I only use 230gn Barry's Copper Plated FMJ bullets for my reloads.
4.6gn - Tite-Group
5.5gn - W231
5.0gn - Bullseye

The most accurate in my guns is the 4.6gn of Tite-Group. The 5.5gn of W231 is right there as well. I have plenty of Tite-Group and Bullseye, but very little W231 and I cannot find any!
