I think so, others say they don’t work well. The New style plastic spin pre crimp caused me trouble in my two 600 JRs 10 & 16 G with short kits and used with Cheddite hulls.
Way I run the brass pre-crimp, fixed it does not spin. I have to align the fingers with the hulls crimp fold. Slows things down a bit but crushed crimps do too. I never loose a hull on crimping now.
