I do also agree that is a good price and well worth the price, the barrel count is fine, but just to correct, 6 mmBR accurate barrel life is 2500 -3000 certainly for shooting on tight targets such as 300 m and F class.
Also 6 mmBR shoots very well at 500 and 600 yds, my wife uses her spare 6 mmBR at 600 very successfully to practice wind, (and that's using our soft loaded 300 m loads), shoots flatter and handles wind very similar to 7.62 because the Ballistic Coefficient (BC) is better, and they will also go out to 1000 with no problems.
For 300 m use, the CISM has a 1500gm trigger, but the free trigger can be fitted, and the rifle shoots very well at 300 m (what its designed for), agree on ammo, factory Norma or Lapua is silly expensive, we reload top level ammo, works out about 60p a pop using 107 gn SIerra MK's.
Both you and Nick are welcome to come to the gb300m dates to shoot the real thing!
I'd have bought it at that price if I'd had a space on my ticket! So get it quick before I'm tempted to get a variation! I'm surprised its still there!
