I shoot mine in standard configuration (With pecar scope) and RAHS 3 rings
100 yd zero.
I use 144 grain Radway (difficult to find now).
You will get 600 yds of elevation from the scope and i was regularly getting
high 40 scores, with the iron sights you will get to 1000 but i think the 144gr
bullet is too unstable at that range, resulting in larger groups.
In short it's as good as any other 1970's -1980's target rifle.
Alan de Enfield posted some grouping pictures last year of his enfield
looked pretty tight.
