True Blue with Lead?

[steve4102]

Anyone loading True Blue in the 40 with lead bullets?

I have only two sources of data, the Lyman Cast Handbook #4 and Ramshot's web site. My bullets are home cast 180gr TC and a second home cast bullet same mold converted to HP dropping at 170gr.

Ramshot lists a Max of 5.7gr True Blue for the 180gr Lead TC while Lyman list a Start charge of 6.3gr with a Max of 7.0gr.

I'm not sure where to even start? Anyone shooting lead in the 40 with TB that could shed some light.

Thanks
Steve.

The RULE is to always start with the lowest starting load you can find.
My only data (probably from RamShot) is for 180gn L-TC: 5.1gn True Blue start, 5.7gn True Blue Max, min COL 1.120".
My experience with True Blue is that it is very good from light loads to max loads.
I have shot 177gn L-SWCs from 5.2gn to 6.7gn (which did not seem to be a max load) of True Blue and Rem 1 1/2 primers, with best accuracy around 6.0-6.4gn.
