who hear actually thinks hornady tap ammo is any more necessary then bulk remington 00 buck?
It depends on what someone want to get out of their gun. If moderate sized patterns at typical across the room ranges will meet your defensive needs, then any good 00 buck load that runs in the gun will do fine.
But if you might need to s t r e t c h out your buckshot range some- out to 75 feet or a bit more- then you want a tighter patterning load. And since few defensive size barrels (18- 20") have either factory fixed MOD chokes or are fitted with choke tubes, the only way to try and get good tight patterns at longer range is to use premium buckshot.
It just depends on what a given shooter needs to get out of their gun, one size DOES NOT fit all.
