Good Day All. I have a GMT-300BLK can that I’ve owned for a few years and have shot lots of supers and subs out of it. I was reviewing subsonic 223 loads to consider if I stayed on the low end of the load charts, would the pressure hurt the can. The load I am considering uses Hodgdon BL-C(2) and lists 41,900 PSI. I would of course use the correct upper and have the thread adapter as well.
Has anyone done this through a “dedicated” 300BLK can?
Thank you all for the anticipated responses, even if they do come in somewhat colorful.
