Topped the rossi with a inexpensive simmons prosport 1.5-5+32 scope.After expermenting with different powders an bullett combos the rossi finally setteled down on 90grains pyrodex select an 300 gr 45 caliber bullets.........best grouping was .125 @ 100 yds.At 50 yds the holes were touching .Very warm here yesterday around 80 degrees...........let the barrel cool down 10 minutes between shots.swabbed the barrel every 3 shots.Not to bad shooting factory sabots......may need to try some other sabot an see if i can get that group to tighten up alittle.The breech plug in the gun looks very cheaply made .......does anyone make a better breech plug that will fit the rossi?
