My 3-4 year old BSA developed an air leak recently.
rather than look at a reg change and strip/re build
I opted to get John Bowkett to do his Blueprint and bolt mod,

the Rifle was always as I thought accurate
but upon return the difference is night and day.

bolt action precise accuracy first class I am over the moon with the gun again and it is perfect for my use with Rats and rabbits.

the total cost was £230 for the work and as a reg is nigh on £100 I think great VFM.

just waiting on some more pellets as I have bisley and the proof sheet John supplied showed JSB heavy even more accurate
