Cartridge Swipes

[Robin]

These are pretty mild, what I gathered from previous conversations on this subject. This load is for a .223 Wilde chambering that I am working up a load to hunt deer with. Yes, I know, I know, .223 is marginal for deer at best, but I am a very disciplined hunter and don't take shots unless they are well within the capabilities of myself and my equipment.
There is no data for the bullet, 65 gr. SSPBT, powder, CFE223 combo, I'm working with so I took data from the next weight up and the next weight down and started at the low end, slowly working my way up to where I am now.
I will be putting these loads through the chronograph later today, hopefully, and was thinking of upping the powder a touch.
I was wondering at what point does it become detrimental to the equipment when these swipes begin to show up and what is affected?

Those don't look concerning to me. Extraction and ejection in the ARs can be a little rough. Are there any weird marks on the sides of the cases?

There is data for 64 grain bullets using CFE223 here. They're using 26.0 grains.

I did not see any marks on the sides of the casings. Is there something I should be on the look out for?
Thank you for the Article Kev74, Lots of good information there!!!!!!

Swipes can be caused by the bolt too. If there are burrs or sharp edges on the bolt face (usually the ejector hole, occasionally the extractor slot) it will cause swipes with mild loads. Oversized chamfers on those can cause swipes too - not enough support and the brass deforms into the void.

I don't think swipes hurt the rifle until you start shaving the brass rather than just smearing it. Brass shaving obviously becomes a contamination issue.

I would assume they affect reloadability but it's entirely possible that forming corrects any headspacing issues that might be caused by the head deformation of the swipe. My 6.8 swiped everything, especially in the beginning. I haven't shot too many reloads out of it, but I haven't noticed any issues using swiped brass.

Thank you ManrisFrank. I'm using Lapua brass, first time through and will take note of this.
Love my 6.8!!!!!!

When the bolt doesn't cycle you have pressure.
