Better performance with under stabilized 75-77gr?

[williamN]

At home defense ranges <25yds, would a 75+gr round be more effective out of a 1:9 or even a 1:12 barrel than the 1:7?

No.
Then again, what is your definintion of "effective"?

damage, trauma, stopping the aggressor faster.

Edited to add that I wasn't asking about or expecting phenominal increase just wondering if there would be ANY increase however small.

It is possible that a projectile at higher yaw angle due to poor stabilization could create a more severe wound--however, the effect is not predictable or reliable. In addition, accuracy is substantially reduced. Most folks doing CQB desire accuracy, predictability, and reliability--poorly stabilized bullets offer NONE of those characteristics...

How (in)accurate would a 75gr bullet be at home defense ranges ( less than 25yds, any more than that and you will probably be looking at murder charges) out of a bore with a twist rate of 1:9 or 1:12? The only time I shot a 75gr in a 1:9 I was getting less than 1.5" @ 100yds. Even if my rifle was shooting 4X better than average that still means a 1.5 or less at HD ranges.

Depends on the rifle, load, etc...

I think William you are looking for a solution when there is no problem. The key of effective fire is location,location and location. Put your bullet where it needs to go and the rest is gravy.

Just a curiousity question. Not looking to try to make a bullet unstable.

I remembered reading of how the Mujahideen feared the unstable ( once it hit flesh due to design) Soviet 5.45 round from first hand experience. Just made me wonder.

Look at the assault rifle chart looks to me as if the 5.56 does better than the 5.45x39 does with out trying to destabilize it . https://www.m4carbine.net/showthread.php?t=19937
