Ok- I know that the new heavier 75/77gr.'s are performing farther out than the 55/62gr. variants in M4's w/ 1/7 twists. But that would get expensive to shoot all the time, and also might not always be available. How would the 55 and 62 gr's do in a 1/7" twist 14.5". Would the combo degrade their performance?
Is it a win win situation or win lose?

Both work fine in 1/7 (hey the military use their M855 in 1:7 exclusively). There is a small change in the point of impact if you don't rezero. Some people say the 55gr isn't as accurate in a 1:7 as it is in 1:9 or 1:12. In my experiance that is highly dependant on the load used & rifle in question (not to mention the operator). In all cases it was accurate enough for any defensive use.

All I can say is that Ammo Oracle states you can spin a bullet too fast for it's weight and throw off it's accuracy. I would think 55 grain is a little light for 1/7

1:7 works fine with M193 IT is not over spun.
