Shooting at Angles: Rifle Shooting Technique - NSSF Shooting Sportscast

[bunnysniper22]

are all that cosine's you wrote out a constant ?

[ClecknerNSSF]

@bunnysniper22 Yes. The cosine is a function of the angle. The cosine for 40 degrees is 0.77 regardless of the application (in math class or on the range). These numbers are published in many places and are available on scientific calculators with a "cos" button - you can just enter the number of the angle in degrees and press "cos" to see the cosine.

would that be reversed for uphill shooting?

[ClecknerNSSF]

@rusky1971 Nope - I point out in the video that it is the same up or down.

[TheMinnesnowda]

amazing tuts man lol im also ex military, i have noticed how you mean to say something hooah, and stop, and correct yourself lol.. thanks for the info sir.

[CNDshooter94]

Holy I never actually thought something I learned in math would help me in shooting:D!

[SsjSned]

great videos in the older vids when you said you werent gona even try drawning a animal it really had me laughing. I learned alot thanks

[6HARIS]

Awesome.....great informative video......keep it up

[HunterKiller308]

extremely well done. thats alot of information broken down in a very comprehensive way.

[1234lukerr]

awesome video as always

[ptlm60]

That's a lot of math lol

Bullets drop with time, not with angle or distance travelled. Gravity is a constant, applied to mass with time. This video does not explain this.

[ClecknerNSSF]

@pirate0jimmy This video is not, nor was it intended to be, a physics lesson. What it does is show new shooters how to adjust for angles. In the video I explain that the bullet does not truly drop different with angle since gravity is a constant - however, the bullet does drop away more or less from its original path depending on the angle.

[dvdrwsor]

Very nice video. One thing tho... What about if I'm shooting uphill ? I understand from your logic that the bullet is being pull to earth harder so the true range is longer than the actual range. The question is : where can I find a chart with cosine for both uphill and downhill angles? I guess the cosine for uphill will start from 1.01 and beyond. I do have a rangefinder that has a built in inclineometer that shows the angle in degrees. Thank you for the videos and taking the time to respond.

[ClecknerNSSF]

@dvdrwsor I mention in the video that shooting uphill at an angle is the same as shooting downhill at an angle. The bullet is not being pulled "harder" to the earth, gravity is just pulling at a different angle. There is no cosine for up or down - the cosine is a function of an angle regardless of that angle's direction. For example, the cosine for 20 degrees is 0.94 up or down (if it were 1.01 as you sugest, the angle range would end up being longer than true range). Good luck!

What a very good explination!

[SmokeDogNY420]

I got a degree in math and the whole last part was boring and complicated. Buy a rangefinder or get closer. Not rocket science.

[ClecknerNSSF]

@SmokeDogNY420 I appologize if it was complicated for you. As I mention in the video, the second part only applies if you are going to range the target's distance using mils. I agree - a rangefinder is a simple solution. However, it is important to know how to use other methods - kind of like learning how to use a map and compass even though you have a GPS.

[bogart6348]

Ryan, very informative video, like all your others. Clear and easy to understand. thanks

[ClecknerNSSF]

@bogart6348 Glad you liked the video!

[sniprzkitty]

Top Tip: 500 yards straight down, man, just drop a rock of that cliff, kill your target stone dead, save ammo ;)

[ClecknerNSSF]

@sniprzkitty Good point. :)

Now another purpose for my Suunto compass with clinometer.

[ClecknerNSSF]

@AboveMediocrity2010 I used to use my Suunto watch for the exact same thing!
