If you check his instagram post it shows the difference between it and black hills mk262 |

It was good. Sub MOA. SD in the single digits. Averages about 100 fps more than IMI 77gr

My understanding is about a 10% shorter barrel life. I couldn't care less about this. The cases themselves weigh 1/3 less than brass so your ammo load is lighter.

Do we have any thoughts on the case? Material (steel), two piece design, etc.
I'll put my hand up and say I know nothing about the merits or drawbacks outside of the likely increased wear on the extractor/bolt/barrel. Performance and cost look nice |

Came across this YT video.
The young man runs 5 shot tests through several barrels from 12" to 20" while running AAC 77 as a side by side comparison. He shares his LR velocity stats and his 100 yard targets. I have never seen this guy before, but for what it is worth, keep or pitch. https://www.youtube.com/watch?v=ez61owRZIO8 It's not my thing, so I have no way to estimate pressure. We all know that extra velocity doesn't come for free, but I don't have a model of the steel case to run a pressure estimate so YMMV. Happy New Year! |

Performance and cost look nice Only real concern is increased bolt thrust, as there's less extraction friction compared to brass. This may effect FA rate of fire as well (I recall Shell Shock saw MP5's firing a good bit higher RPM with their 9mm.) FN is using these Shell Shock cases in its .264 LICC rifle design. Its using a Triangular bolt, possibly the better handle the higher pressure / bolt thrust. Otherwise these Shell Shock cases seem to be a better mousetrap then brass. As cheap / cheaper, very strong, lighter then brass, can be picked up with a magnet for reloaders. |

However they use steel bases vs aluminum used in 9mm, so may not be able to become cheaper then brass. Reloading the 9mm Shell Shock cases requires their proprietary dies and even with their carbide sizing die lubrication is still needed and that’s with straight walled pistol cases. The neck tension issues with these cases can cause poor seating concentricity.  The Shell Shock 9mm cases have been out for years, yet they’re still not in popular usage outside of a very small niche of 9mm Major competitors that are loading rounds to way beyond the SAAMI safety spec for 9mm +P ammunition. That’s what’s known as a clue. If you want to use these cases, knock yourself out, but don’t pretend that these cases are a “better mousetrap” than quality brass cases for reloaders. Have you even done any reloading with these cases? ….. |

I will be giving a small range report when I get my ammo and have time to chrono and shoot it. I placed the order, and the money is out of my account but I have yet to receive an order email, maybe I will have to call them  Edit: Looks like it got delivered yesterday. Had it shipped to my parents house but they never told me it got delivered. I might be able to get to the range this weekend to do some chrono/accuracy data. |

2625 with Mk262 11.5" 2624 with NAS3 2476 with Mk262 2600+ fps from an SBR length barrel...that bullet is humming along. I wonder what these cases do to bolts/extractors  |

Supposedly these cases are easier on extractors and internals than brass.

I shot them an email
Me "How much faster can we expect the barrel life to reduce using the Nas3 262's since they are pushing much higher than normal pressures?" John "The pressures aren't as high as most people.think. Most of the velocity gains are because of the additional internal volume that the case has. Allows us to get a higher charge rate without cranking up pressures to the extreme. Far as barrel life goes for say a stainless match barrel. We didn't see that much difference in life. Typically we change out our Douglas barrels at the 4k mark. But thats because we are using them for gathering test data. And we we able to hit that mark with 262Alpha. However every barrel is different. We are currently running a 18inch Douglas with nothing but 262Alpha and we just hit the 3k mark. So more to follow on that. We are going to shoot it till we see a decline in accuracy Hope this answers your questions. In ending I'd say it's a pay to play kinda deal. The performance gain is worth it to me! Especially at range. Now I would choose to use it more so for maximizing longer ranges. Save the brass stuff for more conventional shorter ranges/training etc Thanks, John" Me "Thanks for the quick reply! Any issues with wylde chambers? I'm looking at feeding these down a chrome lined criterion 1/8 wyde" John "No not at all! You'll be just fine. I would encourage you to try a stainless barrel at some point to extract as much accuracy potential as possible. However I will say I've seem the criterion barrel produce very respectable numbers for a chrome lines barrel. Thanks John" |
