Hi.
What load of gunpowder VihtaVuori N150 it is needed to utillize for achievement speed 2400fps-2900fps?
Bullet 180gr.-200gr.-220gr.-240gr..
Barrel/cal. 30-06 , 22" (steel 4140)
Your recommendations.
Thank you for an answer,
Kristian.
P.S.
Gunpowder VihtaVuori N150 http://www.vihtavuori-lapua.com/n150-8lb-p-220.html near on properties to to IMR 4350?
I plan to utillize bullet 65G , 65C and 65B
http://www.woodleighbullets.co...llet%20List%203.html
and
bullet 308177HV198

Kristian,

If you know the Laua website, why not look in the Lapua/VV load data published on there??

Regardless of whether anybody happens to be able to cite VV N150 load data for the exact bullets you hope to use, you'll still have to work up loads in your own rifle.

VV N150 is possible for .30-06, but it will be better for the lighter bullets. For the bullet weights you mention, N160 - or even N560 - will likely be the better choice, at least in terms of muzzle velocity. N150 should be faster than IMR 4350. N150 is often compared to powders such as RL15 in terms of burn rate and application.

Hi Mike.
I am in a position to apply ONLY the gunpowder of SUNAR it is an analogue VIHT N-150 ,-initial weight of gunpowder for heavy bullets from 45gr.+.

My calculations:
I knowing that limits SAAMI specifications for the rifles of caliber 30-06 make ANSI PSI 60.000 - ANSI CUP 50.000
for 300Win.ANSI PSI 64.000 - ANSI CUP 54.000.
I put a question about high and critical speeds which can be utillized for a barrel/cal. 30-06 , 22" (steel 4140).
PSI 60.000 - 4218.42 at. coming from that critical pressure is in a barrel- I put a question about high and critical speeds,-coming from that critical pressure is in a barrel/cal. 30-06 , 22" (steel 4140)-4218.42 at..
E(max. and critical)=mv2/2
For example:
for a bullet which I want to utillize CGC Bullet .308" 177gr HV on barrel/cal. 30-06 , 22" (steel 4140) stalling speed will be 2805.12ft/s
at critically maximal pressure PSI 59786.4.

Have you reloaded before?
Read a reloadingmanual before you try so you dont harm yourself.

Consequently admittance on speeds for this bullet is possible from 2625ft/s to 2738ft/s.
Middle speed can make 2700ft/s,-
