Hi again Joshua, my Siamese Mauser is currently chambered in 7.62x54R.Cases and loaded ammo are easy to get,I have been using some Russian made steel case stuff with 250gr soft nose and it hits like a ton of bricks, but feels like a shotgun to shoot.
All I did was fit an old 303 SMLE barrel to it and cut a new chamber....its a roughy but its hell on pigs...fitted an old Pecar 4x post and crosshair scope to it and made it even better.

......its about to get a new G&H style stock, a new barrel in 405 Grenadier and a general tart up for the old girl.
