 If some of you probley already know Im into long range shooting with rifles. I always wanted a ballistics computer like Horus with Atrag which with properly inputed material is good for 2000 yards plus. Well to justify the price at $600.00 it was always been the last on my list of things that i wanted. Well fast foward to last friday. Ive been working out alot lately ive ran 36 miles in 9 days and been lifting a bunch of weights. I thought it was time to purchase a I Pod to listen to music while i work out. I was looking on I tunes today and found a I Pod program called Ballistics FTE which is a ballistics calculator for the I Pod. So i did a google search and found that it has GREAT results and it just as accurate of a program with all the same features as Horus for only $19.99!! So I bought it and so far its simple, has all the same and even some better features as Horus but at a small percentage of the price. Im very happy I cant wait for the Munden to get here to try it out at 600-700 yards!

If you have a smart phone you can get a app called "shooter". Works great and its only $9.99. You can preview it if you google shooter ballistics. You can save multiple guns and multiple loads for each gun. It even uses the gps on your phone to get temp, wind and direction, atomospheric conditions . Also allows your to make graphs too.

Good luck with it, I did see maybe on a long range shooting site or youtube someone was shooting an ultramag ?cal.. and was trying out the ipod software and it wasn't working out for him.
He was shooting 500 to 800yds and the # of clicks was not matching up with what he was shooting.
I hope that won't be the case in your situation, your post made me remember that video of that guy.
I will try to find that video and post a link for it.

This program was part of JBM which as some may know is also very accruate. THe most important thing is making sure every input is correct. This program even has a log for atmospheric conditions when you sight in versus current conditions. It makes graphs, had a program called HUD which you can switch to once all the input is in. Hud is good to 1000 yards and can be in 25 yard increments and is very fast. It also has line of sight that automatically compenstates. I love it so far

Oh you can also put in rate of twist, it also figures coreolis effect. Essentually it has all the features Hours Atrag does and even more for only 20.00!

Always good to hear someone working out, keep it up and you may be able at 77+, to say your still at, I am bum heart and all.
The 13th of this month will be two years since getting four stents,The first three years are the most important. With a little luck I'll be chasing Moose and Brownie across the Tundra when I'm 80.....MAN PLANS......GOD LAUGHS

Mark,
What does it say about the coreolis effect if anything? I have been wondering how that effects bullet flight. I don't have an I phone but it sounds like I need to get one.
Please let us know how it works in the real world.
Thanks,
Greenhorn

Coreolis effect really doesnt matter until long range use like 1000 yards plus so for muzzleloaders its really not needed. You have to enter latitude and longitude and it will automatically adjust.
Think of coreolis like this. There is two stationary things, first the shooter then the target. When you shoot and the bullet is in the air the earth is still rotating on its axis. So coreolis will take in account the earths rotation on 2 given stationary targets. THe further you go out the more pronounced it will be.

if i remember correctly some say a high power rifle @ 1,000yds will be around 6" coreolis effect average

6" possibly, I guess it would depend of the time in flight. If the .308 win was being used I could see that plausable

Actually, at a 1,000 yard match, you don't get involved with the CORIOLIS effect. You simply adjust your sights to hit your target. It may be there to some degree but you just don't notice it. If my bullet is striking the berm 6" from the clay bird I am sighting on, I just click my scope. It could be wind, Coriolis, the bullet, mirage or whatever. So as was mentioned? Don't be concerned with you ML. Now Rossman would be more concerned with his artillery shells which may be sent a few miles down range ;D

Thanks for the replies on my "coreolis effect" question.
I wonder do they have left handed rifling in australia,lol?
Just kidding thanks Mark for clueing us in,

Finally recieved my set of Farrell rings and base today. Wow although expensive and a little heavy they are built like a tank! I have no worries this scope isnt going to shift anywhere. Beautifully machined and very nice finish.

6" possibly, I guess it would depend of the time in flight. If the .308 win was being used I could see that plausable I would think that you could make the coreolis effect a no-effect by shooting straight east or straight west. The effect is caused by different spots on the surface of the earth moving at different speeds. Spots at the higher lattitudes (N or S) move slower than spots at the equator because a complete rotation covers a smaller distance in the same amount of time. |

DBinNY,
I agree,so a south to north shot or vice-versa, would be most affected and anything in between that would be a vector of the "effect".

DB has the Coreolis effect down pat. If it takes that in to account you would have to input the direction you are shooting at at what latitude. In the artillery this is all part of the firing solution with the modern computing systems, different from the days of "charts and darts".
To many guys get their effects wrong. You have gyroscopic drift (spin drift) which can depend on bullet length (longer projectiles experience more gyroscopic drift) and spin rate (faster spin rates will produce more gyroscopic drift). You have the Magnus effect when cross winds work with the gyroscopic drift. And then you have the Poisson effect when the bullet keeps it's nose up during the downside of the trajectory curve and wants to roll off the air cushion.
