I replicate old Webley and BSA targets, purely for my own use, and to provide a bit of "dressing" to go in the maker's boxes.
I've found that you can only really appreciate what level of accuracy the manufacturers were trying to acheive if you shoot their guns at the targets they supplied as accessories.
Shooting Webley Pistols at their No1 6 yard pistol target, at 6 yards, is "too easy", but go up a step in distance to 10m on ISU 10m targets, and it's a whole new ball game with a Webley pistol. It's doable, but lapses in technique are instantly punished.
The South of England has 2 good things, the M1 and the A1. Both will take you to Yorkshire.
