I've been thinking about getting a phone scope to record my shots threw my spotting scope. What are you guys doing to help spot when shooting solo?  Plus it would be nice to have some proof of my shots for all the haters to mope over lol.

I typically shoot alone so I use a GoPro Hero4 with a Phoneskope adapter on my spotting scope to spot my own hits (or misses :rolleyes:). This lets me control the camera from my phone without getting up. I can start, stop and review the video to make necessary corrections and download the video straight to my phone if I did something awesome that I just have to show somebody. :chuckle: Everything else I take home and edit on my laptop when I get home.

The only real issue with taking video through the spotter is that you lose a little image quality in the process. I can film in 1080p through a Swarovski spotter, but the image quality still degrades pretty quick.

That's a good point. I wonder how clear it would be with my phone.

You'd still get good video quality since most phones take pretty amazing video these days.

You could make that work. This is 1200 yards through a NF ATACR on 25x with an old Iphone 5


Quality optics and perfect conditions make everything look better. :chuckle:

I've got an iPhone 5 as well but my scope is a viper PST.   Pic above is focused at 735 but you can see my 400 yard targets on the right.

Little more wind practice today. Still don't have a phone scope set up yet so just a few pics. 5-25 mph wind today. Thumping rocks at 845-877 yards. Think I may have found an area to shoot 1300 which about where I go sub sonic. I've heard that crossing that transonic regin can play havoc on a bullets flight. Any input on  >transonic range???

Thought I would share a little bit of what I found on transonic region flight.

Transonic Ballistics Effects Explained by Bryan Litz
What happens when the bullet slows to transonic speed, i.e. when the bullet slows to about 1340 feet per second? It is getting close to the speed of sound, close to the sound barrier. That is a bad place to fly for anything. In particular, for bullets that are spin-stabilized, what the sound barrier does to a bullet (as it flies near Mach 1) is that it has a de-stabilizing effect. The center of pressure moves forward, and the over-turning moment on the bullet gets greater. You must then ask: “Is your bullet going to have enough gyroscopic stability to overcome the increasing dynamic instability that’s experienced at transonic speed?”

Some bullets do this better than others. Typically bullets that are shorter and have shallow boat-tail angles will track better through the transonic range. On the contrary, bullets that are longer… can experience a greater range of pitching and yawing in the transonic range that will depress their ballistic coefficients at that speed to greater or lesser extents depending on the exact conditions of the day. That makes it very hard to predict your trajectory for bullets like that through that speed range.

When you look at transonic effects on stability, you’re looking at reasons to maybe have a super-fast twist rate to stabilize your bullets, because you’re actually getting better performance — you’re getting less drag and more BC from your bullets if they are spinning with a more rigid axis through the transonic flight range because they’ll be experiencing less pitching and yawing in their flight.

As I learned it 2800 fps, 1800 fps and 1100 fps cause "bumps" to shooting accuracy.

I read about it 20ish years ago and don't remember where I found it.

Probably due to using a G1 profile for a G7 shape, you have to adjust the BC being used as velocity changes to get a good matching curve that follows the actual drag curve.
"That's the reason we pay $25 for a recoil lug made by a professional instead of one for $0.50 made by Micheal J Fox using a dremel!"
