    I have just bought a S&B scope with the Bryant Reticule anyone know anything about it? I bought it NIB but the instructions were missing. Went back to the store but all they got were the instructions in German.

    Hello,
    I have a S&B PmI with this reticule.
    As the link shows most parts of the reticule are for 50cm sized targets @ 100Mtrs IE the main circle and the uprights above and below.
    The lower lines are to fit in the same 50cm target @
    200M 300M 400M 500M
    These would be very handy to measure a human target with 1mtr being the average measurement between crotch and top of head
    The other lines are all sizes referenced to 100Mtrs ,17cm,33cm



    If yours is the same as mine it could have 0.7cm @ 100Mtr clicks by the way (took me ages to find that out as its not marked on the turret).

    Jeza

    Many thanks for that I am amazed it has only 0.7cm @100mtrs the other thing I found out was it only has about 44 clicks total elevation is yours the same? how have you over come this I am toying with getting a new rail 10 MOA slanted to try and bring it up a little. Any advice would be greatly appreciated.

    Also are you Suffolk UK or USA?

    Eh - on my PC it came out in English!

    TRY www.schmidt-bender.de

    Click ENGLISCH - THEN PRODUCTS - THEN POLICE MARKSMAN SCOPES - THEN on the bryant reticle!

    Im in Suffolk UK!
    How about you?
    Mine has got 40 clks available.
    Have you got a stop in the turret that only allows one full turn?
    I have already done some research on this and found out that it is possible to get a turret without the single turn stop in it. This would allow you to take full advantage of the 30mm tube.
    You would not have an indication of how many full turns you put on though.

    If you already have a multi turn turret and have hit the stop you then need the canted base to set the reticule off centre at your zero point
    I have actually got a 20moa base on order this seems to be standard on here.

    Looks interesting for ranging-- could use the x-hair-lower post @ 9", and punch it into the "modified mil-relation formula" for more ranging flexibility for many different tgt. sizes--

    say, a cow elk (20" back-brisket) tgt. size in inches x 100 yds./9"/elk brackets 1.0 ranging unit== 220 yds.
    20" tgt. brackets .9 RU== 250
    .8 = 275
    .7 = 320
    etc.

    6" could be handy too, as well as the ranging lines themselves-- substituted into the above equation using the 200 yd. subtension as a main ranger with the others as a % of that subtension.

    I'm in Sth Wales will be up your neck of the woods in about a month.

    Not sure about the turret stop but yes if I need more clicks I have to undo the cap and turn the knob back..... is that the same thing your talking about?

    Who you getting your base from?

    I am ok with center its elevation I am having difficulty with.

    You have lost me already, could you take it a little slower for me? Not that sharp with all this math yet /ubbthreads/images/graemlins/smirk.gif /ubbthreads/images/graemlins/crazy.gif

    Harrakhan, i've been studying this reticle ranging stuff for several years now, and the best system i've ever seen is sort of a combination of the TDS system, and the mil-ranging formula. TDS used his "ballistic reticle" as a ranging tool by using 1 of the stadia lines as the "main ranging unit", and then the others were calculated as simply a percentage of that main ranging subtension in inches, or cm., whatever measuring system u choose. To better ubnderstand it u have to begin thinking of the mil-ranging formula as really a "stadia-ranging formula" since the formula simply describes the relationship between stadia subtensions vs. target size vs. range. Here's a link to an article i have on the web, titled, "Tactical Ballistic and Ranging Reticle Analysis" that describes all my research to date. There r a few mistakes in the article that should be updated soon, but the concepts r sound. Refer to Item C) 1 + 2 Reticle Rangefinding-- www.ottllc.com/specialtypistols/sp20.pdf

    Here's a copied portion of a Sniper's Hide discussion referring to the Nightforce NP1-RR reticle (the 1 with all the circles in it)--

    As far as the reticle ranging goes it's set up for 9", and 18" targets @ the highest magnification. Looking at the website it shows the 1st circle is 9" in diameter @ 300 yds. That means the 100 yd. subtension should by 3", with the baseline to step measurement @ 2X that or 6". Now here's the fun part about reticle ranging-- the best system that' i've come up with is the "mil-ranging formula" that is really not milliradian specific-- it can be used for any stadia-stadia subtension out there (plex, ballistic reticle, custom reticles, AND NP 1-RR CIRCLES/STEPS). The 1000/36 factor in the mil-ranging formula is simply the dot-dot subtension in inches since the factor can be simplified to 100/3.6 (look familiar-- like maybe 3.6"/100yds?). Now simply calculate the other circle subtensions, and then punch them all into the mil-ranging formula to use the ranging system for any size target u want-- like this--

    9" 400 yd. circle = 9/4 = 2.25" @ 100 yds.
    500 = 9/5 = 1.8"
    600 = 1.5
    700 = 1.29
    800 = 1.125

    Now, just punch all these figures into the "modified mil-ranging formula" like this for say a 7.3" (Leupold Varmint Hunter reticle's std.-- if i remember right)pr. dog--

    Circle 1) 7.3" x 100 yds./3" (300 yd. circle)/bracketing gap target fills in tenths of that total gap--1.0 =
    7.3" x 100/3"/1.0= 245 yds. for the 3" bracketing gap "300 yd." circle.

    Circle 2) = 7.3 x 100/2.25/1.0 = 325 yds.
    Circle 3) = 7.3 x 100/1.8/1 = 400
    4) = 730/1.5 = 490
    5) = 730/1.29 = 570
    6) = 730/1.125 = 650

    This system is very flexible, and allows the use of just about any reticle subtension for any tgt. size-- INCLUDING THE BURRIS BALLISTIC MIL-DOT--either dots, or line stadia. Fact is, u could actually measure the reticle subtension @ any range and punch it into the equation.

    Hope this helps some. Let me know if it doesn't-- this stuff can be quite confusing-- took me more than a year to figure it out.

    Judging by the chart posted earlier, it seems to be a inchces\yards rectule as apposed to a MilliRadian/Metres rectule.

    I would prefer not to comment on this rectule as I prefer to support tactical/practicle rectules rather than commercial interests.

    Well thanks for that 700, I'm not a commercial interest, just a regular guy tryin to improve and get a little support from my peers and betters.

    Apart from telling us your personal preferences, your comment adds nothing to the question so why post?
