How do lead round balls (such as Gamo round balls ) perform in a rifled barrel? I figure they would perform better than in an unrifled barrel, but was wondering does anyone have any experience with these factors?

Of all the guns I've tried them through (all rifled)... I've been very disappointed. They are NOT consistent in any shape form or fashion.

The problem with round balls is two fold. First there is only one point of contact with the rifling. That means it is easy to strip the rifling off the ball. Second the rifling rate is MUCH too fast to stabilize a ball. Rifling rates on the order of 1:66 are what one sees in the black powder world, and yes BP round ball rifles are very accurate, even at velocities which are nearly double that of average air rifles. Get a barrel with a 1:66 inch twist and it will shoot balls just fine.

If memory serves I got some Hornady #3 round balls for one of my .25 DAQ's and shot 1.25 -3 inch groups at twenty five yards pretty wide spread for the most part. But great for whacking pop cans with my pistols at closer ranges.
