Has anyone figured out or found a percentage of charge reduction when subbing SRs for SPs? I've got 6k of WSPs and about that many 9x19 bullets to load, but I also have about 3k Berry's plated RNs to load for .38 Special. My PX4s and CZ-75s will work with the Fed 205s I have and I think my P99Cs will too, but I'm pretty sure my revolvers won't.
Powder will be BE-86.
