What I want to know is...is it possible to load 38spl cases to 357mag loads. Having checked the ADi website for 357mag cases I would need 6.3gns of AP70 to meet power factor for major. The 38spl cases still have loads of room in them to accommodate 6.3gns. Its less than a grain higher than what I am shooting now and I am seeing no adverse effects on the cases, primers etc at present. It would be amazing to be able to up my powder charge in 38spl to major power factor. Any thoughts........
It's probably possible, but please promise to let me know when you are going to the range to test them. I will be sure to stay home that day. :-)
