Advanced Long Range Computer System

[Triggerfifty]

Just a lead, T.H.E.I.S. (Tactical High Energy Impact Systems), Warren Jensen or Lost River Ballistic Technologies and myself (THEIS is the owner of the .408 design) are going forward with the development of an advanced tactical calculator/computer for extreme range shooting. The general format will be in the question / answer format... example

Ammo?
Range?
Slant angle?
Air Temp?
Air Pressure?
Ammo Temp?

Advanced features will be correction for Coriolis effect, automatic spin drift and if we get out way, an remote system for automatic data dump of the above inputs directly into the computer.

There will be multiple inputs for windage and direction, plus automatic remote dumping for a wind meter at the gun position.

Am also working an advanced rangefinding concept working with GPS... can't say more about that. Any features that you guys might want to include that I haven't mentioned. PLease let me know. All is possible..

There will be NO digital readouts on the optics. The gun system will not be altered. This is a stand alone calculator.

Thanks,
Dean

Is this system for use by Tactical shooters in a combat situation, or competitve shootes firing extreme long distance from a inextremis firing line ?

Good to see you again Gunny,

It's for whoever wants to use it. I believe that ultimately, it will be tailorable for those who order. From basic model to super-sophisticated models that are passive with an Offset GPS rangefinding system.

Hi Triggerfifty!

Your advanced tactical calculator sounds pretty interesting! Several years ago, I considered designing and manufacturing a programable powder dispenser/measure and some other large market handhelds. The powder dispenser would compensate for variations in case weight which results in MV variation. Someday, I may get the time to design that constant MV automated powder dispenser.

Your tactical calculator will have to be easily and quickly programable for it to be useful in current competition. Current competitors only have 1 minute per round. During the minute the target will be down about 10 seconds, and if you're fast another 10 seconds will be lost loading and sighting. So, a fast shooting competitor will only have about 40 seconds to program your calculator, read it, and make sight adjustments.

Take care!

Carl

I talked with one of the computer guys today and he actually said that the programming could be setup to constantly update data and elevation/windage data every 3 or 5 or 10 seconds or whatever. Alot would depend on the level of automation for the different inputs.

It could also be setup so that only the changes that need to be entered would be entered, all other data would assume to stay the same... for example getting a change in the data for the winds going from 6 mph from left to right to 8 mph from the tail. Automatic correction for headwinds and tailwinds will be in the system.

Not too important for matches, for 2000 yd shooting though, those tailwinds in the test in Idaho counted for about 3/4 MOA for elevation at times.

Carl, what's your email address. I'll send you a copy of the Idaho test, some photos, and a sensitivity comparison of the .4o8 Cheytac vs the other military sniping cartridges.

Good to see you again,
