Surprised no one has mentioned the 28 Nosler. Available in factory rifles, factory ammo, responds well to reloading. I have two friends with custom STW's. I had to tune each of them over the summer for an upcoming elk hunt (a couple of years ago). I was warned by the gunsmith that built them that the STW has a rep for being finiky.. He was right. It took me most of the summer to dial em in, but after that they behaved well. Accuracy was 1/2" or better consistently and velocities were right where advertised. One got a 341 bull, the other tagged a 343 bull.
It's a fine round, but now if you want that kind of performance, I'd probably lean towards a 28.
I agree. I also agree.....buy lots of brass.
