    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    farmerbrown, Flight762: Sight height makes absolutely no difference to Spin Drift from the perception of the scope. :( @JL: I'm in Cape Town, South Africa... we use the metric system. Some of the variables I have used are in imperial, merely because of the sources that I got the data from...

    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    The atmospheric variables above are giving me a Density Altitude of 4600ft, which sort of put it at a yearly average of somewhere between Denver (DA:5800ft) and Las Vegas (DA:3400ft)... which seems a bit high for general US usage (as per 'Tactical's initial comments). I'm still no closer to...

    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    So the reticle indicates Spin Drift in Mil at: 1.82 Mil = 0.148 2.98 Mil = 0.1985 4.41 Mil = 0.2525 6.14 Mil = 0.343 8.23 Mil = 0.426 10.77 Mil = 0.5455 and with the new inputs I'm now getting: 1.82 Mil = 0.06 (difs 0.088) 2.98 Mil = 0.09 (difs 0.1085) 4.41 Mil = 0.14 (difs 0.1125) 6.14 Mil =...

    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    Right, we're getting there: Temperature: 25c Barometric Pressure 29.77 inHg Altitude: 2500 ft Wind 32.1 Zero: 200m Barrel Twist: 1:7 Gives: -1.818 - 403m (vs 400m) -2.977 - 500m (vs 500m) -4.415 - 600m (vs 600m) -6.149 - 699m (vs 700m) -8.245 - 798m (vs 800m) -10.767 - 898m (vs...

    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    0.86 Mil = 303m (vs 300m) 1.82 Mil = 395m (vs 400m) 2.98 Mil = 487m (vs 500m) 4.41 Mil = 580m (vs 600m) 6.14 Mil = 672m (vs 700m) 8.23 Mil = 764m (vs 800m) 10.77 Mil = 858m (vs 900m) ... so elevation is a huge amount better, probably just need a tiny temp / altitude adjustment and we're there.

    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    lol... looking back at their wording, we're all right. The CMR-W 5.56 spec sheet says: "5.56 NATO/.223 Remington - 62 gr. - 2970 fps - 50 meter Zero" The generic manual states: "For best results, the CM-RW reticle should be zeroed at 200 meters, allowing the center point of the reticle to also...

    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    Doh... I multiplied rather than divided. Yeah, the wind is certainly a factor here... we average 9-14 knots during a month depending on the time of year, with sustained gust of 36-45 knots. Many thanks for the input.

    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    Yes and No... ;) ... the manual that you're referring to is their generic tactical manual and covers a large range of their scopes and reticles. The specific CMR-W spec sheet indicates a zero at 50m, which is what you're basically doing with a 300m zero by using the 300m mark at the bottom of...

    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    Redmanss & Dustoff82: Normally I would agree with a 3-9 optic, etc, but this is a 1-6 optic designed for CQB and mid range, and increasing the zero past 100m pretty much makes the scope fairly useless. It's also a scope that is favoured amongst the 3 Gun crowd, so max 'application' distance is...

    Rifle Scopes Leupold CMR-W 5.56 reticle - ballistics reference variables ???

    As many of you have guessed, I rather like these ballistic wind based reticles, as if you get them set up right, they are incredible. ...problem kicks in when you can't get them set up. :( :confused: :( :confused: :( So I've been de-constructing the CMR-W and rebuilding it in excel, and I've...

    Rifle Scopes MK6 1-6 Reticles

    I've completely reconstructed the CMR-W reticle in excel for my AR. Yes, it is both a vertically and horizontally ballistic reticle... BUT... you can get it to operate on pretty much any caliber, just ignore the distance 'numbers', and rather work off your own rifle's ballistic distances at...

    Rifle Scopes Question for Scope on 260REM build

    I've got a S&B PMII 4-16 on my AIAW .260 rem... now going to be upgrading to S&B PMII 5-25.

    Rifle Scopes 1-6x Optic for 3gun

    I had exactly the same question recently, and ultimately went with the Leupold Mk 6 1-6 CMR-W. It's got a known eye-box illumination problem... but I guess it indicates when you head is not in the right place... ;) (note: practice mount and cheek weld) I suspect that the Trijicon VCOG is going...

    Rifle Scopes scope parallax question

    It opens the scope up to the entire precision Air Rifle market, where 25m is required. ...it's one of the only scopes on the market that actually fills that hole.

    Rifle Scopes Bushnell reticle swap?

    What type of shooting are you doing ? I personally really like the TReMoR2, it's actually easier to use than the H59 for dealing with targets of different ranges in a similar heading in that you only have to calculate wind once, whereas the H59 you'll have to calculate wind for every shot. Then...

    Rifle Scopes TReMoR 2 Reticle Manual/ Explanation

    yeah yeah.... my first post here.. ;) The more I read/research about the TReMoR2, the more I'm inclined to get it on my next scope. The vertical Mil setting is a no-brainer, (we're all soo used to that now) but those Wind Dots are damn smart. Think; if you've got a Practical Long Range...
