I think the increased blowback caused by the suppressor is increasing the bolt carrier's rearward velocity and causing rounds to eject at 1 o'clock or worse and those rounds are hanging up inside the receiver where it jams the rifle up as the bolt travels forward. I need to slow the bolt's rearward velocity down and bleeding off gas at the gas block seems like it ought to do it. We'll see. It's on the way. If not, back to the drawing board. I'm not wanting to change the load as it shoots really really well in all of my guns.

The suppressor increases the gas pressure and volume, there is not a blowback effect in the bolt cycle.

Your suppressor effectively lengthens the barrel and causes more gas dell time on your pressure chamber in your bolt carrier.

Have you looked into the suppressor bolts now available? They have a suppressor/no suppressor adjustment and reportedly work well.

Most semi-auto guns run well on one type of ammo. They can be set up for whatever you want, but trying to get one to run on everything is a lesson in frustration. Set the gun up for suppressor only use is optimum .
