That's how I ended up with my 260 Rem, a barrel from a RH Tikka swapped over to a LH gun and love it. Super accurate. I'm saving the 300 WSM barrel for when the 6.8 barrel gets burned up.The 6.5PRC barrel I'll be using is a factory take off. I've had great luck with Tikka barrels, and try to use them when available in the twist I'm looking for.
I've used the MT long action Billet Mag for short magnums, and function has been flawless. I run them with a long action bolt stop. That set up will yield all the COAL you can use in a short mag. The OEM long action mags might also work well, but as I think about it, I can't recall ever running them with short mags.
I'm running a 7mm RM in a Tikka with 3.715 AICS mags. Functions flawlessly, but I'm not the biggest fan of the mag hanging down on a rifle that gets carried in hand a lot. Would be nice if someone would offer a near flush mount, long action AICS. I know there used to be some available, but they appear to be discontinued.
I was leery about that long action MT magazine for a short mag but it seems a few guys are running them with no issues. The standard long action OEM mag from my wife's Tikka 6.5x55 is too narrow inside for the fat WSM rounds as is. I have read that people have used a dremel tool on the inside to give it a bit more room to make it work. I would personally just go with the Mountain Tactical magazine first.
MDT has a 3 round WSM magazine that might sit flush but it looks like they only offer 5 round and 10 round for the belted magnums.
