of producing 1" groups @ 100 yards.
I have now put a VX-R 2-7 on my rifle and that illuminated reticle will show up against that black hide in low light or dark timber!
