I've played with this on a few rifles over the years. It can make a change in accuracy, but not always. Guess it depends on the rifle. I have to wonder though, on a short stroker and then it works after moving the cylinder forward, did anyone check for gas hole alignment first? Also have read, but never attempted to verify, that a worn muzzle can cause short stroking if the gas system parts are marginal to start with. I would think the bore would have to be shotgun smooth before losing enough gas to effect operation, but ya never know.....
I'm partial to the adjustable gas screw myself. Got them on my two shooters and once dialed in for the ammo being used the gun just "feels" better. The ones I have I got from Roland Beaver but since I got those there are now other folks selling them too. Right now they are set for HXP ammo as thats what I mostly shoot for basic range practice. I have used some 180gr soft points and can get the same "soft" feel with the adjustable screws. No need to beat up the guns anymore.
Gus taught me that as long as the entire port is inside the Gas-Cylinder window operation is uneffected. I've done that to get the correct standoff with the rear of the Cylinder vs. the front handguard ferrule and, by and large, this is true. Now that I think about it, these rifles ran good with whatever I stuck in them to shoot, even some old, slowboat LC I had. Accuracy off a bench was always pertty close at that point, 2-3" at 100. Maybe there's something to that Tim.
