The action is a NZ made Barnard action. I use a lot of these as they are a very rigid 3 lug action with a superb trigger available in several different sizes. In fact Kirby and I are working on a couple of projects based on his 338 AM at the moment using Barnards. They are available in the US from MT Guns. Yes, the stock is MacMillan. The barrel is a 30" Lilja 7mm chambered in 7mm/404 improved, pushing a 180gn Berger at 3400fps.
The supressor is custom built for me by Robbie Tiffen of www.gunworks.co.nz
who does a superb job.
My opinion on your 2 choice of chamberings, go the 7mm version. Velocity verses BC the 7mm beats the 30 in the same case size ballistically everytime. You'd need to step up in capacity with the 30 to equal the longrange ballistics of the 7mm/338L. If you want a heavier bullet for closer shots on big stuff the 30 will have the edge, but longrange, the 7mm does it with less powder and recoil.
