I am used to reloading 308 brass using my small base Redding dies. Most brass I have resized are from AR-308 and FNAR. It does take quite a bit of force to size them (small base).

My issue is reloading fired brass from a SCAR17. The shoulder gets a bit wrinkled (lube dents). I added less lube, but same result. I have not made adjustments to my dies. The 308s I have done before have all been perfect. Could my problem be from the brass being fired from a SCAR?

I had similar issues when I started loading for my L1A1.
Light lube works the best for me (Lyman dies), but I had to clean and degrease my dies first to get the excess buildup of lube out of them.

Since I've started using less lube, I've only seen slight wrinkles on brass I've fired 4-5 times.

Thanks. My lube dents are very minimal now, but not perfect.

Are you using any gages to tell you the difference between the fired case size and your 'sized' case size?

You might not have to size them down as much as you're doing.

Hydraulic dents are generally due to too much lube, but you don't want to stick a case in the die, either.

I would take the die apart & clean it.
Probably gunk built up in there. Doesn't take much.

Also check the vent hole in the die, could be blocked.
