First off, welcome to the forum... nice to have you here.

Depending on where you live and what kind of shots you might experience, could make a big difference. Are you allowed to scope the rifle? Can you shoot sabots or only conicals?

Both of them are quality rifles with quality companies behind them. Both are going to last you a life time. Right now there is a powder on the market called Blackhorn 209 which seemed to be very much in demand by many. BUT it takes certain rifles to shoot it. The Triumph with the new powder is puttting some very impressive groups, with a Scoped rifle even out to 200 yards.

I do not own either. I have heard that the KRB is hard to get behind for shooting open sights. If you are going to scope the rifle, either will do the job just fine.

I like the looks of the KRB better then the Triumph but it is hard to argue the way these T/C rifles are shooting....
