I have one of these rolling blocks that is in excellent condition that I would like to shoot. I have read so many conflicting stories on the strength of this gun. Can anyone recommend some load data for jacketed and cast loads that are safe. I have read the (Norma) loads are not safe. I know someone out there has already figured this out and I am not very good at load development when there is no printed data available. I am new to this forum and find it a blessing to the single shot shooter.

Thanks,
JMH
