There isn't a bear walking in NYS that can stand a 80gr Barnes TTSX in the boiler room or shoulder. All I've killed with the .243 and that load are deer in NY and PA but all have been one shot kills.........
That said, today I took a few pokes with my 300WSM and it shoots lights out like all my guns. I only have 17 bullets (handloads) left for it but that should get me through Opening day if I choose to carry it and I just might.
