Hi Clarky
Thank you for the clarification. You are, however, in a privileged situation in that you are able to modify your rifle and have the inherent ability to shoot it at a high level such that shooting is not as much a challenge as it is to someone with far less experience and shooting a standard production rifle that has had no work done on it. So, maybe I put it rather wrongly in my first post: it may not be a challenge to you but it will be to far less gifted shooters. And I suggest that even with a highly tuned rifle, springer shooting is still a challenge to the majority.
And if people wish to spend cash on their hobby and buy all sorts of equipment to aid their shooting (and I include rifle tunes here) and hopefully improve their performance, why not? I too have seen shooters with very expensive FT PCP rigs who missed a big 25yd kill even after spending ages fiddling with range finding and scope fiddling. But hey ... they were having fun in their chosen sport.
Cheers, Phil
