In spite of using a RCBS small base die {or Lee, or Hornady full length size die} I'm having problems with my 223 reloads not going all the way into battery/bolt not going all the way home. I'm sizing everything I can get into the die. Forward assist gets all rounds into battery but unless fired round/s are hard to get out...requires a lot of pressure or a bump on the charge handle to remove. Not all rounds give problems. I'm using mostly LC brass. Have been loading for several years but I'm about stumped. Can't help but suspect that dies aren't bringing brass back to spec. ?
