Steve from Hammer told me that they have found the Nosler reloading data to work well for their Hammer bullets. Obviously, you need to use the data for a bullet of the same weight.

Apparently, the Hammer copper bullets do not generate any more pressure than the standard cup & core Nosler bullets. I have followed his advice and find that when using the Nosler data for Hammer bullets you get (essentially) the same velocity. I have not experienced any pressure issues when using the data this way.

FWIW - the 181 Hammer bullets shoot exceptionally well with IMR7977 in my 30 Nosler.
