How will elevation affect my ballistics in Colorado?

[kjeff91]

So I'm going to be getting a 6.5 creedmoor (probably a Tikka CTR) and I was wondering how elevation will affect my shooting. I do antelope hunting and will probably participate in some PRS matches around 6300 feet and go for deer around 8000 feet. Will there be a noticeable difference between these two as well? I will probably be getting the 20" barrel since my Spewar 762 should be home soon.

yes,

you'll either need to print your data via Density Altitude Charts for the changes or use an App that includes a solid Current Conditions couple with zero conditions.

You're zero will not change, but your dope, especially beyond 300 yards will change by noticeable amounts.

I just did a free training video on this

Awesome thanks! Is there an app for android that work well for adjusting all of this as well as recording previous outings?

 

[Lowlight]

they all have zero condition and current conditions,

Whichever App you want to invest in will give you basic data, but before guys jump in and tell you to buy a super expensive kestrel know, when you true them, with us moving from CO to sea level the kestrel will not be correct and have to be re-trued for the new location. On average by about 50fps the trued data vs new data will be off, I see this every time.

You can even get Strelok for free on Android and that will help you when traveling to different locations.

I was wondering if you were in Colorado for the video you posted! Good to know on the kestrel. Is that something I should invest in sooner than later?

 

[Lowlight]

you just need a kestrel that gives you DA you do not need a full blown one with software, it certainly helps, but it depends on your budget.

I would say if you want to go the full kestrel route, find an AB 4500 model, you can find them used pretty cheap and at times the different kestrel sites have them discounted.

But anything that gives you DA is good, there are even apps that do it, you just need that one number.

I have used the Android App Shooter in CO for many years hunting and recently got a Kestrel 4500. I shoot at 5000 and 8000 with the Chrono to check my data, and temperature sensitivity. When I hunt Deer, Elk and Pronghorn (I know, but they are technically Pronghorn regardless of what CPW says) from 4K to 10K, my data has always been spot on. Just now learning Kestrel, but I won't bet against what Frank said.

I have seen .2 to .5 mils different at 600 yards depending on the variables, with my .260 Rem.

Oh good to know. How much was your kestrel? And do you mean 4k to 10k in elevation?

I am not sure, I got it on sale and with a coupon, like $350 or so. I got a 5700, not a 4500, my error. Yes, 4 to 10 thousand feet.
