Using Omega with 3-9x40 Bushnell Elite scope, 2x50 grain 777 pellets pushing a 300 grain Hornady SST.
Didn't really need the scope, since I took him at 30 yards

The SST went in exactly where I put the crosshair.
I was baiting a bear with donuts, sitting on the ground behind some log, and this

guy showed up instead and started to eat the donuts. I couldn't have that !!!
He was quartering towards, so I shot him in his right chest. Small entry hole, no exit. Didn't find bullet, so I asked the butcher to hold on to it if he finds it. Very little blood trail, but didn't need to track - he fell over 15 yards from the spot, after running back and forth and smashing his head against the trees so hard he shed both antlers (he was a 7 pointer by the way).
Thank you everyone on this board for the very helpful information !
