I would like to start a discussion from reloaders who have a suppressed .300 BO on the AR platform and are loading the NOE 247 grain cast boolit. I have these questions which I think, if answered, will benefit many:
1. I have read that when you setup an AR to shoot subsonic it will only work for 200 grainers plus. True/False??
2. What is your C.O.A.L. for the NOE 247 gr. boolit?
3. Is the upper groove in the boolit considered to be THE proper Crimp Groove and therefore a workable C.O.A.L. (which is within SAAMI specs)
4. Did you have any chambering issues during load work-up?
5. What is your successful configuration with respect to Bolt/Buffer/Tube/Spring/Gas Port/Barrel length??
Anything you can contribute within parameters of discussion will be very much appreciated.
