I haven't worked with them much but I've heard good things about the Deep Curl. The older gold dots weren't as tough, the only problem I had was in my particular guns I had to download from the XTP. It seemed like the copper was softer but they would build pressure faster.

I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them. John Wayne-The Shootist
