300prc

[JPS]

I want to try the 250gr ATip in my 300 prc and need some guidance regarding max speed with N 570.
Included in the packaging is a airsickness bag just in case one can't stomach the price per shot.

DD,
Laat jou freebore toe vir die 250 A tips?

[Diesel Dog]

Kan net nie die rondte uitwerp sonder om die slot uit te haal nie.

I wonder if Dale still follows this thread?

[Dale SH]

I'm still here.

[Diesel Dog]

What does your crystal-ball say about the 230 bergers and the RL26?

DD

[Dale SH]

Give me all the data, I am too lazy to go back in the thread and look it up.

Bullet code ?

[Diesel Dog]

'

[Dale SH]

I think you just broke my crystal ball.
It just went tilt.
It told me that you have 3.60mm of the bullet shank in the neck.
It told me that your burn rate is ridiculously high and it also told me that your pressure is at 72700 psi

[Diesel Dog]

I hope you can fix it a lot of people rely on its predictions. Serves you right for taking such a long holiday and leaving me on my own !

DD

[Dale SH]

I really have to question those velocities,
Realistically you should be running about 2750 fps with this combo,

[Diesel Dog]

Replace the bullet with 230 a tip

[Dale SH]

Don't have it in my database.
Please give me length of bullet.
Small diameter and length of boat tail.

[Diesel Dog]

44.89 mm length
5.7mm bt length
6.27mm base dia

[Dale SH]

Thanks.
What is your TPL with thee bullets ?

[Diesel Dog]

97.2mm
I GAVE THE INCORRECT BULLET INFO ABOVE:-[The data was collected with the Hornady bullets and not the Bergers.

DD

[Dale SH]

OK so with the A tip data you still over pressure and your burn rate is still high.
Clearly this cartridge falls into major overbore category and the long bearing surface of these bullets also doesn't help.
With your existing data, my crystal ball which is still smoking a little bit, tells me that you should be at +- 75.5 grains for 2788 fps and 61500 psi.

[Dale SH]

The positive part is that my crystal ball now says you have 7.55mm of the bullet shank in the neck.

[Diesel Dog]

I was getting 2835fps at 95 mm tpl with 230 bergers and 80.4gr n 560.
THIS THING IS ALL SHOW AND NO GO!!

[Dale SH]

Give it to me as late Christmas present.
