I have been reloading other calibers for a while with no real difficulties. I finally ordered my WOA varmint upper so I figured I should get all the stuff to reload for .223. I got the RCBS small base 2 die set and got it all set up. I full length resized the brass that I had put through a friends upper while waiting for mine to come in and everything looked good. I made a dummy round to help set up the seater and it looked good. I checked in the Sierra reloading manual and cross checked in the Lee handbook and picked out a good starter load for 68-69gr hpbt match bullets. I have sierra 69gr. MK hpbt, nosler custom comp. 69gr. hpbt, and hornady 68gr. hpbt. The load I picked is 25.3gr of Varget and is well below max pressure but when I go to seat the bullets the RCBS seater die is pressing a ring into the bullets about an 8th inch behind the tip. Also the load is not listed as compressed but it deffinately is.

Anyone know whats going on here???
