Of course it all depends on the quality of the relica you buy, and even more so on the rifling. I have an old Italian made Zouave repro, (Only brand on it, says, "Sears Roebuck & Co on the brass trigger guard) With round balls and wiping between shots, I can consistently hit a 9 inch circle at 125 yds. I understand that Parker Hale makes an Enfield with the same style rifling as the originals, ie deeper at the breech than at the muzzle. The early trials of the original rifles in the 1850's showed quite good accuracy out to 500 yds. But they soon found that successive shots became increasingly and then nearly impossible to seat the minnie balls. In the heat of battle, this is less than desirable. So instead of tinkering with the rifling, the Brits tinkered with the types of bullets and cartridges. They tried wrapped with a tail, combustible etc., The only thing consistent about the constant tinkering, was that they kept shrinking the diameter of the minnie ball and each time found that accuracy suffered as a result. There were nearly 20 official changes in the cartridges and bullets for the muzzleloading Enfield by the Brits between 1853 and 1880. I've visited Ft Shenandoah where the spring and fall skirmishes are held, and those guys can consistently hit 6 inch targets hanging at 100 yds, and they are shooting offhand. Obviously in standard hunting situations, one would rarely if ever have to load more than three shots without swabbing the bore. And with the new substitute cleaner burning powders the risk of problems goes down even more
