I didn’t know you are short sighted as well, maybe you misread your Gempro and put another grain of powder in. Don’t worry Neil, Specsavers will be doing their 2 for 1 special again quite soon. I’m sure a pair of bifocals will work a treat. Kill two birds with one stone - you’ll stop missing the target and get more consistent powder charges. Winner winner, 3 legged deer for dinner 😉😂
