Today I busted out my trusty Mossberg 590A1 and some loads I had worked up witht he Lee 1oz slug. Win AA hulls, CB 1138-12 (win 12R replacements) 44 gr of Blue dot, 2ea 20 ga nitro cards beneath the slug, win 209 primers. Accuracy wasn't as bad as I remembered.
However, the wads are toast. Seems like this tye of damage can't be good for ballistics. That's why I am wanting to try a new wad. Hence my other thread form today.
