REALLY bad patterns with buckshot

k77/22rp · September 10, 2001, 08:02 PM

Hey,
I was shooting my new mossberg 500c 20ga with rifled slug barrel and I was getting good groups with remington sabot slugs
but when i tried shooting buckshot at about 30 yards I was getting TERRIBLE patterns. They were going into the dirt about 15 yards downrange

Aiming about 4 inches high they were still going into the dirt! The buckshot was Federal 2's

I know it wasnt me because the same was happening with my dad and he is a great shot, so is it the load (i hope) or the gun?
thanks

You can't get a "pattern" shooting buckshot through a rifled barrel.

Rifled barrels are good for nothing but slugs. 'Learned that the expensive way. 'Dealer sold me an 870 Deer Gun (rifled barrel) with the assurance that it would be good for HD with buckshot. 'Had to buy a smooth bore barrel after testing the rifled barrel with buckshot.

Like Tyro said.

Rifling imparts spin to the projectile....which stabilizes the projectile as long as the projectile doesn't fly apart from the spinning. Slug stays together and performs just like a bullet from a rifle. Shot column flys apart from the spin.....hence giving a higher meaning to the term "scattergun".

The best patterns I have had with my recent buckshot loads were while using a loooong steel modified choke tube. I would suggest that any modified or full tube built for heavy shot loads or steel would pattern well with buckshot. Try using your regular choked barrel and save the rifled barrel for slugs.

Thanks, now that i think about it, that makes sense.

The upside of your situation(if you want to call it that), is you can get a pretty inexpensive smoothbore barrel if you want to have this shotgun do double duty.

I own a several shotguns but my "universal" SG is an older 870 12g 20" rifle sighted barrel with rifled choke tube for the deer season only that gets switched to a modified choke tube for the rest of the year. It sees duty as HD, varmint/pest control around the farm, and still keeps the freezer stocked with venison.
