You might want to do more research on one shot stopping data and the proven way to attain that.
Good choice in ammo. I also use gold dot but in 9mm.
There is lots of information compiled by FBI and a doctor out of Chicago that sheds a lot of light on what's the best pistol round to neutralize a threat.
If you truly study effective handgun use you know that the "one shot stop" is pretty much a fable. Here is the conclusion to the 1989 handgun study performed by the FBI.
CONCLUSIONS
Physiologically, no caliber or bullet is certain to incapacitate any individual unless the brain is hit.
Psychologically, some individuals can be incapacitated by minor or small caliber wounds. Those
individuals who are stimulated by fear, adrenaline, drugs, alcohol, and/or sheer will and survival
determination may not be incapacitated even if mortally wounded.
The will to survive and to fight despite horrific damage to the body is commonplace on the battlefield,
and on the street. Barring a hit to the brain, the only way to force incapacitation is to cause sufficient
blood loss that the subject can no longer function, and that takes time. Even if the heart is instantly
destroyed, there is sufficient oxygen in the brain to support full and complete voluntary action for 10-15
seconds.
Kinetic energy does not wound. Temporary cavity does not wound. The much discussed "shock" of
bullet impact is a fable and "knock down" power is a myth. The critical element is penetration. The
bullet must pass through the large, blood bearing organs and be of sufficient diameter to promote rapid
bleeding. Penetration less than 12 inches is too little, and, in the words of two of the participants in the
1987 Wound Ballistics Workshop, "too little penetration will get you killed." Given desirable and
reliable penetration, the only way to increase bullet effectiveness is to increase the severity of the
wound by increasing the size of hole made by the bullet. Any bullet which will not penetrate through
vital organs from less than optimal angles is not acceptable. Of those that will penetrate, the edge is
always with the bigger bullet.
As I put from the ballistic tests shown the R.I.P. ammo would cause many small wound channels and one large one. Instead of getting one chance to nick or hit vital arteries or veins you get nine chances (the main body and the eight petals). This is in concept, in reality I can agree that this specific ammo using this specific idea won't work nearly as well as say Speer Gold Dots which have a long history or reliability in expansion, function, and penetration.
