I started reloading back in Denver in 1962. We would just fill up an '06 case with 4831, jam a 180gr Nosler and go Elk hunting. I got my first Chronograph 5 years ago and the end result is wonderful. I am safer, more accurate.....way more accurate, faster and consistent. Second to the Chrony is the OAL gauge. With these tools you can absolutely get out of your rifle 100% of it's capabilities. IMHO if you don't use these tools, you might as well shoot factory junk. Good luck and regards, Rick.
