I have a 6 inch ruger i want to reload with, i have, to start, Bullseye, CCI 550 primers, Hornady XP/JHP and Winchester SJHP Notched, im using these in 158gr. I want to find out whats a good recomendation as far as starting medium and working my way up, im more familiar with reloading rifles. So is 4.5 Grains, or 5 good to start. Im not shooting on a daily basis, and am not shooting under 25 yards, so no rapid fire. I carry for hunting too, so i dont want various charges. Wanna keep it simple, a good load for hunting and shooting. Without blowing it up.......And can someone explain the CRIMPING Process, and what to do, Im using an RCBS RC, so single stage stuff.
