Took my new Supernova Tactical out to the Trap Range. Wow, that was great - did pretty well. Except for when the gun would jam trying to load the second round after pumping. At first, I thought it may have been user error (short stroking maybe?). But then I noticed it only seemed to happen with the Federal Lead 12 ga 7 1/2 birdshot shells. I didn't have any issues when shooting the Winchester shells. (both bought from Walmart) Anyone else notice this?
