150 grn gaschecked home cast with 16grns Unique, gives me around 1700 fps and I have hit the target at 200 yards with them, although mostly they have been used for gallery use at much closer range, still giving .223 ME levels though !
(the gas checks are seating below the case neck with this bullet, although I have some K31 cast to try which should seat higher )

I’ve been loading 8.5gr unique , shooting at 25 ,I’d say 10gr would be quite a powerful load, I download 7.62x54r with 10gr 150gn heads

just had a look further back in my notes, I did load some with 11.5grns unique for 1400 fps, settled on the 16grn load as really no cost implication and I intend to try it more at 100/200 when we can go to the range again, very soft shooting load with almost no recoil, I have a 200 grn mould which I was planning to try in my 1889 but with the current situation I suspect my FEO would be loath to let me add it to my FAC so that will wait, may try them in the K31 but they will protrude a ways into the case .
