Alright, I bought this spring kit in hopes to make my gun more air efficient. With a harder spring, I should be able to lower the air pressure on my Palmer's Stabilizer, and maybe make the gun work a bit better.
I got the spring kit, and decided to test them out with my Pro/Carbine. The Pro/Carbine uses the same stock spring as a 98, A-5, or X-7.
So, I'm out at a field. I set the Pro/Carbine's velocity to 290 +/- 5 FPS using the original stock spring. One at a time, without airing down the gun, I swapped out each spring. I tested the velocity of each spring verses the stock spring, without touching the velocity adjustment. Here's what I got.
Stock Spring = 280 FPS
Green "Ultra light" BT Spring = 250 FPS
Blue "Light" BT Spring = 255 FPS
Black "Stock Equalivilant" BT Spring = 255 FPS
Silver "Hard" BT Spring = 265 FPS
Red "Ultra Hard" BT Spring = 260 FPS
As you can see, the velocities produced from these springs was horrible. The Heaviest spring shot slower than the next lighter spring, and the Stock Spring shot faster than any of them. DON"T WASTE YOUR MONEY!!!
