Hey guys. Unfortunately I don't have a chrono so I was hoping for some generic info at best. Fx wildcat .25 now shooting heavies 33.95 gr. not sure of fps or bc. any info will be greatly appreciated. Thanx

Eddie,

I don't tune my wildcat "yet" so I know a stock wildcat shooting 25.4 gr jsb. At around 910 fps has a bc. Of .036 . Just wondering if anyone knows if I shoot a 33.95 gr jsb without any tuning if they would know the fps. Or the bc.?

BC should be roughly around .05 or close to that. You can somewhat estimate fps based on pellet drop. Enter your zero range then shoot at a further distance. Measure the drop and then play with fps in chairgun till it matches up with your drop. Much easier to just buy a chrono. They aren't expensive and are a very valuable tool!!

Thanks ajshoots. As a matter of fact I was just on Amazon looking at chronographs. Thanks a lot

I just tested the 33.95 king heavies today with my regulated FX Royale 500. I average 775fps(45fpe) at the barrel and 713fps at 31 yards. Plugging in all the other info (altitude, etc) I get 0.048 for the BC. Since the FX Royale and Wildcat share the same barrel, your's would likely work out the same (BC I mean, the fps might be tuned differently based on the hammer spring adjustment and regulator setup, etc).

FYI, I average 898fps (at the muzzle) with the regular 25.4 kings which works out to ~45fpe as well. So, no real difference in energy between the regular and the heavies at the muzzle, but the higher BC will help down range.

Thanks deroosea for the data. Ill plug in the numbers and see what I see but I'm probably going to have to bite the pellet and just get a chronograph. Its nice to know there's good people on this site willing to help others. Thanks again and thanks for everyones good wishes with my back getting better. Happy shooting everyone.

Hey my friend, it seems we have the same problem. im even a bit anxious because with my strelok ballistic app it makes only 600 fps for my change in POI reasonable. unless im doing something wrong... if u manage to measure the fps in your wildcat please let me know.

Although I don't yet have a chronograph, the data sheet I recieved from AOA with my rifle from their testing showed my fps average of 903 with the 25.4 gr pellets. I also used a chrono app on my android phone which showed an average of 900 fps. My wildcat is .25 . Not sure if .22 is any different. From what I've read on posts here about the .25, I've seen fps from 880's to 910's with the 25.4's. As far as the 33.95 heavies the chrono app showed fps from 810 to 788. I know its not nearly as precise as a real chronograph but its in the neighborhood.
