Round ball in a 20 gauge


Registered Users do not see the above ad.


Anyone here ever load a round ball in a 20 gauge to use as a slug. I took an H&R 20 gauge,cut the barrell back to 20 inches, put on an ATI stock and forearm,Put on a heat shield and a fake flash suppressor for my 15 year old son. He's costing me an arm and a leg just to buy shot to keep ammo reloaded for him.I have plenty of lead so I thought I would reload with a round ball if this is possible. What size ball should I use. I would like to reload with the ball in the wad. I was thinking probably either a .570 or .575 round ball.
I know these probably would not be super accurate but we shoot at steel gongs that are 12 inches square so that would be accurate enough.any advice and suggested load data would be appreciated. Wire Nut

You might do search on 20 gauge slug loads. James Gates has posted a bunch on shooting heavy cast loads in both the 20 gauge and 12 gauge. He's doing some really interesting work on big game shotgun loads. Check out some of his posts also.

We have a short range deer season here in this part of Idaho and I've both a 20 gauge and 12 gauge shotgun that I'm going to run some of his tri-ball loads thru to see what kind of accuracy I can get for that season next year. My only problem is I need a new barrel for my Mossberg 835. The instructions says not to use slugs in this over bored 12 gauge barrel.

Round balls? Interesting! Hard cast round balls in shotgun bore size has been around forever. Frank Forester, in 1838, traveled and hunting all over the USA with a .60" (cal) rifle and put down about everything! The normal bore of the 20 runs about .625",
The problem comes with the fast twiat in these modern guns! Much too fast for ball except at very slow velocity. You might want to try an undersize ball in a plastic wad.......or find/buy a mold.
Regards, James

Lee makes a slug mold for use in a standard plastic wad, but it's not a round ball, but a hollow based keyed slug designed to be loaded in a standard shotgun shell loader. I'm thinking about getting a standard rifled barrel for my mossy for slug usage and putting some of James heavy duty ammo thru it for our short range season next fall given I'm still around and kicking. Perhaps with the old aimpoint I might be able to use it to a hundred yards.

I just got a .562 round ball mold.I plan on loading with the ball in the wad.I measured the petals on the wads I have and they measure about .020" of an inch.The barrell at the muzzle where I cut it off mesures .615 of an inch. The .562 ball may be a tad small but I am going to try it anyway. As long as knothead ( my son) can hit a 12 inch gong at 50 or 75 feet he will be happy. Thanks for the info and any other will be appreciated. Wire nut

Maybe some of the older guys will remember the little single shot foldinging shots guns, mine was a Beretta but were marked under several names. Got a 20ga.very cheap as something truely nasty had rusted the last few inches of barrel (best guess is that something corrosive had gotten onto and into the bore). Ended up as a 21" no-choke and I added a set of rifle sights.

Was wonderfully accurate with RWS slugs, but for practice and gooding around, tried round ball.

Like you, started with regular shot cups. Unlike you, wasn't going to try smokeless powder...shotguns are a bit "twitchy" about component changes....so used black powder. Some of what I found might apply.

Shot cups come in different thicknesses...some for steel, some for lead, but there seems a wide variety.

The ball will seat deeply in most cups...too deeply in most, but today there might be some wads for very light loads that might be better.. With BP, I just added fiber wads between the cup and the charge, cut the shot cup's pedals down, and got everything to end up nice and tight when crimped (used a standard star crimp).

Accuracy got a bit better with a little granulated poly UNDER the ball...believe it helped the ball conform to the bottom of the shot cup without deforming at ignition. Guess you could use the same stuff to build up the ball in the cup so it ends up near the top and crimps nice and evenly, but i haven't tried that.

Overbore Mossberg & Slugs.

faucettb:

Mossberg's warning is aimed at conventional foster type soft lead hollow based slugs in the 10 gauge size overbore barrel. The overbore may let high pressure gas into the hollow hollow base causing the thin lead sidewalls to separate from the heavier nose of the slug. Then the wads would blow past the lead ring leaving a bore obstruction. Bad news when the next shot is fired!

Dixie Tri-Ball loads then will fire safely in overbore barrels like any charge of shot.

i think a .58 conical in a csd wadcup from bpi is the way to go. or load a round ball into one and youve got a nose heavy self stabilizing slug. the wadcups are cheap, and round balls are cheap. youd have to figure your diameter out but id guess .574 to .577. i get heavy super hollow hollowpoints of around .580 and turn them around and put them in the csd wadcup to make them hollowbase slugs. work great in smoothbore with reg. or black powder. mr hollowpoint has a lot of cool bullets. 650 grains of soft lead will really make that metal plate ring.

Not a 20, but I have loaded a 690 round ball in a 12 with good results. Turns out the ball weighs the same as a charge of shot 1 1/8 oz. I needed to load half of a fiber wad under the ball to make it crimp tight, but it worked fine in a plastic shot cup. Good luck!

The results with round ball in a conventional shot cup wad can compare very well with all those ingenious slug designs, although we do hear some pretty extreme claims for the latter online. Accuracy should be best with a cylinder or improved cylinder barrel.

What is most important, though, is that the ball is of the right diameter to make the cup wad fit closely in the bore, and to be poked though the choke with a cleaning rod, if you have any choke, with little resistance. With this proviso some choke shouldn't be dangerous. A true 20ga. should be .615 bore, and is unlikely to be very different in modern or nearly modern guns, but with old ones it might be.

A cheap single shot gun is probably best for this work - better than a double, for sure, and probably better than any repeater with the barrel held by the magazine cap, like my Winchester 1200. If I wanted a specialized gun for the purpose, I would look for a Greener GP, which is a slightly oversized Martini in 12ga., with a clamping screw on the threads of the detachable barrel. There are a few 20ga. shotguns around which were produced by the conversion of military Martinis.

Soft or hard lead makes no real difference in this application, on gongs or game. The star crimp is far better than the old wad and turnover, or indeed any packing between ball and crimp. In the old days barrels were sometimes bulged if that wad got between ball and bore. It is best to position the ball with wadding behind it in the cup wad, so that it doesn't move lengthwise in the case. If it is brought right to the front, a turnover exposing the front of the ball should work fine.

A cheap single shot gun should be best for this work - certainly better than a double, and probably than a repeater in which the barrel is held in place by the magazine nut like a Winchester 1200 I used to have. If I wnted a specialist slug gun I would look for a Greener GP, a slightly oversized 12ga. Martini action which is capable of standing considerably higher than normal shotgun loads, and in which a clamping screw tightens up the threads on the detachable barrel. There were also some 20ga conversions of the military Martini-Henry, which ought to be cheap.

I load .615 round balls in brass 20 ga shells and they shoot quite well. I also shoot a black powder flintlock I .62 or 20 ga so I have s good supply of round 20 ga balls.

That should work, but wouldn't leave space for the shot sleeve of a plastic wad. Some form of dry tumble lube might help to avoid lead smearing on the bore.

I cast .715 RBs in pure lead and load them atop brush wads and gas seals from BPI. They shoot nicely in smooth bores out to 50 yds.
No reason that you could not do the same kind of thing with a .610-.615 RB.

.713 is .016in. under the standard 12ga bore, and I am not sure if you surround it with any kind of sleeve. But .615 is the standard 20ga., with no room for anything but the naked ball. That could allow the ball to roll on the bore surface, which is a source of inaccuracy.

I would also be wary of having the sprue untrimmed, if the ball isn't held snugly in a sleeved wad. If the ball rolls over that sleeve, it could act as a slight bore obstruction. In the days when sheet metal anvils were occasionally blown through the flash hole, they could cause a dimple in the bore when the next shot ran over them.
