blemished brass

[RidgeRebel]

My DPMS 308 leaves slight dings in the brass when they are ejected. So I have Hornady Match brass that are once fired and have slight dings in the middle of the case. I have resized and polished them to be loaded again but my question is how will the slight dings affect accuracy?

Re: blemished brass

Only in your mind,

since they have been rezised and will fit the chamber they will work great,

just one precaution, very sharp dings, edged dings are starting points for cracks in the brass,

however I have a feeling these dings you mention are more or less just beauty marks?

As long as the marks are dent and dings and not cuts or scratches, they should good to go.

Try putting a rubber "bumper" at the rear of your bolt access area. These have been made for years by rubber molding companies. I have had to re-attach a few of these. I usually use a "rubber to metal" cement. The last time I used "Liquid Nails".

Thanks guys
Thay are just slight dents from hitting the back of the bolt access area like Victor says I think. Victor where would I find such a moulding?

You can try Champion's Choice out of Nashville, TN or Brownell's. Most shops that have competitive AR parts should have them or something like it.

Little piece of inner tube rubber held on by 3M auto weatherstrip cement. The yellow stuff. JMHO

I just redesigned my AR bump to make it at right angle to ejection port with Devcon putty. It is hardening up right now.
Should eject brass towards 1:30 if I did it right. Will put a rubber bumper on it. It is door insulation kit available at Home Depot. Enough for maybe a hundred rifles.

I will probably go over outside of mold with J-B weld to toughen it up and darken it.

I did this on a previous rifle and brass looked like it came out of a bolt gun. No dents, dings, bent necks etc.

Re: blemished brass

I have successfully made them from a slice of truck tire tread and shaped on a belt sander and Dremel tool.

I'm not really sure if "foam" rubber will absorb the hit.
