How do you calculate power factor?

[Tomcat]

I want my 45 reloads to make major. I have a crono, what is the formula to get the velocity with a given bullet weight?

Thanks,

Tomca

Re: How do you calculate power factor?

PF = bullet weight x velocity

PF/bullet weight = velocity

PF/velocity = bullet weight

That help?

Major is 165 or greater.

One small correction:

Power factor = bullet weight x velocity / 1000.

The "/1000" is important!
