I didn't check with the Leica. I got to caught up in shooting and then just used the BR2. Never ranged anything further than 500 yards with the Leica today. This BR2 is about 4 times the size of the Leica but not a lot heavier.
I am going to compare them at longer distances maybe tomorrow night- have to work in the AM.
Wonder how they got away with using the name "BR2" without violating CCI's copy write on the the primers???
