Seen on all the barrels I have ever owned, the only difference being in how long they take to lead up.
Could it be these drastic changes in velocity are the reason for the inaccuracy after cleaning, maybe changes in harmonics ?

Cheers guys,
Had a thought earlier after I posted. Maybe a combo of the Baltic weather and the clean barrel would have caused the drop in power. May re-chrono tomorrow in the house and see if it improves.

I'd think it more likely to be the "sat in the cupboard for a few years unused" that's responsible for the power drop, than cleaning the barrel .
Guess you didn't read the full post bear.

Got to agree with the bear, reading your post suggest you chronod it a couple of years back, stuck it in a cupboard until you cleaned the barrel, took some shots and chronod it again very recently?
