WHAT YOU TALKIN WILLIS????
Where and why this total fallacy about unsupported chambers REFUSES TO DIE is solely routed in IGNORANCE!!
ALL AUTO CHAMBERS are "looser" for reliability. The brass in the case Inherently within its design, has a web thats much thicker and stronger and withstands pressure limits within design perimeters. When these are exceeded THINGS HAPPEN. But its not the fault of the chamber or the forearm.
I have all three flavors of Glock 10mm... I have two flavors of COLT 10mm... I have multiple KKM, LONE WOLF & aftermarket barrels. I have ahot and tested many dozens of lods for decades and never saw a problem untill I got a Carbine assembly and saw the limitations of a unlocked blow back. Even this and the bulged cases where NOT A FAULT of a "unsupported" chamber. They where a result of pressur curves unfriemdly to the unlocked breech design.
I regularly shoot a worked up handload with a Cast 220 HP and Bluedot at just shy of 1200 from the G29 and 1250 + from the G40 6"!
ZERO NONE NADA BULDGE.
