Pretty good in fact very good but how many rounds did you fire and how many counted for the grouping , and it must have been a very still day , and what weapon were you using. Not disbelieving you pal just interested, but still a good group.
I could get a 1 inch group at 300 mtrs 5 rounds with a 7.62 SLR, on a very good day by just using the iron sites normally it was a 2 or 3 inch
