Reloading blown out .303 -410

[Gazza]

A few more questions.....

I'm planning on blowing out some .303 cases to reload for the .410 shotgun.

Question 1.. Do the cases need full length annealing before blowing out?

Question 2.. Is it legal to use rifle primers in these cases when fired from a section 2 shotgun? (I have centrefire rifles on my FAC so can legally buy these primers)

Question 3.. Are there any extraction problems when using blown out .303 cases in a .410?

Last question.... what size of charge should I use to blow the cases?

The first link is very informative, I had no idea such a thing was possible.

No Issues with rifle primers and it is also possible to modify the 303 brass to accept shotgun primers

Are you trying to load for a Lee Enfield 410 Indian Musket or for a 410 shotgun?

Clay and Game stock 410 Magtech Brass if you are looking for the latter

They are for a .410 shotgun.
I've seen the magtech ones and thought the 303 route may have been cheaper but with all things considered this might not be the case.
I watched a couple of youtube videos after posting my question and the blowing out seems to be a bit hit and miss with some cases breaking and some deforming. At the very best its taking 3 fires to form them right it seems.
Further investigation and costings required
Thanks for the links, I'm off for a read

Pun intended?

A friend of mine has fireformed .303 HXP brass into .410, I believe he used Red Dot powder to do so. Want me to ask him for the recipe, or are you gonna go the new brass .410 route?

Pun never realised
I've just read through the first link and it seems its not as straight forward as I first thought. I never considered the case head chamfer and size
Further reading required as to wether this is worth the hassle and should I just stand the cost of Magtech shells

It's clever 'n' all but looks like an awful lot of work.

a friend of mine fire formed some .303 brass and did not have to alter to rim. Just see what fits.
