There seems to be very little wear in any of them. Certainly not anything that would impede effectiveness, even on the shorty barrels.
Suppressors are made well. |

Have there been any 17-4 blast baffles in this thread? I need to look through it again I would expect the long bearing inside bore diameter of the very thick yhm blast baffle to focus gas (the gas not flowing through the huge peripheral holes) in a laminar tight pencil like cone like a blasting nozzle and probably the wear you see on the more forward baffles is the result of that. It may also be that the cones are very sharp and their geometry is promoting wear from that. |

  Full-size Turbo now around 8k or so rounds, almost all on 10 and 11" barrels and all through YHM brakes. I don't do mag dumps but this can sees hard use and has now been through three carbine courses, several rain storms, and countless bumps/knocks against barricades to include a spill off a moving ATV. A few things I found interesting to my non-engineer eyes. - Blast baffle looks fine to me. - It's tough to get a good look at the baffles but I think I can see some of what @STJ exhibited; more wear on the second baffle. Mine is not as exaggerated and it's more accurate to say that the first baffle looks pristine. - There's an obvious concentration of lead/carbon where the first port of the brake is. Recent exposure to heavy rain while shooting introduced specks of surface rust. - The can is steadily picking up weight but performance is otherwise still excellent. |

The YHM brakes seem to deposit carbon on the side walls, which makes sense.
While I don't have the rounds count on some of the Turbo cans posted, I can still see the seam between the blast baffle and tube. |

That could be a good candidate for weighing, soaking a couple of days in CLR with at least one changout, drying and re-weighing, and taking before and after pics. Not sure if YHM recommends CLR so that would be something worth checking first. |

I think a lot of people miss that the whole baffle system needs to be durable, and one very durable baffle will always make the stack look durable, but doesn't always guaranty a superior silencer. Sales guys went to a local swat demo shoot today, and at the shoot, they inquired about M4SD II's we sold them in 2016, and the Swat team said their cans have 10,000 rounds on them at this point and only minimal wear and no issues. |

No pics, but I’m already glad I went with the DA Keymo brake for my 7.5” 5.56. Just a few slow mags through my Nomad, and you can already see cratering in the brake. I know this host is on the “harder” end of the spectrum as far as can wear. I’m also glad to hear GA’s take on 17-4 as it regards to baffle design. I don’t baby my stuff, but I like to set my equipment up for success if I can help it.

30SDK 50,000 documented rounds fired mostly .556mm on 12.5" and shorter barrels at high rates of fire mostly at carbine courses by an industry instructor. Silencer sound tested 2DB louder than new when compared to a new 30SDK silencer of the same baffle revision. Only the first baffle has eroded through to the secondary slot cut near the aperture. This pre mod-4 unit is being re-baffled for the customer under an elective service, but is currently serviceable. Another good thing to remember is baffle proximity plays a role in wear, and the 30SDK stack is squashed into less space. The blast baffle is closer (more wear prone) than other gate lock models by maybe .800” if memory serves me correctly. That second baffle that is intact is closer to where primary baffles are in the other series cans. The baffles are also all the same thickness so there are no weaker parts up front.
This was a cool can to see, it is the highest documented round count Griffin can I have ever seen. That's $25,000 worth of ammunition through a can streeting for $851 MAP. Second place goes to a Optimus micro that spent its life on a machine gun rental range (no known round count on that unit but the first baffle was also erroded through at the aperture a little worse than this one). That one was rebuilt also- it took us like 2 hours to get the baffles out, which we replaced. The micro also soldiers on.    On Facebook someone thought this can had baffle strikes. All the baffles are round bored, no evidence of any strikes, that one piece of the blast baffle is worn off, but this is basically the closest proximity blast baffle in the lineup, and closer proximity will make wear worse. The second baffle is intact. |

You can kind of see that the abrasives kept the baffles from packing up. There is nothing particularly noteworthy in there as far as fouling. If there are no coaxial chambers the cans probably won't gain considerable weight. Ours don't. The YHM looks pretty much clear.

After you posted the 50k suppressor I’ve been looking at getting a griffin as a rental can A demo can is an effective sales and marketing tool, we have a demo program for dealers, you can get those at a discount on a couple cans a year as demos. For 200-300 rounds at a crack on a short barrel, our sdqd stuff is pretty solid for heavy use like that. They cool faster with the tube fluting and they are a bit heavier for durability. The first test for the original smooth tube 30sd was 500 rds of 16” barrel 308 in under two hours. I can’t remember the exact time it might have been 90 minutes, we had a temp gun and kept it at 1200F for the 500rds. |

Quote HistoryOriginally Posted By SMFdarkangel: Does the Sierra 5 have MIM baffles? Those look a lot like ejector marks. They are probably cast. I think most stellite baffles are cast. If so those would be the ejector marks of the lost wax part that was ceramic slurried and baked as the sacrificial mold for the poured stellite parts on the tree comprising the casting for that pour. The properties of cast materials are unique to that process, and the properties of those processes are almost tradecraft to the casting industry. They have special publications they pay a lot of money for that are not generally public knowledge that discuss the formulas and properties of the various material/process parameter pairings. I had one bad experience with cast properties using 625 inconel, where I learned that 625 derives 50% of its strength from cold reduction (rolling bar or sheet), and the cast process for that material yields a high nickel alloy part about as strong as rolled 316L stainless steel. In other words stamped 625 is totally superior to cast 625. Obviously this is a different material application so I’m only illustrating the complexities of casting that can potentially complicate that. |
