Firing the Boys Anti Tank rifle

[browningautorifle]

I had often thought of making a big calibre rifle from an old M8C spotting rifle but ammo wasn't available nor were reloading facilities so the project went sideways

Dies have been available for ages for that and for practically everything else. I know we looked at it back in the early '90s and you could get them from RCBS. I'd use .50 ammo and reduce it...
