Anyone measure the BC of the JSB .25 Kings in an FX barrel?

Hi all, quick question, I just wanted to know what BC you all have measured out of the FX STX barrels. I used the BC measured by ChairGun to make scope tape, but when I re-zeroed my gun for 30yds to use the scope tape, but when I shot for 50yds I was about 3 clicks off. 
Thanks, PlinkForFun

 Go out and shoot at a known distance either shorter or longer them your 0. Aim at a spot and shoot 3 shots, measure the distance in drop or elevation from your p.o.a. Next play around with the BC until the p.o.i in inches on CG matches with what you measured earlier. There's your CORRECT BC AND YOUR SET TO MAKE YOUR TURRET TAPE. THAT BEING YOU HAVE THE CORRECT SCOPE HEIGHT AND FPS Calculated!!!!

Probably be between .044 and .048 even .051 believe it or not depending on muzzle velocity. THEY SHOOT SO WELL!!! Can possibly be as low as .037 shooting in the 770fps. Not an ANALytical guy here so just guessing off of the TOP of my head here since they do a hair better (sometimes opposite) than the Benjamin domes.

Like Redick said nothing beats real world shooting then labeling your turret the old fashioned way. 

I was off by About one inch drop at 100 yards depending on scope height guess that was not exact bit still within a 2 inch margin.

I allow strelock pro to input data. Am I wrong?

Thanks guys. I played around with the BC on ChairGun and I had to go up all the way to .0500. For the tape to match up what I had at 50yds. I’ll also try to measure the actual BC later today. Thanks
