i know iv pulled your leg a little over the hornet,but if your thinking of getting a 223 anyway,why dont you just get a 223 and some reloading kit...the reloading kit takes up very little space and you can run 223 with 32grain heads upto some quite heavy heads (im not sure how heavey )then you can tailor your 223 round to what and where your shooting.....iv got 22.lr which is handy,17hmr not sure how handy,223 will do pritty much everything i want..
