There are lots of options, the M700 KS rifles are very nice and very accurate. I had one in 280 Rem. If you can find one in 7mm STW or 7mm RUM they would be very good choices for long range applications. So would the 300's.
I recently picked up a Tikka T3 Lite LH 270Win and it is outstanding. Anyways there are lots of choices out there, Tikka's are available in 270WSM and 300WSM too.
In the early 80's I wanted a 300 Mag, so I bought a Rem M700 BDL LH in 7mm Rem Mag and had it rebarreled to 300WBY.
There are lots of creative things that one can be done.
Yeah, the Tikka are an option, but they are very popular, so you cant pick up a cheap one as a doner action.
You can pick up a 2nd hand Rem for nz$800-900. You wont get a Tikka for under $1200.
Ok with a Rem, you have to have the action trued, and put a good custom barrel on. Does the Tikka action need trueing? and is the factory barrel good enough for a genuine 1/2" rifle.
If your wanting a Left Handed gun and have trouble getting them down there you might want to pick up a Left handed Savage action. With the Savage actions you can change your own barrels. All you need is a gun vice and a wrench for the barrel nut. You also need something to head space with which you can buy or make your own. Might be worth your looking into.
