Looking to see if someone would run some numbers for me.

6x45mm, 22" barrel
29.9gr H2O
80gr TTSX
COAL 2.335"

25.5gr cfe223 gave me 2690fps.

Looking for what powder theoretically will give me the best velocity.

Thanks in advance!

Thank you.

So if I'm hitting 2690 at 25.5 gr, QL predicted 27gr needed for that velocity. So would I just subtract 1.5gr across the board or is it in a curve, and I should subtract 2 gr or more from max and that will be similar to where my max should be? I'm not familiar with how it works, or I would probably have a copy of it.

That's awesome, thank you very much. It's a fun little gun but likes to heat up. Probably mainly due to the weather.
