Tried the Aguila mini-shotshells today in my Winchester 1300 with an 18" barrel. Had a couple of failures to chamber in the begining, but realized that I was cycling the rounds kinds gently. Once I started to use a little more speed (force), the next 14 rounds chambered with no problems. Shotgun is new, might be a little stiff, also. At 25 yds, had about an 18-24" pattern, 8-10" pattern at 15 yds. Not bad for an 18" barrel. Recoil is very light, like a .410. Not the cleanest load I have ever shot, but not bad. Had good penetration on an old 4"x4" piece of wood. Penetrated about 1/2" at 10 yds, don't know what kind of wood, but it didn't seem too soft. These would a pretty good home defense load, if they cycle thru your shotgun. If you try them, don't be afraid to use a little force (not excessive)to chamber the next rounds. They seem to work fine when you do. Hope this helps.
