Last week in TN I simply used the rough estimator describe by Frank Galli of .1 MIL or every 100 yard for a 5mph wind. So I held .5 at 500 and .9 at 900. Worked very nicely. A bit easier than using a Kestrel or calculator. Might want to check it out.

I just use the frank galli. Method. Use the first number in the g1 bc and that’s your 5mph bracket double for 10 triple for 15. He explains it in his pod cast. It works for me and is always .1 from my ballistics calculator. Or right on. Check it out.

Awesome video. Good tips. I predicted you would hit too far left. I think you guessed the wind spot on in this case. I believe your constant is incorrect. With 147g hornady match, my 500 yd constant is 18. 300-400yd is 20. 800-1000yd is 17. At 500 that would be a wind call of approx 2 moa instead of 2.5. Regardless your load, I wouldn't think it would calculate that much of a difference in constant. (D x W)/windcall = your constant; if the data in your ballistics chart is input correctly.

Crybaby Blues I can’t argue with a math guy. Not that I don’t “want” to. I simply can’t. lol I got my constant for that gun and ammo from a DMR class I took with The Site. Jim Kauber is an ex Seal Sniper. I’m not saying you’re wrong or that he’s infallible, just that he knows more than me and I’ll take his word for it. lol
@cmhwilder4 жыл бұрын
Jim can be 10x better than me and still make a small mathematical error. lol Not being argumentative, just trying to fix one of your variables. We know its not a constant, because the number shrinks continuously with increase in distance. So we choose a midway point (constant) for practicality. You reverse the math in your Ballistics charts using your wind formula, ie: 7x5=35/2.5moa=14......7x5=35/1.96moa=17.85...etc, to get your "constant". IF you input your Ballistics chart wind drift data adjusting for a 1 mph wind. No ego homie, just tossing ya a tidbit. It will also help you find your constant at any distance you want. Its just reversing the math is all. My hornady 4dof says .28moa at 1mph at 500 yards. 7mph is .28x7=1.96. So 7x5=35/1.96=17.85. I round to 18. Even if yours varies slightly based on your location, temp, barrel length, powder-load, etc it won't be but a few hundredths of moa. A constant of 14 is entering into .308 territory. And we know 6.5 creedmoor smokes .308 in wind deflection.

@@PrecisionRifleNetwork The math is easy, explaining math is hard lol. I edited the last comment. Trust me, man, use 18. You'll tighten your wind holds I promise. 6.5 creedmoor deserves it. Distance x Wind then divide by your windcall (moa) and you'll get your constant.

Hold up, wait a minute... i feel like im missing some information in order yo try this myself. You get the wind by using the chart and reading vegetation, i get that. Then you multiply by a wind constant that at your distance was 14. So i assume that constant changes depending on range? Do you have a chart for that? Then multiply again by .3 for mils... plus whatever value the wind is blowing from.
@PrecisionRifleNetwork6 жыл бұрын
Hudson as I said in the description, google search for wind constants. You should easily find a bunch of articles and charts. The reason I worded it like that is because some people say the constant changes based on some variables and some people say you use one constant for everything. I was trying to acknowledge that. I personally just use 14 for everything because #1, I don’t need a wind constant at all below 300 yards. And #2, from 400-1000 my constant works fine. It might and possibly should change beyond 1000y but I never shoot that far.
@isaachousley3253 жыл бұрын
Theres an old wwii rifle training video that describes guessing wind speed and determining wind holds. The formula for the hold was (A*B)/10= number of windage clicks, where A equals the range in hundreds of yards (ie 500 yards=5, 1000 yards= 10, ect) and B is the wind speed in mph. This essentially gives you the wind hold in moa as the windage knob on garands is 1 moa clicks. I believe that the 10 is the constant for m2 ball ammo

I want to know how to do it the old fashioned way because lets face it,,, anyone who has half a brain and has used technology when the rubber meats the road has always had that technology fail on them... Can anyone point me to a spot where the actual step by step mathematics are taught? And I am not talking about the idiotic 1 moa is 1 inch at 100 yards crap.. Im talking about taking all your known data, doing the math on paper and adjusting your scope appropriately.. I have watched a million videos and for some odd reason no one ever explains the math.. Whether they dont know it and use a machine or dont want that info out there I dont know,, This is the closest I have ever seen anyone come. But I believe that if you want to be the best shooter out there, you need all the info.. Any help would be greatly appreciated..
