Winchester 308 brass problem

rottieman33 · September 27, 2009, 08:29 PM

Can some one tell me the cause of this new to reloading about 25 out 100 cases the shoulder was dented all the way around after running threw the sizer die.

Lube on shoulders and/or lube buildup in die. Tahe the die apart and clean it. Also, don't apply lube to case shoulder area.

on a positive note.... it has no effect on the performance of reloading it.... and... once you shoot it.... it wont still be there.

My dies I clead saturday and no lube on the shoulder I make sure of that didn't know if the winchester brass is crappy. So they are still safe to shoot

+1 on the excess lube. I have seen this before in my own reloading using a lube pad. The lube will accumulate at the neck area and cause these dents. Use just enough lube to allow the cases to size without excess force, and roll them so you coat only the body, never the neck area.

As an alternate, use spray lube and you'll never see this problem.

Safe to shoot but it will wear the neck, resulting in overly worked brass in this critical area, causing a shorter reloading life.

Yep 'just to much lube used , and check your die and make sure the tinny little vent hole is not plugged. if there is no where for the air to go it will dent the case. right where yours is. Been there .

I have been there when I reloaded my .204 - same problem. It was the vent hole. But to much lube does it as well. keep the lube off the neck . only lube the side of the case and a brush inside the neck with a little lube rolled onto the brush. Everyone messes up some times.

I looked for a vent hole couldn't find one. may be i got bad rcbs dies cause its been a bitch to resize the brass.

Vent hole probably under locking ring

Just because it took nearly a year for me to find out... if you use a progressive press, buy a lube die. Speeds thing up greatly. Heck, might work without the progressive press with a little yankee engineering.

Try Imperial Die Wax. Best stuff since sliced bread, a little goes a loooooong way.
