Since I am new to the rifle scene, got a question(dont want to get the wrong ammo). I'm planning to buy a case from cheaper than dirt. They have this Winchester .223 but i dont know if there is a difference between the two since they are both .223. If there is not a difference, they why the price diff.
1. Winchester USA .223--3.99
2. Winchester USA .223(5.56)- 3.69
Can anybody help me out, tried calling but could not get through to customer service. Correct me if I'm wrong but isnt 5.56 the same as .223

M855 should be fine with the 1:9 Mini twist - unless the weather is exceptionally cold or you are in a deep cave, both conditions raising the air pressure - and the round dimensions must be the same. It is only the even longer M856 61gr long range tracer that needs 1:7 twist under normal conditions.
