Cricket 9mm is coming together

Tried .3531 today, picked up an average of 16 fps. Accuracy looked slightly better so Im stopping there.
Yeah, probably don't want to go any lower. I did some experimenting over the last couple of days. I went as low as .002 under groove diameter. Though velocity went up as I sized smaller, the velocity spread increased by a lot.
 
Been out for awhile with some family issues. Started my 31” tj today.

Great post. Thanks for answering the questions I had about your design. You might not have invented the balance valve, but you sure created an incredable design for this particular platform. Bobs vast knowleage with math fomulas he has put out there for us to use was a big help too.
You said it was a lot of work but worth it. After making one like your design I would agree, now that I'm at the worth it phase.
I doubt most of us could really appreciate what you've achieved. Huge power gains with some very small components of the right types of materials.
Hope to see the finished project sometime.
