I know Bob won't tune them,,, I think the only one he ever tuned was Genes (also a 1250), which is now proudly hanging on Shadows (Ed) gun wall.
Why don't you shoot it a bit and see if it smooths out some?? My .22 cal 1250 was never tuned and shoots very well, is extremely accurate and I can't even begin to describe how powerful it is

That gun is my small game powerhouse rifle !! Knocks the stuffings outa whatever critter it's aimed at.

Anyway,,, would be interesting to find out how many other Hunter Extremes are made in England. Keep us up to date on your progress with the rifle.....
