I have also owned 3 RUM's and love the power and fun I had with them. But I did burn up the barrel in one and had heat cracks in a custom one I had built after 500 rounds. If it wasn't for the harshness on barrels, I would have another one. I instead have a win mag. I miss the RUM. It was fun for long range shooting, but 300winmag will be fun too.
