I shot my new Armi sport Spencer today with my reloads. I pour a 350-360 gr. bullet from Accurate molds( it's made for the 56-50 cartridge) . I read where 12 gr's of Trail boss was a good load. my cases wouldnt take but 10 1/2 gr;s of TB. with out compressing the powder but I"ve heard you don't want to compress TB. but that load was very accurate I did have a couple of one holders at 25 yards(I don't know if I can see the target at 50 yards yet.(new glasses, don't you know), the rifle worked flawless, if you worked the action with great vigor. it fed and ejected sideways or straight up or pointed up. The sights seem to be about an inch to the right at 25 yards. that's pretty good for the first shot's out of the box. The trigger waan't too bad. this was my first shoot with it and I need some more time with the rifle. but i'm in love with it. I tihink it works better than the orginals(and yes, a friend has a 153 year old spencer we're shooting also.
