Before you buy a new rifle, consider building a bespoke one for less £££
There are plenty of older Sako actions being ignored in the UK's gun shops, they were made to the standard of many of the Gucci actions from the states, they're just unfashionable. The thread pitch means you can get a Tikka or Sako barrel or there are plenty of great gunsmiths who will fit you a barrel for sub a grand, the triggers are amazing, you can even get bottom metal to feed them from ACIS mags
50+ year old Sako L579 action, rebarreled to 6XC. I told James at Jagersporting in Ely I needed to shoot a 3 shot 25mm group at 300m using 100-115gr solids, in -11c weather.
Our friends in the US of A know how great these actions are, here they are almost for free. I lucked into a swap for the McMillan A5, but Wildcat Composites in Alberta are making great stocks for them for about the price of a secondhand McMillan.
It's going to wear a MINOX PRO ZP5 5-25x56 with the THLR reticle on a Near mfg rail, and an Gunwerks Elevate bipod.
