Tom,
Am also taking a Rigby engraved Webley 1902 patent falling block that I had rebarrelled in hand-detachable .375 and .300 flanged magnum barrels back in 1986. Hope to do a hartebeeste with the Coggie and a duiker with the .375 and something that requires a scope (no iron sights on the .300 barrel) like a klipspringer or damara dik dik.
Regards, Tim
