Somewhere in the forum I thought I read that heavy loads, e.g. buckshot, don't even need gas to cycle the action.
Which begs the question:
Does Position 1 of the gas plug shut off the gas to the puck or does it just minimize the gas reaching the puck?
Note, there is lots of discussion about what it takes to cycle low brass/low energy rounds, e.g. number of gas holes, size of gas holes, etc. However, what does it take to cycle buckshot?
