Dented brass

Are they at the case mouth or in the case side's. For case mouth dents, get a taperd punch and GENTELY tap the punch into the case to get most of the dent out(leave a little bit of the dent so you dont stretch the brass),the sizeing die will return it to proper spec. For sidewall dents, lube and full length resize slowly. Next fireing re remove any(normaly) trace of dent. I have recovered caseing that were near crushed flat and still got 4-5 reloads before they split.

As the pressure in the case rises, the caseing will swell to the chamber wall thereby returning to "factory" spec all within a few milionths of a second. If you are running a compressed charge, you will infact have a slightly reduced charge as the pressure rises.

Get a new rifle.
I personally don't like the mini-14, the one I had was terrible. I sold it after a couple months of 6-8 inch groups at 100yds.
They are very hard on brass because they are extremely overgassed. If you really like the rifle then I would invest in an adjustable gas block for it. Mine cycled so hard it would throw brass 30 feet and made the same dents in the side that you describe. On the positive side though, because they are overgassed they cycle anything and are reliable. I always felt like it was eventually going to hammer itself to death.
Aside from reducing the gas system pressure to slow down the bolt velocity there won't be much for options. I tried a recoil buffer and all it did was prevent the bolt from locking back reliably.
