- I'm' 69 and had a left rotator cuff job and a reverse replacement on my right shoulder. I lift weights everyday but I don't know how long my shoulders will hold up.
8 pumps is 677 fps and 14.56 foot pounds of energy.
10 pumps is 754 fps and 18.06 foot pounds of energy.
12 pumps is 785 fps and 19.57 fpe.
13 pumps is 805 fps and 20.58 fpe.
14 pumps is 823 fps and 21.51 fpe and a second shot available at 539 fps without pumping. If you don't take the second shot you will only have to pump about 9 or 10 times to get the same speed as a 14 pump shot.
With a stock 392, 8 pumps is about 650 fps.
If you want to shoot harder at 14 pumps, it would take a heavier hammer spring and/or a lighter valve spring.
Pictures coming soon.
I'm losing money at $275 plus half of the shipping cost $20.
CONUS only. I can't do anything like Paypal. I'd like a USPS MO.
