I was just wondering if anyone has reloaded and used the Tubbs Final finish bullets in there handgun. I have read that it may improve your group to about half the size and makes the cleaning a lot easier once you get the burs out of the barrel.

I used them in my AR15 and I think its a good product. A friend of mine believes that it will shorten the life of the barrel if I use it. I don't believe it will hurt the gun, but just make it better.

Anyone use them and actually see better groups after using the bullets in there handgun?
