Glad to hear it, iwantadouble. That .303 double's accuracy mirrors my own experiences with 'good' Brit SxSs and express sights.

That Rigby may have been re-regulated for the Mk7 cartridge, as most were originally regulated with Mk6 or earlier ammo with the 215-grainer at ~2000fps. I knew of one here in Oz which ol'mate Vic re-regulated many years ago, it was a fully-engraved sidelock with the Bissell third bite, marvellous! Not sure what happened to it, probably went to the US during the dark days of our 49-cent currency exchange rate.
