Hi Roy,

I'm circling back on this project to say I've spent a couple of hours resizing RWS brass to fit my double's tight chambers, using scotch tape, as discussed above. Once I had that done, I neck sized using 357 Mag dies and then belled the mouth slightly to accept 200grn Hornady jacketed soft points (as you suggested.) If the weather holds off tomorrow morning, I'll sneak up to the range and try the 10 rounds I loaded using IMR 4895. Fingers crossed.

A 38-55 trim die was suggested as a possible way to compress the case body without messing with tape. I bought a LEE trim die for this reason, but couldn't measure any compression of the case dimensions when using it. So a lot of time practicing grade school craft skills with tape.

Will let you know how it goes.

Chris
