Just looked at the 2019 1000 national listing.

1st place two gun was a 6BRI, but, second place was a .30

Top 6BR was 10th place and he outshot a lot of 6BRA and Dashers.

Small group for light gun was a 6.5CM

I'd hate to make definitive statements about which cartridge is better. Would the .30cal shooter have won if he had used a 6Dasher? Or should all the shooters who finished below 10th change to a 6BR cause that guy beat them?

Or will 'everyone' change to a 6BRI cause that one won in 2019?
