it seems like it took about 10 minutes of pumping. I was out of breath and my heart rate was elevated!
That said, I suspect I will acclimate to that and build the correct muscles fairly quickly. It is not for the faint of heart for sure. I could see some folks tapping out and going a different route pretty quickly.
I think i did 40 shots and it was still above 2000PSI. so i'm guessing around 50. That said I suspect that I could easily keep shooting below 2000 with a little slower pellet speed (probably wouldn't even have to adjust the POA.
@Carolinatlc would have a better idea, i'm a total noob.
my concern is that I will have to get smaller targets! I was pinging the 1" steel from 25 yards pretty easily and don't really have room to stretch the distance too much more. Honestly the piston gun with open sights hits the 1" target 1 out of 4-5 shots and hits the 2" target 4 out 5. I pinged the 2" steel 10 times in a row going without going slowly.
