If that is correct then I am about 50% oversize and it would have significantly over pressure not under so don't understand the weak ejection. Double checked the ejector spring vs. a new one and it's good.
.093" on CLGS 16" barrel in 5.56 or 6.5 Grendel is way oversized.
That's why you're having the problems you're having I suspect. Cyclic rate is too fast, which explains the stovepipe malf.
