If you are changing the components in a recipe, you MUST work up the load.
You can not simply use a load at published/tested MAX for a different projectile and presume it is safe in your firearm
The is especially true if you are trading out a JHP/JSP/FMJ and switching to a total copper projectile.
MAX pressure will come at a lower powder charge with a total copper projectile in your recipe since the Total Copper Hollow points will aggressively resist deformation as the projectile travels down the bore
6-8 years ago we worked up new loads for the Total Copper Hollow points in 9MM, 357 Mag and 45 ACP
As has already been mentioned a Total Copper Hollow point will be longer than the JHP/JSP/FMJ projectile of the same weight. This may require deeper seating which will also alter the point at which this recipe reached MAX pressure
