I recently purchased some Hornady Match 168gr BTHP For my .308 needs. I'm running a hornady progressive press with lee dies. When I was seating the bullets I noticed that there were a couple of circular rings on the shell plate. They were shavings from the 168gr bullets. It appears that on some of the bullets were being shaved by the brass. Just enough to expose a different colour under the copper jacket. I've got pics to post but it was hard to get a pix of.

The brass I used I bought from a fellow CGN. He Cleaned, resized, and trimmed the brass, so I did none of the case prep on the brass.

So is the brass not sized properly? I've got about 500 pieces of it. Should I full length resize everything or just neck size the brass?

Second thing is, can I shoot these bullets and not cause issues to my barrel, part of the copper jacket is scratched so will this scratch my barrel?

I've got a norc m14 as well as a brand new marlin XS7 in .308. I'm worried about shooting these bullets from my new gun.

Also if this will cause a problem should I pull all the rounds?

Help is appreciated

here are the pics of a pulled bullet that I noticed was scratched.

The brass may need to be chamfered.

Those bullets will NOT harm your barrel.

I doubt even they will affect accuracy, there is absolutely no harm in trying them before you get TOO excited....;)
 
JoeNWT is correct, brass just needs to be chamfered a bit. He gives good advice, don't even worry about it, go ahead and shoot. I doubt you'd be able to measure any increase in group size, if any, from shooting those.
 
"...will this scratch my barrel?..." Copper will never scratch steel. Even mild steel is much harder than copper.
"...my .308 needs..." Target shooting only. Match bullets are not made for hunting anything. Mind you, a varmint like a coyote, won't notice or care. Just don't use 'em for any larger game.
"...Should I full length resize everything or..." The M305 requires it every time. You can neck size only for the Marlin after they've been fired out of it. Neck sizing is ok for a bolt action, but you must use the same cases that were fired out of it.
If you're planning on using the same brass in both rifles, you must FL resize when loading for one or the other. Not a big deal.
