With you on that.
I had a mint BSA Merlin - I doubt it had ever been used - it had been sold on here a few times. When I got it I fired a couple of shots but felt guilty in case I marked it.
It just sat amongst my collection - knowing I had it gave me no pleasure.
In the end I sold it on to someone who, I believe, just wanted a gun to shoot and didn't even know it was mint.
Sorry if any previous owners of it see this and think WTF but I really believe our guns should be used otherwise what's the point.
