chasing the lands...22 dasher

[n zeder]

after just over 500 rounds i remeasured coal and found f/b had grown 12 thou,reseated so projectile was back at 10thou into lands and accuracy was back to a ragged hole.
my question, is that excessive or just normal wear,i still have plenty of room so not worried just curious
specs are;true flight heavy match grade barrel
55gr sierra b/k
35gr 8208
3940 fps
before i reseated fps was 4040fps

That’s far from excessive and I would be very happy with that number! The 22 Dashers that I have had were usually greater than .005 movement per 100 rounds.
