The no confidence is due to some cartridges not breaking sound barrier and some of them at (guess) .45 colt +P loads. If the 45 colt +P is all the Blue Dot powder that will fit in the case, then I could use them in my 25, just not a steady diet.

Could shoot all of them through the Taurus, but it's a lot more fun shooting an N Frame.

Will pull a bullet with the pliers method to check case volume. I don't have any experience with Blue dot volume.
