Sierra Heavy TMK 6MM Testing

[Jordan Smith]

“OR” elevation, temp, pressure, and humidity.

Just pointing out that it’s just temp, pressure, and humidity needed, assuming you use absolute pressure.

I use most all of them. Shooter is what I personally choose.

Was just looking and didnt see either 77tmk, 108eldm, 103 eldx, or any 224 eldx in their bullet library.

Back to the thread topic...


When did it go from "large 6MM TMK" to "entire line of high BC TMKs"

Kind of all at the same time. The heavy 6mm was the catalyst I suppose as it had been pushed for, for so long.

and will you/others be testing the other new ones in the lineup?

Yes.

I dont generally use bullet libraries. Input the bullet info and BC and go.

That’s one of the best cross section jobs I’ve seen. What tool? I use my grinder and vice like some kind of mongrel.

A mill. It’s not perfectly down the center due to just clamping in a vise.

This is the way. I’ve seen so many bugs and discrepancies with prebuilt libraries over the years in the Apps/Engines that I don’t trust them.

I was referring to absolute pressure using shooter. It’s just temp and DA



I know AB has temp, pressure, and humidity then just converts it for you to show the DA at the bottom.

Siding for pressure input? I’m not sure what you’re asking.

Generally solvers are set up to run DA and temp or Elevation, pressure(HG), humidity, and temp.

Sorry I meant what are you guys inputting for pressure into JBM bullet stability. It only asks for pressure and temp as environmental inputs

Input the pressure for the lowest elevation areas and temps you plan to shoot in.
I used 27.75 at 30* which is close to 1000DA
