Help zeroing my Sten

[browningautorifle]

Going with what our CAMT states, the group would be X2 for the acceptable size. IE, 3 1/2" X 2 is 7 inch group...or at 100 yds would be 3 1/2 X 4 =14" group...that's a lot.

Now, I don't know what the EMR states or the UK AMT for the Sten Machine Carbine...
