Well I bought a RADARchron and 100 reballs off of ebay. Then I built a 24x14x14 chrono back-stop and did a bunch of shooting in my attached
2 1/2 car garage
I shot around 300 reballs during my test cycles and many different spring changes. I was wondering, how good can I get my gun (a Proline) shooting consistently on fps readings? The best I could get with a certain spring/washer combo was:
Low = 277
High = 292
Range = 15
average = 284 (19 shots)
This was done with a lose paint match in the barrel (reballs are smaller than .679), Palmers Stabalizer set to 800, 15 to 20 seconds in-between each shot, a mark on the barrel to ensure consistent RADARchron location temperature in the garage was at 58° and a consistent rythum with each shot.
Here are the results:
Let me know what you think.
Started with a Splatmaster, moved onto a Nelspot 007, then came the Autocockers, then "reliability", a STERLING Pump, next was a Bob Long defiant then a PM7. As of now I have 4 Sterling Pumps, 1 Phantom for SC and 2 Spyder's one is a future Spump.
