I ordered and got some ETR7 powder and was wondering what the charges would be for each application.
The load data they list covers everything I load, but they are using FMJ bullets. And they say it loads like tightgroup, but I have never used tightgroup, so I have no comparsion to work with.
So, is there a rule of thumb for powder charges when going from FMJ to cast? Something like 10% less or 15% less or what. Not looking for max loads, just a good starting point.
Any help and advice would be appreciated.
Thanks. :???: :???: :???:
