Hi I've just bought a second hand nearly newTX200HC and the gun has only shot about 100 pellets. As it's been sitting for a few years I've stripped it and serviced it following the recommend lube.

I tested it and it's not pellet fussy but it's very close to the legal 12ftlb limit. There are three washers on the bottom of the spring guide can I just remove these to reduce the power or would reducing the spring be better ? Any help much appreciated
