crusoe 1 Posted July 9, 2012 Report Share Posted July 9, 2012 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?

Mullet Man 2,114 Posted July 9, 2012 Report Share Posted July 9, 2012 Think about that for a second..... a gas operated firearm not needing gas to cycle the action?. Once you figure that out, you will have answered your own question. 5 Quote Link to post Share on other sites

In Law Enforcement we commonly use reduced recoil slugs and buck. Essentially these are lighter loads but not as light as say birdshot. In this case, the gas setting may need to be different from a full powered shell. mike Quote Link to post Share on other sites
evlblkwpnz 3,418 Posted July 10, 2012 Report Share Posted July 10, 2012 The carrier has to be pushed rearward, by gas, in order for the bolt to unlock. The regulator does not create and airtight seal above the orafice on the bottom of the gas block. Some gas still gets by the regulator and cycles the action. Quote Link to post Share on other sites

It takes the same amount of gas to cycle the action with ANY load, but with more powerful shells, the gas must be restricted (because there is more of it) to bring it to the level that will cycle the action properly. And that's why the correct setting is #1 with full power loads. That is the restricted setting, not "less gas". Physics. Edited July 10, 2012 by Yeoldetool 3 Quote Link to post Share on other sites
