Very nice rifle looked for an officers model but I've never even seen one except pics. I did buy a plain jane model blued and wood it has been just excellent accurate and great to carry .
Found a 44cal. Hornady 300 gr XTP, two 50 grain Pyrodex pellets and a RWS no.1075 cap (no.11 caps fall off) to be the load of choice for me not much kick and never had a ftf that wasn't my fault once I started using the RWS caps.
My dad liked mine so much he had me find one for him same basic 77/50 as mine he uses the same load except for 240gr XTP's just to be different his is just as accurate as mine they don't seem to be a bullet fussy gun.
Have been using my 77/50 for about 12 years give or take, dad 3 or 4 .
Was lucky enough a couple years ago to pick up another one a little different stainless with a grey laminate stock have only shot it one day a few times as mister graceful here snapped the ramrod. Now that I'm not working out of province I plan on getting it all ready for next hunting season .
The only flaw thats not really a pain but just time consuming is cleaning them and I believe the cause of there demise .
Once again nice find enjoy and if the cleaning is too much for you keep me in mind.
Later
