Stock Discovery string.

My new pro chrono just arrived and I decided to test it out with this disco

I still have to put some lead on the paper but what I'm thinking of doing is detuning it a little. I would like to get closer to 35 plus shots for target shooting at the range. Maybe in the 16-18 fpe range. Think its doable ? If so what direction should I go in first.

i don't reaslly know --- don't have a disco .things i might try though ---a weaker hammer spring ,stronger valve spring,valve volume reduction or restict the tp .maybe any combo of thoses or use co2 :D ;) :)

[eric]

as a side note think AOA sells a regulator forthe disco that might help also

[grumpy]

I was thinking of a regulator. I'll let you guys know how it comes out.

Yeah, let us know for sure! I may need one for the one I picked up for the wifey.

I ended up getting rid of this disco, wish i didn't, and replaced it with a Hi Pac 2260. I got a chance to run a chrony string but just have not had the time to post the numbers yet.

I will say that with the Hi Pac and 1 extension I got more shots then a stock disco, just with less power and more FPS spread. I think the spread can be tightened up some with some spring tweaking. Will update when time allows.

Thanks
