Default 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.


JSB 15.89
2000 PSI Fill

1. 792
2. 792
3. 795
4. 796
5. 791
6. 800
7. 803
8. 803

10. 812

21. 802
22. 798
23. 792
24. 781
25. 773
26. 762
27. 751

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
Dave
