I bought 150 .575 Round Balls and, having both rifled and smoothbore .58 weapons , I bought them to try "roughed up" and lubed in my smoothbore.

However, this might also work for the rifles?

I'm sure someone has tried this .
 
I tried roughing up balls with a farrier's rasp. I went back to smooth balls. One thing I didn't like was that the dimples increased corrosion on the balls and well as dirt collection.
 
I'm sure the .575 diameter ball will work rather nicely in a smooth bore but the idea of using a "roughed up" bare ball in a rifle is a poor one.
Without a patch little if any of the roughed up ball will be able to engage the rifling grooves so it will cause severe leading in the barrel.

A .575 diameter ball is just about the right size to patch and load in a .58 caliber barrel. Just a bit snugger than the .570 diameter balls usually shot from a .58.
 
I'll just use them in my smoothbore
May as well try them in a rifled barrel and eliminate the speculation. You will know first hand one way or the other. I have used knurled or ‘roughed up’ conicals in a different (not discussed here) application with success. I have doubts about a ‘roughed up’ roundball working in a rifle, especially one with deep roundball rifling, but haven’t tried it myself. Go for it and report back.
