Reeder Custom Guns - .454 Casull Pressure

Loaded to the max I believe the .454 reaches pressures of 60-65,000 CUP, that can be brutal for both the gun and the shooter. Does anyone know the pressure of the Hornady XTP 240 and 300 gr factory loads? Also, how is pressure measured?

Actually .. books have been written. It's no "easy answer" thing.

Here's a few starting areas:

Taylor or one or two other good friends that are writers and he had just done an article on the 454 Casull and told me some of the ammo tested ran 70,000 CUP which is extremely hot and rough on everything, hands, elbows, knees, lower back and small toes.Just another reason for me to stay away from the 454.

.454 Casull Pressure

Seems like a question for Hornady Techs....

If you are interested, you need to read articles about it.

several years ago I talked to either John Taffin or Jim
