I did a quick inventory on some of my supplies and decided that no, I did not need (or want) to buy any more 223/556 bullets. My primers are in 'ok' shape, but I could use more large rifle primers....once I get the reloading dies, and maybe some different powder, and bullets, yep those would be useful.
I am not in any rush right now for the new hardware unless I find a nice spot to plink with 308 Win.
