I’m looking to start tinkering on my S45 and ran it over a chronograph for the first time today. This is a cheapo Amazon chronograph, so I might be returning it for another eventually. Here’s the first run, from 4400psi to 4100psi shooting 170gr Mr Hollowpoints:
1. 797
2. 797
3. 795
4. 794
5. 790
6. 783
7. 781
8. 773
9. 773
10. 763
11. 762
12. 761
I haven’t had the gun for very long and the only change I’ve done so far was swapping out the front tank to a 1100cc tank, for a total of 1600cc of air. 1100cc front + 500cc rear.
So here’s where I have a few questions for the pros. I’m well aware my tuning options for this gun are limited, my only real goals would be to iron out the descending shot curve as much as possible while keeping a decent # of shots with the huge onboard air capacity I have. I’ve shot ~50 shots or so from the 4500psi max fill to the lowest recommended pressure of 3000psi! I bought this used off of here and when I received it, the gun was cocked. Who knows how long for, but would this have weakened the hammer spring enough to reduce the shot velocity? I always keep it decocked now. Would a stronger spring bump up velocity at the expense of shot count? I have seen a youtube video of a guy who really digs deep into the S45, to great results. If anyone has any tips or has experience or done work on this particular gun I’m all ears. Thanks.
