Theoretical Velocity & Preasure

[dj70]

I can't find any data for the following load. Can anyone help?
190 gr Serria Matchking .533
81.6 gr & 81.4 gr H1000
Remington 700P 300 Win mag 1 in 10 rt. twist 26"
OAL round 3.459"
Alt 2000 29.92
Is there any other data I need here?
Thanks

Re: Theoretical Velocity & Preasure

If you'd sign up for your Fooking Sniper's Hide Decoder Ring you know the answer to these questions.....

But just to help you out Lad, 81.0 grains yields about 3000 FPS at about 62000 PSI, give or take.

Unless you run a strain gage pressure is just a guess anyway.

If I were running a JBM table on that load to get some theoretical drops, I would use 3000 FPS, and a scope height of 1.75" plus the data you have, should get you close.

And I would use the bullet data marked Sierra 190 Matchking (Litz) that uses a G7 BC, rather than the G1 BC your planning on using.

Best of luck,

Bob

LOL, I'm not sure what you mean by this but...
I was using 3100 fps in the JBM table and my scope height is 1.5. I'll try using the 3000 fps and the G7 data and see the differences between the two.

After I see how these group and check for pressure signs, I'll probably move the projectile out just a tad.
Thanks Bob.
