This is a known thing reading the web. It seems they sometimes use milspec / harder primers.
I have had a few missfires. Brand new rifle.
First box ok, second box i had 3.
I then shot off a box and a half in one go out of paranoia without any problem.
2 boxes later i had a missfire, followed by the next 4 shots being ok. The ammo was bought Sept 23.
I’m not sure this is a gun or dirty bolt issue.
The only thing i’m seeing is reports seem to be from Tikka owners, which i also am. Coincidence due to Tikka popularity??
