I've read that cylinder gap should be .002 to .006 mm. Â I understand that in theory, the smaller the gap, the greater the power of the bullet. Â I've read that at .002, carbon can accumulate affecting gun operation. Â
Â
In reality, how crucial is it? Â Does it really affect power? Â Does it really affect gun operation?

Thanks in advance for the edjumaction!

Hey 95:
As you probably noticed in the other thread, I set all of my Dan's at .002. I have never had any carbon build-up. However, I thoroughly clean all of my guns after each range session; so that may make a difference.
I use .002 because of the supposedly better performance and accuracy. However, this may just be psychosomatic; there may actually be no difference at all. I just do it because I hope it's true and I want all the performance I can get.

I set mine at a smaller gap for pretty much the same reason Zoomb stated, but I usually get mine closer to .003" gap. I've only seen a noticeable difference on my high-mileage 15-2. That gun likes to spit at .006 & at .003, it spits noticeably less.
One of these days I'll send it home to mother DW, so it can be taught some basic manners again...no spitting!

I have most of mine set close to .002 also, but I set all my heavy duty shooter closer to .005 just so I can shoot a LOT and not have to clean.
