Impressive shooting. Any updates on this new bullets, different loads?

I got a 375 cheytac semi auto that Im just starting my first loads on. Hopefully next week I can unleash it.

Re: 2 mile shooting -3500 yards
I am also very surprised at how good you can see at 2 miles... here in Cali where our long distance shooting occurs from Oct to May (due to fire risk closure) and thus cooler, we still have heat wave mirage at one mile and the target is fuzzy at the edges even with my PMII S&B at 25X. To double the distance seems like a futile effort and then my S&B elevation turret would be way past maxed out I believe. Also my Terrapin PRLF won't range out much past 2000 yards if it's a sunny day.

Cal...he's in CO where they have wide open spaces and altitude.

Re: 2 mile shooting -3500 yards
altitude sure helps. I think we are shooting at a DA of about 3k-4k feet at our shooting location. This will be year 3 of working on mile shooting... be interesting to see if more practice will have improved us or have we hit the wall of our loads/eqpt.
My goal is to hit anywhere on that 24x24 cold bore first time I get to the location. If I can't hit it in 3 shots, then what's the point. I think this year I am going to re-chron my loads and compare several kestrels data and re-examine my SHooter BC inputs.

Re: 2 mile shooting -3500 yards
That's a good goal. Altitude helps, but so does dry air. The BLM areas I often shot in SoCal were very clear beyond a mile and mirage only became an issue in the hot summer sun. NorCal tends to have a bit more humidity, so I'm not surprised you have mirage issues.
For 2 miles shooting, seeing the target is obviously a challenge, but spotting splash is by far the most difficult aspect.

The molecular weight of water in a gas form is 18 atomic mass units (amu), as opposed to 32 amu for oxygen, and 28 amu for nitrogen.
Due to it's lower density, humid air enhances ballistic performance for a given temperature, and pressure.

That's counter-intuitive, but I'll take your word for it.
Re humidity vs mirage, I've found mirage more a function of temp than humidity. The BLM and ranges I am using are in arid and super hot areas off the I5, and rarely is humidity experienced there. It's even closed during the summer due to fire danger. And when it's super dry and above 75-80F, I start getting difficult mirage at 1600 yards plus.

Re: 2 mile shooting -3500 yards
I think Dogtown included temperature as a factor that is compounded by high humidity.
Not only are you combating a greater range of intermingling air densities, and therefore mirage, but with a temperature drop condensation can become an issue, and this will also compromise light transmission.

Re: 2 mile shooting -3500 yards
Yeah its a form one can.(Home made) I tested it with mill spec testing (B&K sound meter) and it tested a 129.5 dbl. A real pleasure to shoot. There are two cans I made in those pictures one 408 and one 50bmg.

Just wanted to add that Shooter for Android will go up to 5,000 yards but I have no idea if its accurate that far out. It has some Litz BC's for bullets and I believe uses JBM-based calculations.

Had no idea you could reach out that far. Amazing. I think I need to get out of the UK and come shoot some real rifles over here!

Ok the Channel Locks must have been used to pinch yourself, I know they weren't used on that rifle.

Lol- you are right. I laid on some cactus and had to pull a few barbs on my leg. Thanks for the painful reminder. Lol

wow, you use the white telescope to have your partner spot for you?

In the sixth picture is that a rat works big chubby muzzle brake?

If you could, 'splain to me how you get extra elevation by "loosening up your adjustable rings"?
Oh, and BTW, thanks for making me feel like small potatoes for 'only' shooting to a mile....
Seriously, that IS flat out awesome.

I have a set on my .50
