Well, I shot my first and only elk (CO) with a .260 140 gr. Corelokt at @ 150 yds. Bang flop.
On the other hand , about the 5th time I came through a screen of brush (locally - prior to the elk hunt)) to find 2 gallons of steaming brown bear crap, I decided the '06 with 180 grain bullets was not enough, so I upgraded to a .338WM , mostly with 250 gr bullets. The '06 always worked fine on moose....
It worked too.
In the 20+ (well- maybe 30-.... times arunning...) years since, I've never encountered another steaming pile of bear crap.
Bears a few times - but mostly when I was unarmed, or distant from the rifle....
Your current rifles are fine. Use the money elsewhere.
