Just got to shoot my new No.1 Tropical in .416 Rigby. I have seen many comments regarding the safety standing proud, and various fixes, including the after market safety slide. My question goes to adjustments in the ejector. Is there some recommended setting? I have screwed the allen screw in to where there's about 1/8" thread showing. It will eject a heavier dummy round nicely, a shell, only, clears the action but no 'umphh' behind it. Secondly, my son tells me he read it's perfectly o.k. to dry fire a no.1......any opinions? Bill
