Guys here is a real quick video that I did on my personal rifle comparing the FWB 300s with an original Dual spring setup compared to a single spring setup I show groups and velocities
referred a guy to you from RFC who was looking for a FWB 300. I figured he should save himself some potential aggravation by getting a rebuilt one from you.
Not sure about Texas show this year, but hope to make it again.
Joe, do you still have the velocity data on the old spring that was in the gun?

I have 3 FWBs, all with the original springs. My Mini is the fastest shooting 7.33 pellets at 655 fps. The other two 300Ss are around 615 to 625. I've also noted that the abient air temperature has some affect.
I've re-sealed one of the 300Ss, but didn't replace the spring. Maybe I should have, but I hate to tear it apart again.

I do know it was shooting about 650 or so with 7.33 pellets . I changed it out mainly to get another crack at it with the new double springs I had just got in .This speeds you are quoting are just about right . It wasn't until after I made the video I realized that the speeds I posted were wrong . I was using chrono connect app which is actually really good but I entered yardage wrong ! The speeds are off by about 50 fps on average.It was a rookie mistake ') . Genuine 700 fps FWB rifles are far and few between . Especially after the new spring kinda takes a set.
