    Night Vision Vortex Impact 4000 Rifle/Rail mounted Range finder???

    Honestly, unless you only own 1 precision rifle, I can't see doing anything other than mounting it to the spotter. Who wants to remount and rezero the thing everytime you change rifles, and who can afford one for each rifle?

    Night Vision Newb looking for clip-on advice and info

    One can generally rely on the manufacturer saying it has a clip on mode. If they don't, it does not. As stated, they need to be 1:1 at 1x, and have some way to align the screen.

    Night Vision Newb looking for clip-on advice and info

    1 Day optics are compatible in that the magnification range must work with the selected thermal device and mount high is within range. 2 For a thermal to act as a clip-on device, it must have a true 1:1 output mode and either a lens system ot screen alignment mode to get a boresight zero. 3...

    Vectronix Bluetooth Adapter

    Anyone happen to have a Vectronix BT adapter for either the Vector IV/PLRF or the Vector 21 that I might borrow for a bit? Need a unit to test code for Field Firing Solutions and they appear to have gone out of stock everywhere. I could also use a PLRF25 BT early non-AB version, but that's a...

    Field Firing Solution (FFS) new Android release?

    OK, import of a KML file for targets and FFP's in now on the list. That should allow for integration to ATAK or Google Earth for targeting.

    Field Firing Solution (FFS) new Android release?

    The G1 from your muzzle velocity range is the starting point. You may need to alter that by a few percent after you find velocity /drop at range.

    Field Firing Solution (FFS) new Android release?

    It's more or less the same. If possible on 4DOF, use the 4DOF calculator and the custom drag models, then at 3/4 or so of max SS adjust the Axial Form Factor is need be. Otherwise the standard G1/G7 calculator is tuned like anything else. With FFS, we use G1 and then make long range...

    Field Firing Solution (FFS) new Android release?

    I have 4DOF, and if they are both tuned to the load and rifle they are within .05 mil and 10fps to 2300, which is my nominal test range limit.

    Field Firing Solution (FFS) new Android release?

    The above being said, if there are any Android UI experts out there that would like to contribute ideas on the UI, feel free to send me notes or sample files. The project is currently Xamarin Forms, as we had some issues with MAUI.

    Field Firing Solution (FFS) new Android release?

    I I always found the Windows CB software very difficult to use in the field, very klutzy UI for me. I'm a Windows guy, been using and programming it since the beta. I'm finding programming for Android a HUGE shift, and I don't begin to understand all the UI options. I want a UI that lets me...

    Pressure vs velocity

    If that is happening what you have is a powder that is much too slow and is having so much unburned material ejected into the suppressor that it is detonating inside the can. The old Pressure Trace system from RSI had an article showing the high chamber pressure from just such a situation, but...
