The 410 shotgun was created using left over 303 British cases,straight walked to poke in cordite then sized down for 303. The 410 is just a 303 brit with straight walls..with me so far??? So what size lead ball would slot into said straight walked case?45 or 45?? Has it been done??? The 303 is a bit much for bailed pig and 410 a bit lacking.... Thinking inbetween case full of bp with powder coated ball.......
Interesting thought. If it’s in fact 45, how far from a 45/70 would it be? Or am I way off on that?
It's actually almost a dead ringer for the 444 marlin case straight out of the blocks. I recall wingman making brass cases for it.
Greetings @Micky Duck and all,
This has been done already in the 375 Flanged Nitro Express 21/2" from the late 1800's. The .303 case is smaller in the base than either of the 45-70 or the 444 Marlin so even with a reasonably straight case a .43" dia ball would be absolute max and .41" a more practical max. Even then the case would need to be blown out from its normal .401" shoulder. Just necking up would leave you at .375 ball dia. A bit less than you were hoping for Micky?
Regards Grandpamac.

Don't know if this will work but it seems this has come up before, on this forum even :thumbsup:

Without knowing the exact numbers I think you should keep max chamber pressures on your radar.
that is a good point. Would need to slowly work up the loadsQuote:

the other day on thread about stags with black powder it was mentioned a .45 ball is 180ish grains
buckshot is .30 or .32 calibre the plastic case easily and safely pushes out 3-5 of them 1200ish fps,in plastic wad.
a brass case that fits nicely inside a .410 chamber with round ball,maybe powder coated pushed down on top of load of black powder shouldnt create huge pressures,should be brown bess accurate in smooth bore say 4" at 25 yards as the goal..and might provide enough power without too much.....
WHY WOULD YOU???allowing a fella to carry the uber light rugged wee .410 shotgun but have a cartirdge on hand that will deal to animal at close range with a bit more authority than either the solids or buckshot..without the spread of buckshot
the mad scientist has returned from the lab
Egor my trusty assistant is now on half pay as ran out screaming halfway through proceedings.
learnings from the experiments
#1 jamming hand between die and hard surface hurts and causes blood blistering
#2 MRC .410 whackamole DOESNT resize the last 3/4" of a shell..bugger as that was my hope.
#3 the otherwise usless 3" long .410/12ga adaptors may have a use in resizing brass .410 shells (see darling the money wasnt wasted)
#4 a 45/70 case fails as cant quite get last 1/4" nearest rim to shrink inwards
#5 there IS a common enough size fishing sinker weighing 140ish grains that will resize to a nearly perfectly round .458 pill
#6 sometimes these things just need to stew away on back burner till all the bits fall into place
#7 half a dozen .444marlin cases would be really handy about now
#8 a very downloaded 444 case with usual .44 calibre projectile over load of black powder or using smokeless down load or trailboss may well be a hell of a lot easier and safer at end of day....
Micky, why 410?Quote:

Combined with a light to medium weight bullet for the calibre should do the job.
I’ve been having really good results with .395 hornady round balls x 3 put through an open choke or Enfield .410 “musket”. Am using a cork wad and powder weight based on the total weight of the balls.
Surprisingly accurate out to 100.
cause generally .410 single shot guns are lighter than a light thing to carry,and not uber expensive to get.Quote:

no because its opposite to above....heavy and uber expensive LOL
...and it doesn't put 3 hold in a target like the .410 with roundballs...Quote:

Ive heard of folks using a .357 projectile in the wee .410 too...
OK, I did wonder if it was Weight related. Fair enough.Quote:

Sounds to me the Lee .401 wad cutter would do provided it's doing 1250fps, no problem for a bailed pig.
Same goes for the .375 RB
Or this.
Greetings All,
Back in the 1960's a .410 shotgun appeared on the market. It had a 12' barrel and a pistol grip and was legal as a shotgun at the time. As it was a shotgun it did not need to be registered like our rifles needed to be. I briefly considered buying one at the price of $15.00 but dithered. Those sufficiently long in the tooth will remember these as Kea guns. A friend bought one and fired slugs at a steel plate around 2 to 3mm thick which it penetrated quite well. Shortly after that someone used one as a pistol so they were bought back by the Government and the law changed to require all firearms to be 30" long minimum. I think there was some exemption for pistol clubs.
Getting back to @Micky Duck quest for a light and low cost bail gun the cheapest option may be slug loads in the .410. Finding data and components could be tricky but not impossible. The working pressure for shotguns is very low and reliable load data for other options is non existent.
I can easily get solids for .410. But they are sucky...87 grns soft lead at 1500 fps...many folks used them and curse them.buckshot better option. It's no biggie,just seeing if there was a single projectile option ...may not ever have a use.ive got some 444m cases coming to try....
I'm also in unique situation of having an overboard 410. Same diameter from chamber to muzzle...gives options not available to normal .410 users
41 Magnum 200 grain cast lead wadcutters or semi wad cutters perhaps? The cylinder shape might help at least starting them straightQuote:
