What was the issue with running it? Were your cases sticking? Mine run as easily as a typical bolt rifle, but faster. Fishdart also posted a while back about sticking cases. Wonder why some do and some don't...?
I've only seen any sticking with the 30 HRT...
I'm not sure why bigger cases tend to be stickier.
My guess is more friction from more surface area of the case, and increased thrust expanding the case more tightly into the chamber and binding the bolt, but not sure, and I only have experience with that one larger case.
I have run my lightweight gasser like you describe and that works fine. The disadvantage is that I have to run it from the charging handle, which isn't too ergonomic. (Actually, I guess you mean running it semiauto - that works too - takes very little gas to run, but runs fine)
I guess the cases were sticking; tried it with 300 Blk and 223, and it just takes a lot of force to open and eject. With the 223, I'd have to bump the buttstock on the ground while pulling back on the bolt to get it to eject.
I didn't mean running the gasser as a straight pull from the charging handle; I meant running it as a semi auto, just tuning it to run on less gas through the gas block since I've removed ~8 oz of weight from the cycling parts (alum BCG and buffer with weights removed). Will experiment more with this setup.
