You're right IMO, AZAK, and I use standard pressure .45s for the most part also. What I was comparing was a 185 grain +P .45 as loaded by Remington compared to a .357 loaded by any of the Big 3. Getting into a load by an ammo "boutique" like Buffalo Bore is another thing altogether. Apples and oranges.
Use it up. Wear it out. Make it do, or do without.
