Just put a new 26 " Krieger barrel on my Tikka Tac. Put 30 rounds thru it today. Speed is 10 FPS faster than the 24" factory barrel. Will it pick up some thru more break in?
Yes it should. It might continue till you have anywhere from 50-100+ rounds. Every barrel is different
Plus it will seem faster since you had a Tikka, they are know to be a slow factory barrel.
