warpig1976:

Thanks for your response. Being a new reloader, this is my very first batch, and the books all warn to heed the directions lest a gun explode in your hands. So I'm keyed to being ultra cautious.

If the reality is that cartridges will be somewhat different, and still safe to shoot I can proceed with my climb up the reloader learning curve. Still this batch will only be 10 rounds in size. I'm feeling my way slowly.

Kind regards. Ray
