Gas System?
When do I need to learn about the gas system?
S&W MP. 16" barrel.
So let's say I start loading for it. (I've already started, I just haven't done any serious testing yet.)
I take the recipe straight out of the manual, start at the bottom. Now, I expect some of the lower loads to fail to cycle the action. Just like a 1911.
Here's my question: if I find a load somewhere in the middle that runs the gun, what, if anything, do I need to know about my gas system? Is my gas system adjustable? Why (and when) would I worry about the gas system on the gun?
Can't I just find the lowest load that runs the gun and be happy? What is there to be gained by adjusting the gas system? When would I do so, and why?
Thanks, gang!
