Thread: Tikka T3 .270 COL reading .005" off standard COL

Greetings,
Personally I would not put Loctite anywhere near a rifles chamber, just asking for trouble in my opinion. The other problem with the close on chamber method is that with full length sized cases in most rifles the case will be pushed right to the front of the chamber as the extractor rides over the rim giving you a false reading. Small differences in COA length make little difference to accuracy unless the projectile touches the rifling on chambering with some rounds and not others. Winding the stem down 0.5mm further for a 0.5mm shorter COA would not be a bad idea, pretty much what @Micky Duck said.
