    crossover

    Hi, How much crossover is acceptable? With my rifle zero'd at 35 yards I get about 2 cm at 7 yards. I've already bought some special mounts to fit the 13mm dovetails which has helped, I just cant seem to get rid of that last bit.

    For target shooting no. That's a mile out.
    It will also put you out at 45 yards as well.
    Check it is xover first though by checking indoors at 15 and 30 yards, or on a windless day.

    Your xover could be down to you miszeroing at 35 yards - miscalculating wind will put you out at 8 yards. Equally it could be parallax error at 8 yards

    The parallax is fixed at 27 and I last zero'd on a windless day. I guess it could be close range parallax error, the comb height is definatly too low, I'll check it out. Thanks

    To have 2cm horizontal discrepency at 7 yds when zeroed at 35yds, your pellet path would have to be the shape of a banana (West Indies type, not EU standard straight ones).
    Parallax is likely. The other thing it could be --- Are you holding the rifle perfectly vertical ? If you're tilting it so that the scope is 2 or 3 cms from the barrel vertical this will give you a similar error at close range.

    I thought cant was not so noticeable at close range. You can tell if its crossover, not parallax, 'cos if its shooting right at 7 yards, it will be shooting left at ranges past your zero. When I get paid, I'm getting some BSquare adjustable mounts.
