I did state the powders, but not in the first post. In post #6 I said I was looking at using Bullseye, AA#2 or Red Dot.
That makes sense. After I thought about it I realized if the bullets are the same weight, they take up the same volume. So maybe the HB is longer than the DE?If you seat them the same depth I think HB and solid base wadcutters take up the same volume.

The limit on pressure for a HBWC is there so you don’t blow the head off and stick the body in the barrel or cylinder gap. DEWCs don’t have that problem so they can take a lot more pressure. The thing is, these days most DEWCs are bevel base and cast from hard alloys so they don’t obturate at the base to seal the bore. That kind of bullet leaks gas pretty easily so if it’s not oversized it’s not sealed. You can run the charge up pretty high and not get as efficient a result as less charge in a softer HBWC where the skirt expands to seal the bore.That makes sense.

That is really good info, and an excellent example of why you can't sub data from one bullet to another just because they're the same weight.The limit on pressure for a HBWC is there so you don’t blow the head off and stick the body in the barrel or cylinder gap.

I have used standard SPP with faster burning powders frequently over the years, i.e. Accurate No. 5, Unique, W-231, Titegroup, Bullseye, and Universal. No problems in assorted revolvers.Can you do the opposite? Could you load say 6 gr of AA#2 with a SPP in a 357 case? I know with slower ball powders you need the msg primer, but wondering about this.
