Folks,



That Winchester Ranger 9mm 127gr. jhp +P+ load so many like to use as their carry load in 9mm is marked "for use in handguns only" on the box? Any insights into why that is so?



Thanks in advance,

Hello. I am not sure but perhaps this is there to preclude use in semiauto carbines having blowback actions?



Best.

I see. That would force the bolt back too quickly, develop too much chamber pressure, or some other unforeseen functioning problems, yes?



Thanks,

Mr. Camp, is +P & +P+ used much in the MP5?



Thanks,

I'm not Mr. Camp, but I believe so. Remember that stuff that's dangerous to shoot in handguns because of the high pressure?



Isn't the MP5 locked breach? I've never really messed with them enough to know.

Hello, Sockman. The MP5 had a delayed roller bolt that acts like a locked breech. I've shot +P handgun ammo through them, but as is the case with handguns, +P does accelerate wear such that the bolts have to have some of the smaller parts replaced sooner than if using standard pressure ammunition. We wound up using Federal 115-gr. JHP (standard pressure) as it grouped quite well and was travelling about the same as their +P+ version from a service sized handgun.



The +P+ handgun stuff might cause a straight blowback carbine action to open a bit sooner and possibly while the bullet was still in the barrel. This would accelerate wear on the gun very quickly and possibly cause a very unsupported case to rupture...and it may just be because the makers never tested it for other than handguns and are seeking to limit potential liability.



Best.

My agency was initially issuing Gold Dot in standard, +P and +P+ loads. We quickly discovered the +P+ loads in our issued MP5 were damaging the roller block according to our agency armorers. At that point the +P+ became a prohibited load.



Hope this is helpful to someone.
