Thanks guys. We just wanted to see if there was anything like these holders available off-the-shelf before talking to our local metal bashers. Seems like there isn't.
Cheers

I realise your old ones may be wider, but you could join these together (or just use them singly): https://www.pellpax.co.uk/airguns/ac...7-x-17cm/20448
Easy enough to modify a little once the bare shell is there if you want to. It is 3mm thick steel and, as has been said, this could deteriorate over time. But you could put a strike plate in (as per angrybears comment) made of any sufficiently dense material (plywood, steel, etc). Not sure what a fabricator would charge to knock up however many you need, but when custom work is required the cost usually reflects that.
We made our boxes out of ply and chipboard and lined the inside with steel sheet. 3mm was hammered by the pellets into a hollow shape and the corners lifted. Now we use a 5mm plate fixed to a thick timber substrate but spaced off the timber by a few mm using rubber grommets.
Initially we made the mistake of angling the striker plate at 45 degrees, thinking the pellet would bounce downwards. But because the pellets distort they don't behave that way, and the spent pellets tended to slide down the plate and smash holes in the base of the box at the back. We found that an angle of 70 to 80 degrees works much better.

My back garden target holder is angled at 45 degrees (2mm sheet, backed by 25mm ply) - yes, the pellets tend to strike down, but cured the problem by sheathing the base as well (same system with 2mm sheet + 25mm ply), have also added a length of steel lintel along the back as a 'spent pellet collecting trough' not had any deformation on the sheet steel, and I use up to 'full' power rifles on it at 10 yards & upwards, though probably not as much as a club or range would.
