I haven't YET tried the 80gr in 243 but I will be this coming season.
I do like light, fast bullets and I use the 110gr Barnes in my 7mm-08 Encore. It is sub-MOA accurate (it's a handgun, so it ain't easy) and the one deer I killed with it was a "Bang, FLOP!"
I expect the same from the 80gr 243. By most all accounts, they are a very good bullet, across the line.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
