OCW for Jump or Jamm Bullet

[gsg5pk]

For load development in .308 win

I normally jump bullet around .020"

Firstly, I start load test with each load of min from berger manual to test where start the pressure sign and stop beleow that.

Second, I load 6 rds of each to test group, AVG, SD, ES



In case that I gonna touch or jamm, do I need to start a new ocw? Because many comment that when touch or jamm bullet, pressure increase rapidly.

Re: OCW for Jump or Jamp Bullet

Any time you change one variable you need to verify it's effect on accuracy/pressure.

I would recommend you do a short OCW test to see how the change affects the groups and pressures.
