    What are the disadvantages or advantages of having 1/2 MOA clicks on a scope which will only be used for HFT?

    TIA

    I can't think of any advantages
    1/2 MOA at 45 yards is about 6mm so it depends how accurate you want your zero to be really

    Thanks Brian.

    if at 45yds poi is 6mm from crosshair, will the poi at say 15yds, still be 6mm from crosshair, assuming correct elevation is given?

    Regards

    Hi Dave

    It'll be :-
    2mm at 15 yards
    4mm at 30 yards
    6mm at 45 yards

    If the clicks are 1/2 MOA on both turrets you could be out by up to 6mm at 45 yards on both windage and elevation. So at worst, just over a pellet width out.

    Not a massive problem, but certainly not an advantage.

    What's the scope?

    Thanks again Brian.

    It's a leupold Mark 2 4-12x40, I ordered it yesterday before I found out it had 1/2 clicks.

    Cheers

    Put it on adjustable mounts and your problem is solved.

    Adjustable mounts in my opinion will test the patience of the friggin' Pope!

    Some do, some aren't quite as much of a PITA!;):D

    I've only used the b-square adjustables and they're a real pita to set up. I wouldn't fancy trying to set one up to 1/2 MOA. With alot of swearing you could possibly do it on windage, but you'd have to be lucky on the elevation.

    Dave are you sure it's 1/2 MOA? That sounds odd for a normal scope - especially a Leup!

    With the scope you are stuck with the 1/2 MOA.

    At least with adjustable mounts you can do something about it. Don't use adjustable mounts and struggle with the scope.
    I know which route I'd take :D

    Personally I'd wait until you've tried the scope on ordinary mounts first - the T2 turret might only be Marked up for 1/2 MOA but may allow adjustment to 1/4 MOA.

    If it really is 1/2 MOA and you go down the adjustable mount route - Don't go for b-squares. Its not possible to adjust elevation on the b-squares to 1/4 MOA accuracy. Getting the windage right would also be more luck than judgement too.

    I can't comment on the Sportsmatch adjustables as I've never used them.

    Try sending an email to Leupold to confirm

    I have two sets of Sportsmatch adjustables that I bought for benchrest shooting.

    They are fantastic they do what they say on the tin and centre the scope optically beautifully.

    They are unbelievably easy to dial in and I do mean this.

    I don't use them anymore. For FT they may well, probably are perfect, for benchrest I'm not sure.

    For HFT no way they are far too as in extra high Sportsmatch low and a 25mm tube with 1/8th inch adjustments. It just makes sense.

    adjustable mounts are easy to set up if you think about what you are doing 1st.;)

    I've used various adjustable mounts since the mid 90's and now will only use a standard mount if the scope is close to optical centre when zeroed.

    B Squares are not brill to be honest, but sportsmatch are very good. The best adjustables are the old hilvers which sadly are no longer available, full steel construction and can be set up using feeler guages which takes out the "up a bit / down a bit" trial & error.

    Waiting to be shot down in flames, but if 1/2 MOA is 6mm at 45yds, surely the most the zero will be out is 3mm?

    will echo the comments about b-squares vs sportsmatch.

    the b-squares will only give you a certain elevation adjustment because they rely on the rotation of the shaft to do so, which can only fit in every 180 degrees... the 2 piece are easier to setup than the ones, because you can just lift the rear of the two piece off the dovetail, rotate 180, and replace.

    the sportsmatch use a grub screw, so with nipped up mounts you can simply just dial in the elevation, and then tighten the mount up and it's sorted... i've got the ones that only have elevation adjustment and I think they're my favourite mount to date.

    No flames - you're not wrong, I was :eek:

    Since 6mm is one click at 45 yards, the most it's going to be out by is 3mm at 45 yards and if you're lucky it could be less.

    Personally I'd still try it without adjustables first and take it from there - 3mm isn't a lot at 45 yards, you might be able to live with it.

    Thanks for all the replies, they have certainly put my mind at rest.

    Eagerly awaiting delivery now. :)

    The 1/2 MOA clicks wont be a problem. Simply means the point of impact wil move 5mm at 45yd instead of 2.5mm with 1/4MOA for each click. Once its zeroed its zeroed for HFT whatever the clicks.

    Forget the adjustable mounts, wont make a scrap of diference to the scop clicks. For HFT you should get the scope as low as possible and shouldnt need elevation adjustment. These are for FT boys who use them instead of scope packing. If you need them use Sportsmatch, B-square are a PITA and loose zero.

    my bsquares have held, even on a springer, but i agree that the sportsmatchs are easier to setup, by a long way :)
