Looks like to much lube possibly. I had some 223 cases do the same thing when I first started and it was from to much lube. Maybe use a little less and try cleaning your die out.

too much lube on the shoulders

 

[LHancock]

That is probably it. I was thinking not enough, so was generous with it. I'll clean up and try again. Thanks

A __TINY__ bit goes a long way !!!

 

[DizzyJ]

Yep. Looks like hydraulic denting from too much lube. It takes very little lube to properly cover a case.

But....
Too little and you'll find out real quick!

Thank you one and all. That was it. I spent 45 yrs in the auto industry and over lubrication was NEVER an issue. But I can see where hydrostatic lock can develop in that small area. This is the first of many problems I am sure to come across, and I will not hesitate to ask again. You guys & gals are the best.

Generally fluids do not compress - so yes, they can cause this. I made this mistake when I first started out too.

Maybe try a dry film lube like Hornady OneShot.

Been using Hornady OneShot for years. One can should last a long time, great stuff. A little goes a long ways.

Yeah,, over lubrication is NEVER an issue with 1911s either. If the oil isn't running down your arm you need more.

Generally? Name one that does!

I quit using one shot due to dented cases. A light smear of imperial sizing wax is ALL you need.

Only technically, mind you: Dot 5 silicone brake fluid.

A quick note about spray lubes. Most take a little while to set and will cause a case to stick if the lube is still wet.

RCBS makes a nice little case extractor for when ya stick a case in the sizing die.

As mentioned by most all of the other respondents, those are lube dents. If not using the case for a heavy charge, they can be fireformed back out.

"Technically", from say.... flexible brake hoses expanding under pressure.

I always use weasel words to cover my posterior because there are often some exceptional cases I am not aware of:

I usually do the same because I don't want to appear to be arrogant, which happens enough when using text instead of talking.
