Moving to the next step in my home-brew AR-15. I am finding some differing information on the effect of barrel twists on .223 vs. the 5.56. Some are of the opinion that the slightly heaver ball on the 5.56 calls for a barrel twist of 1 to 7, while the .223 does well with a twist of 1 to 9. Some go the middle ground and recommend a 1 to 8 in order to split the difference. Granted the 5.56 can have higher chamber pressure than the .223 and that would have to be addressed but what have people experienced with the various barrel twists on the 5.56 vs the .223?
