barefooter56 said:If your rifle is a Remington factory rifle you will have to use their brass or have the chamber "touched up" with a 6BR LAPUA/Norma reamer. The big issue is the LAPUA and Norma being a little bigger in diameter down near the extractor groove of the cartridge case. This was done so they could put their name on the case head not Remington.
Also the 6BR Remington brass is sold with the primer installed and falls under the HAZ-MAT fee like powder and primers.
Take care,
