I’ve used my Kadet 2 on a SP01, 75 BSA, 75 BD, and a PCR but don’t really use it that way on a PCR. I just wanted to see it on the PCR.
. If you are running a CGW red 13# main spring it won’t be very reliable setting a round off. A 16 or 17 pound is needed for that. That being said if you have an extended firing pin (from CGW) in your SP01 don’t forget to change the 16-17 # back to the 13# before you shoot a 9mm .
You will risk a very real chance of puncturing the primer.
Not a good thing to do
