John it's fired full jacket before. The fired bullet that came from that bull is in the case and it is a jacketed Woodleigh. 440 grain Woodleighs is what I was told he shot in it. I'm never going to shoot buff so I will play it safe and use cast only. Pity as I have 3 or 4 boxes of Woodleighs sitting on the shelf with nothing to use them for.
