Actually CZ mentions one thing that I've seen and heard on, which is, hornady apparently says their new CX/Gmx all copper bullets are made of an alloy that is softer than ones like barnes, so powder charges don't have to be reduced with these hornady pills. Now I'm not certain of this but just mention it...
If that be the case I might (if I had hammers, which I don't) use the 90 gmx/cx hornady data, starting low but expecting hammer MV to be slightly higher than the cx, load for load, since it is 3 gr lighter. A 3 gr weight delta IMO wouldn't rule out using that data, as some bullets show loads for pills with a 5 gr wt. delta, eg: the 95 sst and 100's of hornady in the 6Arc.
All this is theory. I personally don't plan to use any of the lead free b/c I'm concerned they might be just a tad light at 6Arc velocities, just my opinion however.
Interesting the 3000 MV fps for CZ.
