As said, if short action, go with the 358 or 338 Federal. If long, 35 Whelen. Of course, a good 200gr Partition in a 30.06 is a beast in its own right! However, I think just the project of making your rifle a switch-barrel would be a great experience and learning opportunity. Life is too short for "make do".
I had a little Browning BLR in 358 last year, but it was (a) expensive, yes and (b) did nothing my 35 Whelen Ackley Improved couldn't do, ha. I really like the 358, but my .35 Whelen AI has spoiled me. I've shot many elk sized plains game with 250X and later the 200X; from 30ft to 347 yards, it is a jewel.
I like the Barnes, but the magazine in the BLR required I used the 200TSX and not the Tipped version. No biggy, but a Barnes X of any kind is a humdinger in any elk round, IMO. I say go for it!
