Nice shot website says Nice shot reloads like lead with no special reloading data required. Then why is there special reloading data for Nice Shot. I'm confused

If you are asking this three times, you must be in a big hurry?

What the Nice Shot website says is "The result is a non-toxic shot that is as heavy as lead and almost as soft. It is made to be used as a lead replacement. Loading this shot does not require special wads, unlike other non-toxic options."

It means what it says, no special wads needed, and you can use standard lead reloading components like many already have, inclusive of the better hulls to reload with (compression-formed hulls) that have low case volume and are very limited with steel.

The website goes on to say that "Nice Shot" has a slightly higher chamber
pressure than an equal lead load.

Tests by Hodgon and others show a slight increase (1500 PSI MAX) of chamber Maximum Average Pressure.

SAAMI MAP pressures are:

Pick a book load that is 9500 PSI or less, and you are good to go. However, specific loads have been worked up by Precision Reloading as well:

"Precision Reloading's Technical Support will help you with your
loading questions and data. They can be contacted at 605-996-9984
to speak with a technician 8:00 AM – 5:00 PM CST."

The majority of the loading data is fine but if you like to load your rounds HOT, is why a warning had to be posted.
