300/.221 from .223

[strobes]

I was experimenting with .223 brass and all cases are caved as you can see on the picture. All was lubed well inside and out. And this are Redding dies that work well with .221 fireball. Any ideas what I'm missing?

I did that once with a .204 case and it looked good, no problems.

What expander did you use? I may have started with a .22, then used a .270 then .308.

Classic hydraulic dents.**** To much lube on the outside of the case******
Clean the die and start over with less lube. Ask me how I know

As the man said ... classic hydraulic dents. Too much lube.

I thought more is better when it's tight

Thanks
