Hi all, New to reloading and have been doing a lot of research and overwhelmed where to start? I have a Ruger M77 7mm rem mag made in 1972. pillared barrel, glass bedded, trigger job. Bushnell elite tactical 6-24x50 set up. 10+ twists. Previous owner did hand load but load info not available. Was pretty good from what I remember, just never asked for them?? It was 10+ years ago anyway so... I have had a hard time getting factory loads to shoot well but never really performed any tests to identify what it likes. I was thinking of shooting 168 Berger classic hunters and 215 standard primers in whatever brass and not sure on the type and gr. powder. I don't want to just start trying 100 different powders and grains and ..... such and not sure there is a better start up scenario? Anyone with this gun have any load data and process to get me going?
