Getting a llittle powder residue on cases

[patchman12]

Hoping for a little help here. Savage Mod 12, 6BR. New brass, loaded mild. recently noticed some black colored powder burn on bolt face (lugs) and on brass near base on the sides. Any idea what I'm doing wrong? I felt very good about my head space setting, but I'm confused now. Thanks! :) :)

:D 10 - 4, back door. Many thanks...I'll do this at same time as a ladder test to "tune" this sweet rig!

I have a unmodded m 11 .223 and i am having the same issue with factory ammo (fiochhi 50gr vmax) What would cause this condition?

Does it only do it with that one load? Has the gun had any problems in the past or is it new? How does the bolt feel when chambering/extracting?

[jmo82]

Thats more/less the only load I ever shoot in that gun. The few times I ever shot anything else I didn't pay any attention to the cases. The gun seems to chambers and extract fine. I just noticed this the last few times at the range, but it may have always done this. It doesn't do it to every case, just every third or fourth round.

don't get to excited, a little is not a bad thing.

When you get right down to the nitty gritty it can only be the fault of one thing. The ammo.
If that Fiocchi is shooting bugholes for ya you might learn to accept it. I know it would bug the he!! out of me simply because it should'nt happen but.........

You may want to make sure its blowby leaking around the case and not simply leaking around those Fiocchi primers.
I bought some Fiocchi primers about four years ago. I think I've used about ten so far

Blowby around the case is unsightly and indicitave of not enough pressure or severely hardened brass. Neither is very dangerous in a Savage action.
Leaking around the primer could eventually scar your bolt face. Still not very dangerous to the shooter in a Savage action.
We can thank the solid rear bolt on the Sav action for that.
