Bolt pressure

[Toranaga]

Hey, I am doing a little project with my friend on a mag, and I was wondering what is the pressure that moves the bolt forward, is it 65 psi?

So if I didn't have a sear holding the bolt back, and i didn't have a spring, what amount of pressure would I need to put on the front of the bolt to stop it from moving foreward.

Thanks,
Andrew

I think you have somthing like 60-80 back there depending on what velocity your shooting at.

thank you for that information.
