rounds sticking in chamber

[Flewis]

Interceptor, how much did you have to cut the chamber and what was the final length? How long of a cartridge can you chamber?

Thanks. I have a M1S upper on the way and hope I don't have to do this.

Can't answer your question accurately about the ammount of cutting. I just watched the process, gunsmith did it. My load length is 2.215", chambers/extracts fine.
