    Got a Big Beeza

    Nice and clear so not the problem, gap between 50 & 55 about 5mm with a 'click' difference of 21.
    How do you re-parallax to give a bigger gap ? Bigger wheel is one way to go, but say I just want to know for future reference.

    If it comes down to ten yds,leave it alone,you loosen the front ring and wined the front lens .

    If it snaps in nice and consistent, leave it alone. 5mm is plenty to range to the yard.
    Maybe have a magnifier if you're struggling to see it.

    5mm is plenty could halve that and tie down to 1 1/4 yard.
    Only ever come across two old BSA well over a decade ago where the gaps became larger, all others didn't work or reduced gap ranges and performed crap. Leave alone.

    21 clicks at 1/8" is excessive looking half that, I would check if its holding zero having seen dozens that wont. Initial signs will seemingly be non progressive clicks ie big jumps in clicks for a couple of yards.

    I have had one of these from new 14 years ago and it works great I have tried 2 big Nicko's and have gone back to the beeza and if it aint broke don't mend it is my opinion. :)
    Leave well alone.

    Big Bee as do have quite small gaps 50-55 so people usually use a tear drop style side wheel.



    See you on Sunday???

    Jon is spot on. You should only have about 12 or 13 clicks between 50 and 55, even with lowish scope. Don't worry about the apparently small gap, if you get used to it it will be fine. I have a Big Bsa on my HW77 and I'd say the 50-55 gap might be even smaller than 5mm but the range finding is faultless.
