Not too bad!!
Check this target out!
Open iron sites (no scope) from 80 yards with my Marlin 336. 170gr. 30-30 Winchester Silvertips
Not too shabby. The first shot was low and I adjusted the sites accordingly. Its a pretty gosh darn nice 3 shot group, if I do say so myself. Too bad the deer have to wait another 10 months before I can really test it out.
Shot it at the Shinbone Ridge public range in LaFayette, GA.
Its a good spot to spend the afternoon (or several of them!)
