So they're ok to continue reloading with dents that bad in the shoulder?
As Bob said - too much case lube being used. Clean the inside of your sizing die & use less on the cases.
They will be ok to load - as long as you're not running an extremely hot load. - If you have loaded these before with the same bullet, powder load, primer & seating depth and had no signs of pressure, you should have no problems.
If it's one or two should be fine so long as your not at the ragged maximum pressure the rifle can withhold.
As Bob suggests clean out the die to prevent any more.
Keep sizing lube lube off the case shoulder. The suggestions above are right. The cases will fireform out, but they don't look pretty and the problem can be avoided. ATB

This may be the appropriate time to bin your greasy lube and buy some Imperial Sizing wax - you wont get that problem again.
Or if you dont want the hassle of wiping each case over & applying it to the inside of the neck, you could use Hornady One Shot spray. Lube a tray of 50 in 5 seconds & it is an excellent lube.
