so i have made a fire former at work to turn 303 brass into 410 she!!s,
i have since found out this could be considered a handgun with a 5" barrel, i figured it was more like a ramset concrete nailer lol. anyway ill be welding a 19" long piece of 2" sch40 pipe over the exit hole to add a "barrel" so this is i guess a rifle hahahhah........... wait for pics, lol but as you know laws are laws

the chamber is a straight wall, its .462" dia, witch is minimum saami dia for the smallest part of a 410 chamber, so im sure it will chamber in all 410's then be fire formed to that gun when its used

as of now i shoot S&b fmj, just to get the cases to reload my cast bullets, ive used them for 25 reloads each now. lymans load data and also quickload put me around 16,000psi 880fps my chroni puts me at 910fps and i have a 4" longer barrel.

any way so after 25 reloads, they look and feel fine but im going to retire them into 410 she!!s and then used to load 8500psi once i get them made.
 
im going to use these in the 410 im making, i have bought a no1mk3 receiver and non matching bolt, so i plan to make the sear and spring, aswell as the trigger and stock, then fit or make a barrel (barrel would be 4140 1" dia for bolting up to receiver then id turn it down to a 1/8" wall with the .410" bore. chamber would be a straight .462" 56mm long with the 1.5mm counter bore for head space and rim thickness) basicily made to only dire the 303 convert brass,

i seen someone on here buy a crate of 410 musket ammo, now i wonder if there is a way to get that across the border and some sold to me haha..........

You have sure gone to a lot of trouble. I just take the .303 case, insert it in a wood block, and take a thousand of so off the case head with the disc sander, so my bolt will close on it. Then  I anneal the whole case, by turning it cherry red with a propane torch, and let it gradually cool. I then prime the case, load the it with about 6 grains of Unique, top the rest of the case up with Cream of Wheat, close it with a wax plug than fire it in my .410. If the low end of the case hasn't fully formed out, it will when you fire the first full charge in it. I usually use Berdan casings drilling out the primer pocket so it can take a shotshe!! primer. You have to go carefully so you don't over expand the primer hole, I usually use a hand reaming tool for the last little bit. The body of a .308 sizing die can be used to fold the case around in order to crimp it, watch you don't over crimp, you can get vertical fold which will damage the mouth of the brass, so it will tend to split.

i wouldn't say i have gone though any trouble, i personally dont have a 410 hand/long gun to form the cases with, and this was made at work with free material and i was paid during the time of making it. i guess i could have sat around and read the news paper if i wanted to have a bad day lol.

i know the method of forming cases, i plan on using 8gr w231 and cream of wheat. hot glue in the end with fully annealed cases. ill use my lathe and a nylon split bushing for drilling/reaming the primer hole to accept 209 primers.

the only crappy part is having to tighten the four bolts and loosen them back off. i may make a short barrel that threads into a lee enfield no1 receiver and use that to fire form the cases, just because its way faster to operate the bolt then those bolts

now making my own rods and pistons for my d16y8 engine was alot of trouble to save 800$ lol, next time ill buy the rods and pistons

dude i make sooo much crap hahah i have the habit of making it when board at work opposed to buying it.

im not sure if you noticed but ill also be making the 410 i fire these out of.

if you load with a shotgun/pistol powder like red dot or clays you can retain the rifle primers and reload with conventional dies ,

Hey, every one has got to have a hobby! The idea of converting a No.1 to shoot .410's sounds like a blast. You should ensure that the barrel is at least 18 1/2" to keep it from being "prohibited", so it can be used in the field.
