Aye my middle finger is well out of practice too Tony

I used to have a Hatsan 60sc (or the poor mans hw80 for all you gun snobs ) it was a bloody great gun and one day I overheard one of the old lads at the range commenting that he hadn't seen anybody use that finger on the trigger for years.
After I realised he was talking about me I noticed that I had unconsciously switched fingers for a better feel (he he he )
so paying more attention to what I was doing and experimenting by forcing the use of the traditional trigger finger I found that my index finger was too strong and not as smooth and precise (if that makes sense) whereas the middle finger moved better with more feedback and I must have done this without even thinking about it.

Same with my thumb, some shots it will be up, some it will be over but I don't over think it I just let my body decide what's best for that shot
let's face it Im never going to win medals because I just enjoy sending the lead at the tin chickens and bantering with old and new friends.
