While I dont want to need to take the time to rack it, possibly short stroking, I also dont want to strike the primer too lightly and end up with a pi&&-poor excuse for a baseball bat...
If I was going to use a pump shotgun for home defense duty I'd load a snap cap, dry fire the shotgun , leaving the snap cap in the chamber and fill the mag tube with a 50 /50 mix of 1 oz breneke sabot slugs and 00Buck.
I use an old double barrel 10 gauge with 18.5 inch barrels w/ a spare 6 rounds in a sock and 2 x 00Buck rounds in the chambers. Got it a few years ago in a trade ,American Gun Co. Knickerbocker in very bad condition. Had it reworked, barrels cut back from damaged parts, refinished and restocked and it has been doing backup duty to my puppies Havoc, Chaos and Tenifer since.
