Just purchased nice Slingsby's of Boston England 16 ga SXS. Gun has 2.5 in chambers and is proofed at 3 tons and barrels measure 662. Shooting RST lite loads but I reload for skeet and clays. Can reload several loads ranging from 6200 psi to 8400 psi.
What would be max psi should shoot. These reloads range in shot weight from 3/4 to 7/8 to 1 oz.
Thanks to all
