No 158gr ammo in MP5 per the Heckler & Koch MP5 users manual.
158gr ammo is VERY hard on the gun, the bullet is too heavy and will destroy parts- the roller retainer is usually the first to go. Trust me.

Ok, so no 158gr.
Any trouble with aluminum or steel cases? I normally steer clear of those but just in case. |

I don't use aluminum cased ammo but, here's what HK had to say about steel cased ammunition:
"Cartridge case obturation, the greatest uncertainty factor in every automatic weapon, is reduced so much by the introduction and further development of the fluted chamber and has become uniform for all types of cartridge cases, including lacquered steel cases, that operation is reliable in every situation, even under the most adverse firing conditions. - Heckler & Koch, GmbH 1970" |

I have run 1000's of rounds of Fiocchi subsonic 158gr through my gun with no problems. I am guessing the 158 referenced here as a no-go is the IMI type.

That stuff is like 158 +P. Simply changing to 158 which comes with a reduced powder load in standard pressure loadings, I just don't see that being harder on the system. That being said, I have tested 147 and 158 from a pistol host and there really wasn't a noticeable difference to me. So once AAC gets their stuff together and sends me my triad adapter I intend to just shoot Speer 147 TMJ from my clone. Reason for this is no lead in the can or in any blowback. Can be had reasonably priced from SG. |

I put about 1500 rounds of Fiocchi 158gr through my mp5k-pdw with DLO trigger frame. It ran great. Jim Schatz posted on HK Pro that shooting ANY bullet over 147gr is not advised. I stopped using it in my K and it is now used only in my fullsize vector UZI and suppressed beretta 92fs. Maybe it will be fine, but I don't care to push my luck in my all German SP89 converted to mp5k-pdw with factory pdw Navy barrel. In a clone I would probably keep shooting it. |
