    barrel thread (tenon) size database

    is there one for modern makes?

    found this for older ones:

    just wondering if all Tikka and Sako models are different

    A recent re barrel job has thrown up an anomaly, with my Sako Finnbear .270, being an unexpected size.

    I don't know if it's what you are looking for but I thought it may be of interest.

    Unfortunately there seems to be quite alot of various anomalies with tenon size and threads from one action to another. Makes life so much easier if you have the old barrel to measure off. Not meant in a pee taking manor. But measure twice cut once as the saying goes.

    Sako and Tikka threads seam to come in at average .995" x 16 TPI some as low as .992", should they be 1.000"? dont know but if they are they are out of CIP spec.
