Need some help with load data for 7x57R

[Ehgbyf]

This might be the wrong place for this but I am looking for some load data for 7x57R. I have acquired a few cool German drilling's and combo guns.

I am looking for a load that uses a powder that is readily available locally or I may have. I would think there is something that would work that I use for a 243, 2506, 308, 270, etc.

Any help is appreciated.

You should be able to use the lightest end of 7x57 data but if you want to cut out guesswork, VV has load data for N140 which is right around Varget for burn speed. Varget is ubiquitous in the loadings you mention so I also suspect you'd be able to work up a Varget/RL-15/AA2520/IMR-4064/BL-C(2) load pretty easily.

The rimmed version of 7x57 was made to operate at lower pressure for crack barrel guns. IMRpowder.com has load data from ~35,000CUP to 49,000CUP but the 7x57R is supposed to max out at 41000 cup. So, if you stick to the data on the minimum side you should be fine.
