I ordered 50/70 bullets from Old West Scroungers. They say smokeless. The company( OWS) says that the rounds are LESS pressure then Blackpowder???? Another company I contacted claims Blackpowder is Less pressure????????? The gun looks very good. But I dont want to shoot the wrong bullets in it and damage it. What do you guys and gals shoot out of your springfield 50/70 trapdoors? And what company do you get ammo from.The ones I have say 50/70 goverment 450 grain lead bullet j and j products xl-20b starline brass
