Lead non-rifled slugs in a rifled barrel.

[Nickel Plated]

So I was thinking of getting another barrel for my shotgun to turn it into a half decent rifle. I only shoot it at the range, no hunting or anything. Shooting clays is fun but I figured letting loose some stout slugs once in a while would be interesting too.

So I was thinking of my options for some relatively accurate cheap plinking ammo.

For accuracy obviously a rifled barrel would be a great start.
Now usually the choice of projectile for rifled barrels is sabot slugs, but those are pricey as hell. Fine if you just shoot 4 or 5 out hunting. But blasting through 50 or 100 in a range session ain't gonna happen.

Using lead rifled slugs in a rifled barrel is pointless I hear. The fins on the slug mean there's not enough contact area to engage the barrel's rifling so you don't get any spin. Just get leading in your rifling.

I was thinking of casting some plain smooth lead slugs with no fins. So it would act like just a regular lead rifle or pistol bullet, just bigger. Would have the surface area to grip the rifling for accuracy and still be way cheaper than a sabot slug.

Anyone try that? Any opinions. Want to do some big-bore rifle shooting and figured an extra barrel for my pump gun is cheaper than a 45-70 lever action and the setup to load for it. Though that's on my wish list too.

Rifled slugs don't really "spin" the way you think they do. More like "stabalized" like a badmitton shuttlecock. You can shoot rifled slugs out of a rifled barrel but you're likely to get lead fouling so be prepared for lots of cleaning.

A few years ago, a member reported outstanding accuracy with home cast slugs (Lee mold) and a smooth barrel. I don't recall anyone commenting on a similar load in a rifled barrel. If you give it a try, please post your findings.

It sounds like an experiment worth trying.
The hassle might be figuring out the actual diameter of the slug that works best.
What are you going to use for a mold?

Lyman makes a mold for 12 gauge that is used with standard shot cups. The Lyman shotgun manual has loading data for it.

I didn't think they do. That's why I dislike the term "rifled slug" because it doesn't actually do what rifling in a gun is supposed to do. And the leading is why I'm asking for alternatives to the rifled slug.

I guess measure the diameter of a sabot slug with the sabot and a rifled slug at it's widest point and use that as a place to start.

As for molds. Try some of the commercial non-rifled slug molds.
Lyman actually makes a mold for a foster slug with no rifling. Seems like that's just what I'm looking for

Or perhaps the one jaguarxk120 mentioned. That uses a standard shot cup as the sabot.

Here's an interesting youtube page on home made slugs and molds:

IMO, the rifled slug in a rifled barrel are good to 75 yards.

The Lyman wad sabot slug to 100.

Real sabot slugs to 125 or so. This is with my 930 YMMV.
