JR... as many have pointed out the 223 is cheap and easily obtainable... BUT you asked about reloading so I'm gonna have to go with the 22-250... been associated with this round for near 30 years now and have no idea how many rounds I've reloaded for it... this has to be the most user friendly round out there when it comes to loading... I've been hard pressed to find a load that won't give atleast ¾" at 100 yards... and most going much smaller... years back when I was in Europe I had a fellow tell me the 22-250 was a pain to load for, hard to get good consistant accuracy... well rather than argue with him I took him to the loading room and proceeded to size and prime 5 cases... got out a can of Norma 203, dipped the cases full and shook the powder out of the neck... WARNING... DO NOT TRY THIS AT HOME... I KNEW THIS POWDER WOULD NOT OVERLOAD THIS CASE... seated the bullets, and handed them to this gent... we then proceeded to the range where he handed me the ammo... I stuck all 5 in a group under ½" at 110 yards... needless to say we had another convert that day... as I said user friendly... I've tried both of the loads mentioned above but with different primers and they both shot good... 223 is cheap but the 22-250 if you're going to reload is much more versatile... load it down for plinking, or turn it up a notch and make it sizzle...
