Can You Shoot .303 Brass Out of a .410 Shotgun

Mon May 01, 2022 7:09 am

i am looking to buy some contumely 303 cases and to blow them out for 410 use every bit i use a lot of 410 shells.

the question is naught to do with bravado thme out as thats been talked to expiry

what i want specific tiny details on is the convertion of the brass to standard shotgun primer use, so it stays legal to relaod with a uksg ticket

as far as i can run across i redrill the primer pocket add a primer holder on the inside and recess the instance to let for the primer to sit down flush

ok yep thats a very simple version of the events and then heres the tiny questions.
one, does chaanging from plastic to brass alter any details on the loading data?

ii, by drilling out the back of the case to acept the larger shotgun primer has whatever case issues ?

3, can i just reuse the primer holder from within normal .410 cases and reheat them back into place?

iv, what is the verbal hole size required for a friction fit on the primers and as i programme to ream subsequently drilling what sizes should i exist looking for?

why would information technology not be legal to reload with normal primers on a shotgun ticket?

you can prove you are reloading 303 cases to 410, and then need primers for 303 brass, so why would that be illegal?

Shotgun primers vary by manufacturer and then measure a batch before deciding on a hole diameter and examination a few every bit the hardness of the brass will vary by manufacturer. I personally form primer pockets as a tiresome operation on my brass. I have attached an image of an early on version of my 8 Bore case (Information technology has changed significantly in other areas since so!) I used CCI SG Primers and they worked well however I would still propose you experiment to determine the best diameter for your application.

For .410 I have only e'er loaded brass and my loads were finalised by experimenting and a blueprint plate.

Out of interest why can you lot not utilize rifle primers in a shotgun if y'all are using burglarize brass? You can or at least used to be able to buy the copper primer cups and I was even given some quite recently.

Y'all can purchase .410 contumely cases commercially, Magtech exercise them.

so first upward many cheers for the replies here a few pointers

i desire to go to shotgun primers as it is not immune to buy rifle primers with a shotgun ticket so to other people it has to exist shot gun primers fitted

yep y'all tin can buy magtech brass shells but not in the uk, the merely place i have ever heard of them being sold is Kranks or clay and game and neither carry tham anymore, likewise at £1 each and even so the requirement for the burglarize primers is there as well, so not availble , expensive and no primers makes it dorsum to foursquare one.

thanks ovenpaa for the info, reading the history books every one used contumely vanquish cases at i indicate but all the reloading data is for black powder its so old, modernistic powders are completely different so the brass and data dont friction match.

what i want to exercise is run a few dozen shells out in batches of 10 and then run them through brum proof house to compare results after that i can then decide on a gear up few styles that suits me best

Valmount Firearms advertise the Magtech contumely but they are £1 a example.

Ah, I see at present why you lot are not using burglarize primers. Any reason for putting them through the Proof house, do you take plans to sell the loaded contumely?

Even going from one brand of plastic hull to another brand of plastic hull itself can cause issue with load data.

Drilling the example caput to have the larger shotgun primer will weaken the brass.

I have heard of someone having a condition to their SGC to purchase burglarize primers for the loading of cartridges, but this could have been rubbish equally the VCR Deed is very specific. Drop your licensing dept an email.

no i dont its because i am a massive coward

i reload the .410 plastic shells att the time i have iii sets of information i employ, think of it as a brusk medium and biggest round i need.

in animal terms its rats, pigeons and rabbits or for me its rats clays and close pigeons. only i have never reloaded a brass example, so the data is slightly and it is slightly different, liking as i do the correct side of my face and being a coward ( did i mention that already !)
what i am going to do it to plow out 3 batches of four cases per given set of data with a slight adjustment to each one.

once i have had birmingham proof them i will know what to load and what best suits me and my shooting and then its full time reloading in contumely 410 for ever more

i accept been asked quite a few times if i am going to sell the empty modified brass cases though and whilst its a good i dea surely we accept to worry nearly come backs and legal beagles and and so forth reloading is a very touchy discipline

i did and he said yes,

due reason and all that and its ok, fifty-fifty my local gun dealer has agreed that its a reasonable request to say yeas to

what i desire to do is to look out for others to do the same as me so the total case refurbish is the route i desire to take so i can motion picture it and post information technology here for every one else to copy if they want
