Re: NIghtforce Ballistic software..

Never realized that Eaglet. I would have thought that updates would be free. With the possibility of upgrades requiring a fee, if the upgrade involved sweeping modifications.

As you know, I'm using Patagonia Ballistics LoadBase 2.0. Soon to be 3.0. Another reason to count my blessings.

Re: NIghtforce Ballistic software..

Phorwath, the last time I checked, altitude was included in atmospheric conditions, along with barometric pressure (which obviously changes with altitude), relative humidity, and temperature. The chart I referred to was to include the results of shooting the rifle at different altitudes, different temperatures, different relative humidities, for different distances. Perhaps I should have said that in detail the first time. There is no substitute for sighting in your rifle at the altitude you intend to hunt. Every single ballistic program I have used (and I think I have used them all) gives you incorrect information sooner or later. It is just the nature of the beast.

Not sure where you're coming from. I've got a pretty good handle on altitude, atmospheric pressure, and atmospheric pressures corrected to sea level (barometric pressure).

I can't imagine that you're suggesting that we shoot our rifles iteratively at different altitudes, temperatures, and relative humidities, over different distances in order to prepare a chart of logged data that will be used for future hunts. If a person were to hunt from the same blind over an entire hunting career, I suppose one could proceed in that manner. Then you'd only have to account for changes in atmospheric conditions.

I purchase and use ballistics software precisely so I don't have to do what you're suggesting. It can account for any temperatures, atmospheric pressures, relative humidity, angle of fire, wind, spind drift, coriolis effect - down to the minutia - but at least the important ballistics affecting factors so that all one has to do is confirm the rifle is still properly zeroed after travelling to a hunting location and go hunt. The ballistics software will modify the POA as necessary for the conditions under which the shot is actually being taken. If you're saying it's a good idea to confirm your rifle's zero prior to the hunt, or that one needs to confirm the ballistic software predicted drops with range time - no problem. But if you're saying shoot in different temperatures, atmospheric pressures, relative humidities, and angles of fire either at the home range or at hunting camp prior to going hunting in order to develop a chart prior to beginning the hunt? A lot of my hunts would be over based on the allocation of time that would be required to generate these charts. The game would be scared out of the country, I'd be out of ammo, and have a barrel that needed to be cleaned of copper build-up.

Unless I'm getting the wrong interpretation from your post, my question would be - Why do you buy the various ballistic software programs that you say you've purchased and used if you're not going to use them to modify your POA under different conditions of fire?

Re: NIghtforce Ballistic software..

If all someone is doing is hunting under conditions and at the distances one normally shoots at in hunting terrain, they can get along fine with a ballistic program used in the manner you suggest. What I was suggesting is intended for use by someone who wants to wring the maximum possible ability out of their rifle to hit exactly where they are aiming on varmints or game animals at long range. If someone practices a lot with their rifle and load over a period of time and at different locations, and keeps track, they will find that they have started to compile such a chart anyway.

I do very long range varmint hunting inn many different locations, and I shoot large game in many different places, at greater distances than most people seem to (really long cross-canyon shots, where there is no ability to get closer before shooting without scaring the game; after shooting, you can get as close as you want).

I bought the various ballistic programs to find out how well (or, in some cases, if) they worked well enough to use in any way for this. I found inappropriate algorithms in some, and I found that the calculations in at least one were based on one rifle and load in each caliber, fired, in some cases, only one time. I found that some of these programs would have you miss completely a lot of the time, and I found that at least a couple were pretty good. I think that some of the program manufacturers have done an excellent job of providing a program that can be used by most people, under the conditions and in the manner in which they shoot, and I found, that, for my purposes, they are of only limited use.

Re: NIghtforce Ballistic software..

Interesting.

I can't speak for anyone other than myself, but once I've confirmed my ballistics software is accurately predicting my actual drops out to 1000yds under the specified atmospheric conditions existing on the day(s) I've field tested it, I then trust it to modify my POA for any other set of shooting locations/conditions I encounter.

I haven't come across any better method of predicting proper POA when traversing the wilds of Alaska in search of game, and taking shots from altitudes, locations, and angles that I may have never encountered before, and may never again duplicate while shooting at game.

Re: NIghtforce Ballistic software..

Again, for the kind of shooting you are doing, obviously, the ballistic programs you are using do the job for you, and that is great. If I was only shooting out to 1,000 yards, I could manage quite nicely on big game using the same programs that you do. Small varmints at such distances and beyond, however, are another matter entirely. Some of the varmints I shoot have a vital area that is only about 1.5-2" across, and on these, at these distances, a 1/8' error can give you a complete miss. I do a great deal of shooting, and keep detailed records on every shot I take, so that I can hit the varmints I want to, at the ranges, and under the conditions, I want to hit them. No ballistic program that I have yet seen gives precise enough data to be of more than ballpark use for this, although for that, they work just fine.

Good luck, and good shooting!
