I just purchased a Super Black Eagle 2 with the synthetic comfortech stock. I will have to wait to days to pick it up because im in Cali. Should I break it in with some 3.5" magnums to help it out with lighter loads for skeet? Also, if I want to add a magazine extension, which brand is the best to get? Are there any other upgrades I should look into, such as an aftermarket follower? thanks in advance
