    I know this is basic physics, but in general is there any significant drop in inches between 1145 & 1200 fps @ the following yardages:

    1)16 yds
    2)20 yds

    3)24 yds

    4)27 yds

    Looks like the answer is a resounding "NO."

    And 7.5 @ 1240 FPS muzzle speeds up after 50 yards! That's how those guys beat me in the 'killer'.

    So, according to this chart above, you would not have to change anything on your gun to hit the targets. A drop of 4" at 40 yds. would still be hitting the center core of the pattern. Even at 50 yds. You move your comb up an 1/8" and you move your pattern up 15" at 40 yds. Seems to me you would have to adjust for the sight picture change, and not the POI. I see very few people if any, changing there combs in shoots were you shoot from the 16 yd. trap and move to the next trap and shoot the 25 yd. marker.

    Stl, moving your comb up by 1/8" raises your POI by about 4" at 40 yards, not 15.

    Drop and poi is not what gets you when you move further back, it's our perception of the "sight picture" that causes problems. IMHO.

    Does anyone know at what distance does the average shooter actually break a singles target.

    The faster the muzzle velocity the faster it slows down. HMB

    Phil, I break singles targets between 25 and 30 yards. Most of the other ATA shooters I shoot with are a touch faster, some a lot faster. Ordinary non-ATA practice shooters are a lot slower. 30 to 35 is about average for them, but about 10% shoot when the target is at it's apex, or on the way down.

    I really think speed is more a question of aiming or not. People who aim take a lot longer.
