    What causes "Droppers"

    I have a factory rifle that shoots pretty decent, averages in the 3's but 2 or 3 in 25 shots it will drop a low flier, like 3/4 to 1" low. I have heard them called "droppers" The rifle is bedded, firing pin profiled, have shot 3 different lots of Center X, all do the same, one group will be going great and all of a sudden one will drop low, this is in a no wind situation to. Your thoughts appreciated

    I hate it when there is no wind.

    I agree with that no wind statement.
    Mirage may be doing you in.

    Profiling a factory pin is still largely a factory based fire control system.
    Spring.....friction somewhere......trigger......drag on striker......any or all are more than likely causes.
    Still a possibility is priming especially with improperly stored and/or badly handled ammo, even top shelf stuff.
    Condition is a possibility, mostly if you have a head or tail wind.
    I assume you shoot over flags ? Should have a minimum of 4.

    Then don't shoulder a shot! Try never to repeat mistakes.

    Sometimes someone asks the question I've been thinking. My backyard range snakes between trees and seems to cause some peculiar wind effects. Shooting a 2500X with Muller barrel or a Trident with Benchmark 3 groove, I get those shots that just fall out the bottom, almost always when the flags are hanging dead. Both rifles seem to shoot quite flat if the wind is steady. I plan to watch myself closely for shoulder position next time I practice. It had occurred to me that I may have been touching the stock inconsistently with my shoulder.

    Have you fired any of this over a chronograph to rule out velocity variations?

    Do you have "Droppers" with all brands of ammo?
