I am just waiting to hear the penalty for shooting a 6 round snubby vs. a 5 round snubby
There is no penalty, per se.
But on the stage I mentioned, the 6-shot snubbies will have to shoot all 6, while the 5-shot snubbie will only have to fire 5.
Also, there is no "DRT" scoring allowed for 6 shot (or greater) snubs, which really isn't an advantage. "DRT" scoring is an effort to keep the 5-shot snubs competitive.
