leave barrel at 20" for now..... supress if you can afford it,to reshorten late will cost less than $150 and you can t add length back on.
when you can shoot CONSISTANTLY into a 3" area you could shoot a deer at same range but the 223 is at its best (some might say ethically only good for) under 150 yards....I will stretch that to 200 in perfect conditions for deer of pigs...wallabies hares etc as far as can make a hit.
