XCR 556 denting brass? Lowest gas settings always works?

[rob350]

First time trying my brass catcher on the XCR today. Noticed approx 1/3 of the brass has a fair size bend/crease in the brass, rearward of the shoulder.

Although I don't reload, I try to save for the future. Figure this makes the brass garbage.

Not sure if related or not, I ran 6 different types of 556 and 223 out of her today, as always runs no problems on gas setting 1. Never need to go higher. Did not try all ammo on "S" but runs just fine on S as well. Unless its more for running different calibres, seems useless on 556/223, or a smaller setting could even be useful. (mine has the 1-4 setting + S, not the newest 1-7 or 9 or what ever it is)
I thought the idea was keep turning down until it stops working reliably, then go up one. Mine always works lol.

Hey,good that you have no issues.
I believe S is for use of a sound suppresser. ( I can't wait until they become legal )

1 always worked for me.

I had dents in my brass as well, I just reloaded them and continued on

No issues or worries, this is due to the fixed ejector. The right thing to do is run the gas setting as low as possible while still being reliable. S is for if you're running a suppressor that has back pressure and will reliable cycle on lower velocity rounds, in addition to being adjustable by calibers.

The good thing about being about being able to adjust gas is making things easier on the rifle / less wear, in addition to tuning to your ammo. It's not just about cycling, it'll change harmonics with different loads - different gas settings with specific ammo 'may' results in different accuracy. The newer gas blocks give you more adjustability and are low profile for going under competition length uppers.

This wont cause issues for reloading unless your gas is turned up really high and it's really trashing the brass. Should come out just fine in full length sizing.
