Newly joined MossbergOwners.com, but read many of the posts here and on other sites. I've read extensively on recommendations for HD buckshot, but I'm interested if anyone has had or knows someone who has had HD/Law Enforcement/Military experience using buckshot other than 00 in an actual deadly force encounter? I load my HD 590A1 with a mix of #4 and 00, but just bought today some #1 and 000 which I plan on trying out on the range this weekend, but shooting paper targets is nothing like the real thing. If anyone can share some insight I'd be grateful.
