That's quite normal and the dings will come out when you size the brass in your sizing die. Also keep in mind that if you are trying to reload military brass you'll need to remove the primer pocket crimp to seat new primers. You can do that by either reaming the crimp out of the primer pocket with your reamer/chamfer tool or by swagging out the primer pocket. If you choose to ream it out just take your reamer that you use to debur brass and put it in the primer pocket and give it a few twists and then try to seat a primer gently if it won't go in don't force it just use the reamer and do a few more twists and keep doing that until you get the primer to seat like normal. Try to track how many twists it takes and then do the appropriate amount on the rest of the brass. Personally I use a swagger. Lee makes swaggers and another company I don't recall the name of but I have their set which is quite nice. The Lee swagger looks nice too but I've not got a set yet.
