Home Forums Hunting & Shooting Long Range Hunting effect of altitude in trajectory

BBerg, your original post shows you are not yet thinking in the terms of a long range shooter. You seem to have the skill and most of the equipment.

Why not make the few adjustments necessary to take your long range game to the next level?

No, I was not trying to "have fun on you." What I was trying to do (at first) was give you the tools you need to figure out the answers to your questions on your own rather than asking someone on the internet to figure it out for you.

And even with those tools laid out for you, you sat back and let someone else figure out what your new drops would be.

And yes, asking what your new drops will be at your high-altitude hunting location is the same as asking what your new point of impact will be. Posting pictures of dead animals can't change that.

I was under the mistaken assumption that someone who spends as much time and money on hunting as you do would naturally want to take personal responsibility for something so basic.

That's what it comes down to.

It seems like Berg is just a little better than me, so I am interested in everything he writes.

I am trying to break through the 500 yard hit anything barrier and [sure hit] hunt at 600 yards. I have been trying for 5 years.

As I read a lot of postings similar to this one I never cease to be amazed at the amount of people that have problems placing a shot where they wish at distances of 500 to 600 yards. Either they don't know the first thing about proper marksmanship procedure or they have 'boat anchor' material for rifles!! Here's a simple hunting rifle in .308 Winchester that is a 'hammer' at the above distances!

Sorry R, but that rifle is obviously messed up, look where the bolt handle is!!

I love my .308 too. Accurate, and a pleasure to shoot.

Berg obviously doesn't know about Ballistic AE or own a "watch".

He can always post a thread and ask what time it is........

You guys are just crancky. Bunch of women. Go out and get some...

I'm not cranky. Up yours though.

'Watch' Out now..... got the time too....

Tidings of comfort and joy to you, too. Hope you have a very good season - where ever and whatever you may be hunting.

Thank you, and same to you. I'm eating some fresh elk shank stew right now, nothing better IMO.

Damn, that spot looks familiar. Fax me the altitude and coordinates so I can confirm I've been there. If you don't mind.

Altitude is on the watch.... Canada is 4 miles north....

I'll need longitude too.

Fresh elk is, IMHO, indeed very hard to beat. Good for you.

This year at Quemado, I was hitting the steel out to 300 yards, consistently without changing the zero, from Arkansas at 240 ft to where we were shooting at around 7500 ft. I did not think to check on paper, just shot. Using a 7mm-08 improved and 120 gr ballistic tips. Maybe Dennis will chime in with the actual distances. miles

Here's a pretty good online ballisitic calculator. You can manipulate elevation and zero distances amony many other things.

Aside from atmospheric pressure, Another factor going from 3000 feet, up to 12,000 feet in elevation may be your muzzle velocity. MV may be lowered a signinficant amount by the drop in powder temperature.

Using Reloder 22, and Reloder 17, I see approximately 1 fps loss in MV per degree Fahrenheit.
