How do semi auto shotguns run when not shouldered correctly?
What about a rig that was originally set up for lead that might barely run right w steel?
Easy to screw up?
Gas guns will run fine. Its the inertia spring in the bolt that requires an offsetting force to allow the spring ro compress and bolt to unlock. Most steel loads are high brass and have enough powder charge to run most any semi auto. A lot of the 3.5" guns struggle with the handicap clays loads though
