Rifled 870, full bore Mihec round balls.
Thank you,Santa!
This is my first ever rifled shotgun group. 50 meters, kneeled position. Full bore (.732") 555 grain round balls, I forgot to pay attention to sprue position.
Gotta say,positive first impressions. I fired one ball @ 25 m, then moved to 50 for this group.

This is only 1200 fps ,I'm proceeding slowly. Gun is old, well broken in, chipped stock laquer finish but very good metal parts...? Also came with a clean 26" railed hunting barrel. Rifled barrel is "new", there was quite a lot of lead and then rust under it... spent all night on it yesterday, I mailed the shop.

My first hull did not extract,I got worried , the rest was no problems.
Anyway, the lead/rust did not completely ruin the rifled barrel. It's just that I now KNOW the barrel was not new, I wanted a new rifled barrel to avoid this exact thing. Idiots shoot bare lead and shot and nails with these and never clean. Basic slug understanding is scarce around here where I live.
Maybe I'll get my head cleared about this. Paper looks promising, my record 50 m slug group ever I think.
