Thread: Lapua vs Norma brass - your predictions ?

My 2c

Recently done some water capacity numbers for 6BR brass formed into Dasher -
Norma cases 40.45 cc
Lapua cases 41.54 cc
The Lapua case weight averaged about 6 grains lighter.
Loaded into Quickload it sees these values as significant differences.
Actual velocity tests with the same powder charge however still to be done to confirm calcs.
Then simply a matter of plugging into Shooter.
