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.
