      I would very much like to use your reticle in a Minox, it’s a damn shame no one in Australia cares to import them in to Australia and support Minox optics.

    Hey Thomas
    Do you still have your 6,5-284? Im going to replace my 308 by a 6,5 caliber. Still thinking about 6,5x47 or 6,5-284. But im a little concerned that the 6,5- 284 is a barrel killer. What would you recommend? I still have a 6,5*55 and im loveing it.

    • @THLR
      @THLR  6 лет назад +1

      I did not get 6,5x284 barrels for my R8, just the plain 6.5x55. I wanted to cut down on reloading. If you already have a 6.5x55 I don't see the point of a 6.5x47 unless you want a very, very high precision potential. For hunting, I can tell no difference between x55 and x284 and naturally x47 or 260 or Creedmoor would be same.

  • @BeneStarosta

    Very fine video series! And an interesting reticle!
    Could you please draw a scetch on your website or here at youtube explaining what AIM SHOT and AIM LONG means and where to find the brackets for light medium and strong wind exactly - I'm not sure where they are exactly but want to understand your reticle.

    • @THLR
      @THLR  6 лет назад

      Benedikt Höfl Episode 260 and 264 will give you some insight. Aim short and aim long is just an aid for shooting moving/unknown distance/fleeting targets. LIGHT is inside the bar, MEDIUM is the bar, STRONG is outside the bar. The wind brackets are designed to offer an easy solution for most modern cartridges (about 55% of what is produced) the first 4-500m where they all behave similar.

    Another nice video. Hunting animals, not plates, will one click be significant at, say, 500 yards?

    • @THLR

    "Shooter error, can't fix the idiot"
    Classic Thomas!
    But the system does work well.
    Is the top turret engraved? Do you have different turrets for different barrels?
    Or do you just have one scope per barrel? Is ask as some might not understand that the ret is useful for almost any cartridge.
    You just need to set up your calibrations as you have done here.

    • @THLR
      @THLR  6 лет назад +3

      Yes, I just had it engraved at a local shop. The values seems to hold for most modern cartridges. Looking at the high performance cartridge 300 Norma, there's not much difference between them in terms of relative change. The ballistic info is just cheap tape and is replaceable per cartridge. The reticle IS NOT cartridge specific, it is 100% MRAD and I have simply highlighted the smart Choices and it will work With any cartridge. Optimal performance (like thewind holds) will be for about 55% of the current rifle ammunition Portfolio found in stores, so every modern calibre will have a selection of cartridges that will perform "better" and be easier to use.

    • @onemanriflemaker3873
      @onemanriflemaker3873 6 лет назад +1

      THLR.NO I understand 100%.
      I think a lot of people turn them selfs upside down when thinking about external ballistics.
      When people understand the reticule they are looking through they become more confident.
      Where yours is so good is the fact that it isn't so specific as to limit its use.
      A ret filled with lots of hash marks is hard to read. Why would you use that in a hunting situation?
      Your reticule is the true hybrid.
      I will say it again. I think you have Nailed this mate!

    • @THLR
      @THLR  6 лет назад

      Thanks for that, very generous. I think it will be a looong time before this gains any type of widespread acceptance. But yes, it is as you say, people often loose themselves in ballistics. Shooting to say 500 meters really isn't a big deal and most modern cartridges behave very similar, so it will be the same working principle/ action required to reach the same result and only minor difference in initial setup to make it spot on. That is why the simplified windcall I use work so well - ballistics are so similar with a boattail bullet that you can easily "learn by fire" without needing to understanding the ballistics behind it (much like electic currents - I don't need a science degree to turn on the light in a room. Just show me where the lightswitch is. I leave building the components and wiring the house to the professionals).

    • @THLR

      There are some details I could have presented differently. For example, the silhuette scale and square could easily be removed (for the better if sales was important) as this was basically just an intellectual challenge to me (and comparison to other principles) and has no real use to me. With the exception of the cosmetic dot line at Y -5 MRAD, everything supports a decision process inside a relevant timeframe and is dimensioned to work at a sensible range of magnification for that task. We'll see how it goes.

  • @MrSkjaerbaek

    Hello Thomas. I am also shooting 6 xc. 1:8 twist and currently i am using 918 M/s as average for Strelock. Will the THLR Hybrid work well for my Caliber. What M/S do you have on diamond line. Thanks in advance. As always nice RUclips clips.

    • @THLR
      @THLR  6 лет назад

      I have 842 msec with the Norma factory ammunition in my short barrel. The reticle isn't designed to work with ballistics (it's MRAD based), it is design to support the DECISION you need to make the shot. The exact meter values and optimal settings for the different cartridges will be a little variable, but they are all very close as there really isn't much difference in the projectiles fall angle (approximately 0,02 degrees if I remember correctly). That means that allthough two full trajectories seen from from 0 to 1000 meters can be very different, the two bullets will travel along very similar paths IF they enter the swept Space With for example sight correctly set to 300 meters for both bullets. Examine the Scope settings in your Strelok. For example if you set zero to 300m, look at trajectory -1 MRAD height and you'll see the meter value for AIM SHORT, look at +1 MRAD AIM LONG and you'll see the meter value for AIM LONG. Set Strelok to zero 100m and use +1 mrad for AIM LONG, +1,5 MRAD for Heavy post etc.

      it's not really that specific. More of a general acceptance on the idea that external ballistics fall into a much narrower band of performance than a lot of target shooters wish to admit.
      It's a full milrad set up.
      So if you want to calibrate it. Calibrating your rifles performance at a given atmospheric circumstance will allow you to adjust to different circumstances in atmospheric climate! Atmospherics play a much bigger part in long range loss of accuracy (dependant on your own standards of accuracy)
      It why the v bull gets bigger the farther out you engage it.
      It's also why OCD type reloading is such a bad idea! That really only gives you a false sense of confidence.
      But confidence is a big part of long range shooting.
      Thomas has made a reticule and applied to a system where correction is still easy.
      So if it was me I would get as much external ballistic data as I could and then get the turret strips made up with the calibrated info!
      That make life a whole lot simpler.
      Your could get stickers to cover your specific drop for your rifle over a given value. but then but then you would lose your definition on redress to circumstance.
      You can have far too much information.

    • @THLR
      @THLR  6 лет назад +2

      There is a detailed instruction filmed on Vimeo, vimeo.com/ondemand/langhallsskytte2. Setup your desired trajectory every 100 meters (300-400-500-600-700-800 etc), write down the comeups. Change weather up//down 30 hPa, write down the comeups, same for temperature. Go back to original trajectory, set ballistic app to show every 1 meters (798-799-800-801-802 etc). Look at your notes and the comeups for the weather deviations, compare to original trajectory on ballistic app - write down where the the deviation comeup starts (e.g 785) and ends (e.g 792). THat would give that "significant" step a bracket of 15 to 8 meters (800-785 and 800-792). Repeat for all weather deviations you want to examine. Find the average value that will fit inside all brackets and decide at what distance you need to change the average value. A correction value for 400 meters will rarely fit inside a bracket for a 1200 meter shot. I find it easiest to keep air pressure significant at 30 hPa and rather change the temperature significant 5-7/8-10 Celsius to make them fit each other. Clear as mud? It is about 1 hour work first time, then you will be on easy street.

    • @THLR
      @THLR  6 лет назад +1

      Thanks Jim. A lot of people tends to blaim the equipment immediately. I have found that in the vast majority of cases, I am the biggest error. Looking at the turrets through the camera viewer or from the sides tends to make them a little hard to dial. I need to start double-checking the setting in order to have full effect with these demonstrations.

      Oh, on that aspect I COMPLETELY agree, the "nut behind the butt" is invariably the weakest link in the chain, sir. But even so, you do a darned fine job of showing us both how to do things, and how you do them as well. ;-)
