I have two cartridges of 30-06 multiball.
How knowledge if these are duplex or triplex ?
I observe a difference of weight of 12 grains :
- Left cartridge (W C C 5 8) : 434.2 grains
- Right cartridge (WRA 5 6) : 422.4 grains
The duplex use two projectiles of 96 grains (2x96=192), the triplex 3 projectiles of 60 grains (3x60=180) (“An Introduction to Collecting .30-06” article on IAA site).
One can deduct that the left cartridge is duplex and the right cartridge is triplex ?
