    Anyone know how thick the neck of the brass was back about 1991 for a 6BR?
    Thanks

    Dave, the very first BR style Rifle I shot was chambered for 6BR using Remington Brass. This was in about 1993.
    The neck thickness averaged about .013 to .014 inch.The chamber had a .274 neck. I bought the rifle at a gun show with a couple of boxes of Remington 6BR brass.

    That Remington Brass varied as much as a full thousandth and a half as you measured the thickness in different spots.

    When Lapua came out with their 6BR brass around that same time, even with the necks turned to that thickness, it would not chamber because of the slightly larger web diameter.

    I donít know what the original Norma measured.

    Dave, I have some NOS Remington 6BR brass in the factory boxes.

    -The necks measure .014
    -At .200 ahead of the extractor groove, it's .4694-ish (depends how I hold my tongue ).

    Good shootin'. -Al
