I think the fun in this hobby is that a "tune" can mean different things to different people and could mean different things to the same person depending on what they want. I have a few tuned rifles by guys who know what they are doing. But I like tinkering with them myself too. Some for power, some for smoothness, etc. Sometimes those qualities are just relative. I have tuned a rifle which in the end still was not as good as another but relative to where it started I deemed it successful. And if I think it has more to give I don't mind tinkering with it more (sometimes I even prove "less is more" LOL) Geez, I'm not sure where I'm going with this but to say I can appreciate them all for what they are and what they bring to me which is a sense of appreciation and fun.
