CZ 75-B is jamming

[JB]

I have a 75-b that has been great it's eaten everything i put through it till now . The bullets that I'm using now look between a semi wad cuter and a RN bullet

Need more info:
Factory loads? Details?
Reloads?
Bullet weight?
Plated, lead?
Powder type & amount?

Describe the jam.

How does the loaded OAL compare to the OAL where bullet engages the rifling?

 

[Trigun]

I think you are using FP( flat point), they have different OAL than round nose, the easy way is to compare with a factory ammo such as winclean.
