Q:

.25 jsb heavys.

Hi guys. Any of you using these in your rm3 matador?
What ft per second are you shooting and do you know the ballistic coefficient of these?i want to try these. I have ordered some but I would like to put the data in chairgun app and see the difference between the jsb kings and the heavys.
Cheers.

Ok. Just a quick update.

Shooting kings =927fts
Shooting heavys =805fps

Will do more tests Monday.

Please keep us posted what you achieved with a factory configuration.

Fair point.
I don’t fancy altering the reg on it. What sort of speed will it shoot at left as it is? Mine is shooting at about 927 with the Kings.
I will soon know. They should arrive in the next few days. Just fancied trying another pellet to see if accuracy can be improved.

I have shot them. I turned the regulator up to 140 and slung the MKII at 920. I really think the .25 Matty is not designed for that kind of power. Slinging a heavy that fast is really pushing the limits of the gun .
