I used 14.5 gr.of old Herc 2400 and won't function as a semi auto. So I upped the charge to 15.7 gr. (the next size up in my Lee measure) and while it shoots splendidly it still doesn't quite eject the brass. I do not want to go any higher with 2400, and actually I'd like to stay at this velocity as it does not damage my steel plate targets. Can I buy a bolt spring and start removing coils until it will function?
