I've measured new Lapua 6BR, and new Alpha Dasher/6BRA brass......all he same length.I was referring to the case lengths on the reamer prints we use at JGS for the 6 Dashers.
Our #1300 print for the 6 Dasher (meant to be used with Lapua brass) is 1.570, the Dasher Norma #1318 is 1.605, and the 6 A-TEAM print (Alpha brass) is 1.555.
As always, especially with Dashers, as there is no standard, we suggest measuring your actual brass or sending in a dummy round for us to measure to take the guess work out of it.
