M sure this has been asked and/or debated plenty of times between friends on and off of forums. But I'm kind of curious, do you guys find a difference between a copper plated .22 and an unplated one? I'm not referring to the amount of cleaning needed to be done since I've heard that the lead ones tend to leave a waxy build up as well as lead residue in the higher velocity rounds. What I'm asking is to do with the accuracy and feeding of them. I jut bought a box of winchesters Expert High Velocity and didn't realize that their not plated. Also wondering how well lead slugs tend to cycle in a semi-auto firearm.
