Can anyone tell me how to measure the force normally required to close the bolt.without a round, on a Ishapore 2A?
What would that measurement be?

If you're talking about the force required to turn the bolt down, it shouldn't take much.

Not exactly. I’m asking about the force required to push the bolt forward against the cocking/firing pin spring.

According to the service manual:
The weight required to pull the cocking
piece to the half-cock and full-cock positions shall
be 3.2 to 4.1 kilograms (7 to 9 pounds), and
5.9 to 7.3 kilograms (13 to 16 pounds)
respectively. These weights are checked with a
trigger test scale engaged on the head of the
cocking piece. Weak striker springs shall be
replaced.

This should be the same to close the bolt.

Thanks so much !
That’s exactly what I needed.
I’ll look for a service manual of my own.
