chrony readings

[Phantom 631]

Mine is a Combro Skot

 

Just had it rebuilt and recalibrated after a slight accident with a pistol turned the thing into an expensive 3D Jigsaw puzzle

 

I trust it The only thing I don't trust is the serial cable, but only because I don't have a standard serial connector on my laptop, so I have to run it through a Serial to USB converter and somewhere in the software driver for the converter, the readings on the comp are different to the ones on the display. I went out last night into the cemetery for the night. Because I'm using the Crosmans now instead of the FX, I printed the trajectory map using the data from the Combro and put it on the gun. Using the LRF and the data on the Trajectory map, I was taking headshots on woodies out to 50 yards and bunnies were also accurately head shot bar one kit that jumped up as the last of the pressure on the trigger let the pellet go

 

Regarding the recoil, nope it will not affect the readings

i might test my rifle with a certain pellet on the combro and then ask the gunshop nicely to do it on theirs with the same pellets, then if mine says different reading then will i be able to get it sorted.. ??

example my gun with pellet X combro says 10.5 and gunshops chrono says 11.5... id rather trust theirs, would there be a way to change mine .. re-calibrate it???

 

also im prety new to chairgun pro but it seems good so far, once rifle has bedded in and settled down then i find best pellet and get reliable power readings and measure scope- barrel height and all that technical stuff il have a play around and see what my aim points are going to be.

its zero'd at 30y at the min and on 12x mag every mildot seemed roughly 5y intervals.. from just shooting some targets at different ranges.. (when i did the 59y group from other thread)

 

it seems quite flat trajectory with jsb tho, probably be even better with a lighter pelet im guessing..

 

anyway cheeers mate

My local gunshop says for the combro to turn it off ,take batteries out to recalibrate itself ..how true this is, il never know, because I don't own one , Atb, keep legal

Skot,

 

If you have the original Combro, you can recalibrate it to it's original factory settings by removing batteries.

 

If you have a mk3 or 4, you can adjust the calibration to match any other that you feel is more accurate, ie have it done at the gunshop or police FAR. If the Combro does not match the other, you can alter it so that it does. Useful

Then every shot that is fired should match up with the other chrono.

To check, put on your combro and pell details or just have it set to FPS then fire it through the larger chrono so you get both sets of readings for one shot
