Yeah, I'll go match rifle.
See what that one does.
What's a... What would a grain weight be for that?
For a charge?
Oh, gosh.
Let's go 20.
So your powder, your pressure max is 27,800 PSI.
Move in.
That's at 20 grains.
So that's about... Oh, I got to reset this.
I've just had to mess with it.
Now I got to change it back over for meters.
There we go.
Looks like, yeah, that velocity, your pressure max, your move in, looks like your velocity is about 2,300 feet per second.
That's low.
That is.
There's 2,700 feet per second with 8,700 PSI.
That looks like a load ratio of about 90%.
Burn propellant is about 97.5.
Effective efficiency percentage is about 30, so you'd want to kind of fine-tune it at 25.
