    If you were to shoot a pattern on paper, 60/40 suggests that 60% of the pellets are above the point of aim (POI) while 40% are below the POI. 70/30 suggests a pattern that would have 70% above and 30% below. If you are hitting targets on the bottom, your gun is a little low for your methods - hitting the top means the gun shoots just a bit high. No one can give your percentages from the info you provided.....breakemall....Bob Dodd

    Bob- Point of impact (POI) or point of aim (POA)? Remember I am the poster who yesterday got the words two and tow mixed up in a post.

    There's no need to find out the percentage once you know where it shoots, in inches high/low relative to the point of aim.

    (in a whisper - this is just for you, mpipster, so others aren't offended.) When someone tells you at the club that his or her gun shoots six inches high at 40 yards, he or she probably knows. When it's said as "80/20" it's almost certainly worse than a guess, being not only never tested, but also so heavily influence by what the shooter wants that it's more a prayer than a fact.

    (whisper to chipking only) I'm sure many can make that conversion. But I'm also sure few have ever done it to see if they are right. Or have decided which definition of percent they are using (area or pellets) or have much understanding the effect of choke and distance, all of which are covered by the above link.

    My question remains: Once you know where, in inches, it shoots, why make the conversion to percent? What does it add besides uncertainly?
