After corrspondence with both Alliant Powder and Hornady, here is the latest info as far as I know.
Hornady has come out with reload data for their FTX bullets, used in the Leverevolution line. The info is available here:
Evidently, you should not use load data for standard bullets when formulating these loads. The old adage of "starting with loads for the next lightest bullet weight" is out the window with these bullets. It is very important to use this data to stay within max pressure. Here is and example of why:
The Hornady bullet is 160 gr weight.
Alliant data for RL-15 powder and 150 gr jacketed bullet gives a max load of 34 gr., so a 10% reduced starting load would be 30.6 gr.
My Lee manual lists 32.8 gr. as starting load and 36 gr. as never exceed.
If one were to err on the conservative side and use the Lee 150 gr. bullet starting load of 32.8 gr., you would be a full 3 grains of powder over the max charge published by Hornady, which is 29.8.
Even using the more conservative Alliant starting load of 30.6, you will be exceeding the max load.
I believe the reason for this is that the Hornady bullet's crimp groove is much farther to the front and the rear portion of the bullet is longer, to keep weight up and OAL down. So it seats much deeper in the case. Thus increasing the bearing surface, compressing the powder, and thereby increasing pressure.
The good news is that Hornady tested the loads in a 20" barrel (at least for the 30-30), giving us some velocity numbers we can use in standard length barrels.
