Quoted:
I would wait til I experienced an actual fte before I started to be concerned about gas issues....lots of things can slightly change your ejection pattern and at the end of the day who really cares where it ejects as long as it clears the breech.
My MWS ejects to the 2o'clock position using Hornady 165 SST Surper Performance. Hunting last week after I shot a doe a buck comes out I pull the trigger and nothing, I have a case that didn't eject holding my bolt open. That broke my heart. My fault also for not checking the gun after the every shot when I had the time to do so.
I have shot 100rds of that ammo and so far only had that one issue with this MWS.
Other important fact it's the 16" CL flavor.
Edit: more info that may help or not. The casing that did eject went out the small hole of the blind and landed infront of it. Same as in the range my brass always lands on the floor infront of the table with this MWS.
Accuracy is amazing tho and as long as I don't get any more FTE's I'm very happy with the weapon.
