Went a'shootin' my 91/30 today. It has my adjustable front sight and the ammo, I believe, was Romanian surplus. Whatever it was, it was steel cased, steel core, copper washed, and 148gns. The only headstamp was the year, "88".
The rifle does have a cork bedded barrel.
Possible to do better? I don't know with this ammo. I do not know if those fliers were me or the ammo.
I need to go find some more of this stuff, though, and try it at 100 yards.
