I tried it years ago with a couple of bullets, I think 220 gr and 250 gr Speer's. I found erratic speed and accuracy and it didn't burn cleanly. Probably not what you wanted to hear but I moved on quickly from it, other's may have found better results though. Have you tried it yet or just thinking about it?
I use to use it and during the powder shortages I started using rl15. I just picked up some BLC2. I never had accuracy problems. Since I havent loaded up up any ammo in 5 or 6 years with Blc2 I thought I would ask.
