Sunday morning and early afternoon was spent entirely on the 50m range breaking in the barrel; shoot one, clean it, etc... Very pleased to report that there are no feed or extraction issues with any of the ammo I used which included steel jacket Barnaul (bought from Dave at Shooting Shed

After approx 80 rounds of fun, sorry I mean laborious breaking in, the grouping was certainly getting tighter and my ears were starting to bleed; that muzzle brake is a beast and on a firing point with walls either side the shock wave was something to behold.
Anyway, here are some truly awful pictures taken on my phone as my camera has decided to throw a wobbly.
