12ga3” OO buck test group

Shot at 40y did t hit piece of paper. Moved in to 30y put three pellets on paper. Rem 870 20” smoothbore rifle sights. 12ga 3” OO buck.
That ain’t gunna get it done. Any thoughts please.

Use a slug?...
I am no help with buckshot

I might be forced to use slugs.

What choke are you using?
Try a longer barrel and an Extended choke.

Extended choke should help more the flush choke because of the longer taper in the extended choke allowing for tighter restriction.

Best luck with the pattern.

I've used Federal buckshot (12 pellet) with the flitecontrol wad and a mod choke screwed in my rifle sighted smoothbore barrel. Put the 12 pellets into a 12 x 12 INCH pattern/group at 30 yards. After that it started to open up and start to string out horizontally.

Buckshot should be banned

The OOD magazine just did an article on buckshot (I can't seem to find it though) with some pattern board info. There's a time and place for it.

I'm sure buckshot has it's place in killing things.... varmints maybe ? If you are going after deer I would only advise slugs or sabots. I have seen too many deer wounded because of buckshot and too much time wasted in tracking them. I have even shot deer that had buckshot in them from the year before.
Lots of good slug loads out there that won't drain your wallet. BTW when I say slugs I am talking about rifled slugs.

I'm a big fan of using slugs. Buckshot is too unpredictable for me.

Barrel is 20” smooth bore fixed improved cylinder choke
I guess it’s made for snugs not buckshot.
