The Lyman Cast Bullet Handbook #4 shows the .32 Winchester Special with a case length trimmed to 2.03" and the RCBS #32-170-FN gas check bullet seated with an overall length of 2.52".
The OAL of 2.52" results in the crimp groove being exposed. I have a hard time believing this is correct. 32 Winchester Special is mainly a lever gun cartridge and in a lever gun crimping like this would probably cause bullet setback under recoil.
If I crimp in the crimp groove, just underneath the front driving band I get an OAL of 2.48". This is what seems correct to me. Crimping just underneath the front driving band looks right and it prevents the bullet from going any deeper under recoil.
If you are using the RCBS #32-170-FN in the .32 Winchester Special please tell me where are you crimping? What is your OAL?
