Just put a new wilson combat 22" supersniper barrel in my rifle. I had heard they are hammers. This one is not a hammer. Also has anyone seen marks like this on brass before? I have not.....

The marks are from the neck hitting the barrel extension locking lugs, usually I smooth them out before
installing the barrel.

As far as the barrel not being a hammer, cant be sure of anything but many times its the guy
swinging the golf club not the golf club itself.
 
I would probably agree with you about the guy and his club if it was just myself- but I had mama shoot it half the time and she can flat out shoot....
 
Yep got a .308 that leaves two identical lines on the necks just like those.
 
How bad is “not a hammer”? I had a Rainer ultramatch barrel do that to brass.
 
Someone come correct me if I'm wrong, but I had a problem with my brass like that, and was told to cut one coil at a time off the ejector spring, I ending up cutting 3 off and the problem went away. I believe the neck is hitting the barrel extension. Cutting a coil or 4 from the ejector spring will relieve the problem...at least it did for me.

IMO it is better to remove the sharp edges from the barrel extension than to reduce the ejection force.
 
Would agree that polishing feedramps in barrel extension should be done regardless. Ejector springs are cheap-have a couple on hand and reduce a coil at a time and see if this resolves your issue. Have done same on a handful of Grendels with excellent results.
That said, have two Wilson Combat Grendel barrels and after 80-100 rounds, they settle in and will shoot. Handloads or factory?

Okay, polish the feed ramps first and if that doesn't work, then remove a coil at a time from the spring. I've examined a few ejector springs from various BCGs, albeit all small frame ARs, but they varied in length. Trimming a few coils isn't going to hurt anything. Think the problem is too much ejection force.

Not the feed ramps, the locking lug sharp edges.

It isn't the feed ramps. If you chamber a round then pull back on the charge handle slowly you can see the case rub across the extension lugs at 2:00 those are the ones that should be rounded off.
Cutting off the coils of the ejector springs may lead to the rifle having ejection/stovepipe problems.

Agreed. I always polish feed ramps and lightly hit surrounding lugs inside extension, so generally don’t have issues. And have taken a very minimal approach to cutting coils from ejector springs, never more than about .030-.040 off OAL. Tends to eject brass around 3-4pm in a tight pile, but this is my experience and should be approached with a somewhat conservative view. Polishing feed ramps and blending to receiver without changing angles also a functional plus.
 
Typically, if it is the feed ramps... aren't there usually dual marks ?
None the less... I would polish the feed ramps and the 2 o'clock lug, in case it is scratching the ejecting case.

I would suggest trying some different ammo as well.

How many rounds through it so far ?
