I am planning on forming some .410 cases from .303 brass. I want to load them with 93gr .395 dia balls. Have any of you ever done this? Can I safely load three 40 cal balls in this shell? Do I have to limit it to two?

A caution is that multiple lead balls may upset during initial acceleration to fit the larger bore diameter closer to the breech end just ahead of the forcing cone, and then may have trouble making it through a tight choke!
I cut the end of the burst muzzle off with a tubing cutter at 18-1/2", chamfered the edges, and installed a new bead sight. It makes a handy cylinder-bore snake gun now which throws skeet patterns and shoots .44-40 lead roundball loads into “minute of a bucket” at 25 yards.

I don't have any 44-40 brass. How do you think one .445 cal round-ball and 2.0gr Unique in a 44 mag case would do? I use it in a Win 94 to protect the “ranch” from outlaw gangs of empty soup cans.

I've been trying round ball in the 45-70. Unique has not worked well. I've quit shooting it for now, but when I get back I'm going to try Bullseye, probably in the 2-4gr range.
I bought 410 brass from GRAF supply. Not necessarily cheap, but a box of 25 ought to last me a long, long time. :fire ..........Dan

Hey Jim
What I have juked up is a 125 gr 9mm cast RN slug. The bullet goes inside the 410 wad down to where the splits begin. Cut the shell off to eliminate all the crimp portion. In my MEC grabber press I removed the shot and inserted the wad/bullet manually and seated them. If needed I can go weigh the powder charge or give you the bushing number used with 2400 powder. Even with a full choke barrel there is no bullet swaging and is accurate out to 75 yds or so. This was developed for a small young boy who was determined to go hunting with his Dad. This little fellow hasn't had the opportunity to shoot at a deer with the load but has gotten two turkeys so far. His firearm is a H&R topper, cut down to fit him. Bulleteering is fun.

Thanks Gunarea I might have to give that a try.
Dan I already load the 44mag case with a roundball. I use it in a model 94 and a model 29. I was wondering how it would work in a 410. I might give W-231 a try next. It might do better. I plan on fireforming 303 brass. I don't have much but like you said it ought to last a while. I don't know anybody that would want to buy less than twenty 303 cases.

.44 Mag rims are a bit thicker. If your gun will close on them they will work OK, but cases will bulge out and may split. A 2 gr. charge is a bit light. In the .44 Mag. I use 5 grs. of a fast burning powder similar to Bullseye with a rounaball. 5 grs. of Unique should work OK too.

I might fire-form those 303 cases and load them with the 5gr Unique loads, some wadding and one single 44 cal round ball. I'll also start loading 5gr in my 44 mag loads. Thanks Ed.

I just started messing around with the ballistic products small game slug load in my rossi .410 single shot. http://www.ballisticproducts.com/prodinfo.asp?number=0721641
The loads are in their slug loading manual,(which is not available right now, being updated). I got a copy of the page in the load manual from BP by e-mailing them.
Today, I tried a few in their multi hull 3” red plastic new shells. I used 2400 and some surplus wc-820. I also substituted for their .375 round ball with some home cast from a lee .395 round ball mold. I did try 5 of their .375 balls, they were all over an outers sight in target. The .395 balls grouped reasonably well at 25 yds, considering a simple bead front and no rear sight. Velocity is supposed to be 1320 fps. They have one load using longshot powder that puts that .375 ball out at 2335!
These are NOT multiple ball loads. My experience with multiple ball loads in several weapons has been dismal. I tried it in .357, found that the balls flattened and slug up to make a kind of wadcutter bullet. I couldn't even keep them on a standard target at 50 ft. indoors.
I also have some of the mag tech all brass .410 hulls. I'm going to try some of these round ball loads in them. Stay tuned!

Ed and Roy, I shared your posts with a fellow on another site. He got a kick out of the “minute of bucket". He said if it is a five gallon bucket he can relate. Roy he says he wants to give yours a try. He asked about the velocity. Did you chronograph the load? Thanks. Jim

Yeah, lid of a 5 gal. bucket is about right. Sut sometimes you get lucky for a few shots and think that you do better. But it's really just an illusion...

Hey Jim
We tried to chrono the load and did get a few readings right around 1750 fps. The wad might have been spreading though, cause we had mostly error readings. My chrono is a Pact, a buddy brought a Chrony out weeks later and got a better string showing 1670 to 1720. The Chrony also had many errors along with a 490 reading which threw all the averages off. We are way too lazy to write the good readings down and then try to extrapolate any of the averages. I promise to go write the MEC powder bushing number down.

I did some more work with the BP light game slug on Sunday. A surprise along the way!
The second pic is some of the multi hulls that were once fired, then primed with a WW 209 primer. The group size, location did not change, but the velocity sure did! Average 1877 FPS. Same powder charge, just a primer change.
None of this answers the OP's question, since this is a single ball load. And it is in plastic cases, not a re-formed 303 case. As I said, I do have some of the mag tech brass cases, I will try to load some of them in those. The wad colume is so long that I doubt there will be enough room, but I'll check it out.
This is in my Rossi single shot with a simple bead for sights. I have no doubt that actual front/rear sights would improve on the groups size. These were the lee .395 round balls, instead of the as supplied BP .375 balls.

Thanks for posting that. Apparently the 395's work good.

Those are good results for 25 yards and a bead sight. That's about what I got with mine. But I might try increasing the load after looking at your results.

I chronographed some Pakistani surplus .410 Mk.1 Ball cartridges out of the cylinder bore H&R .410 shotgun. Only four of ten rounds went off, and two of those hang-fired, but the velocities of those which went off was about 1600 fps.
A .395 ball weighs about 90-92 grains depending upon the alloy. I cast mine out of 1:30 tin/lead alloy from Roto Metals that I use in my .44-40s. The Pakistani rounds had 13 grains of a coarse flake powder, card wad, the case wadded with oakum and a .390 hard lead 87-grain ball crimped in the end.
I approximated the velocity of this load fairly closely using 18 grs. of #2400 in Magtech brass .410 cases, using a Walters .45 card over the powder, two Buffalo Arms wool felt wads, the top one being lightly lubricated with 30 weight motor oil and the excess squeezed out, then filling the case up to the mouth with granulated polystyrene grex filler to the case mouth, and crimping the ball in using a Lee .38-56 seater die cut off 1” by Erik at
The finished cartridge looks as good as the ones out of the Kirkee Arsenal in Poona... A .395 ball will go through most chokes, but you should slug yours before trying this.
