I'm trying to duplicate the winchester x-pert 180 pp load. I'm using winchester 760,, winchester large riflr primers and brass and winchester bulk pack pp bullets 180g. I heard that this will duplicate their load or close as my NEF 30 06 really likes them. Anyone tried this and can give me a headstart? The other thing is about coal. Depending on the reloading manual, it really varies from 3.340 to 2.750. I measured the winchester x-pert factory and they are way smaller! What gives! What I have done is start at 45g and load 3 shells each up to the maximum of 53g for the 760 powder. Then I decided that to duplicate the winchester factory loads that I would use their cartridge overall length for each one. I didn't have any compressed loads but I don't feel right about this as thier is so much difference between the length of the factory loads and the reloading manuals coal. Help!
