Unknown suppressors OG testing

Please explain what you mean by “the 6.5 PRC is the upper limit of what the OG is really made for”.

So despite being a 30 cal can, it wasn’t really made for 7mm or 30 cal applications? Would reccomend something else then if someone was looking for a 7mm or 30 cal can then?

Also, now I’m really confused why the OG 6.5 needed to come out so quickly if the OG was ‘really made for’ the same thing. Educate me, not trying to be a dick but sincerely curious what you mean by comment above.

I think this comment speaks more to the fact the 6.5 PRC is a magnum and has less to do with bore diameter.

My understanding is that the OG was designed for non-magnums. So using with a 7-08 or 308 would be just fine and what it was designed for, whereas 7mm Mag or 300 Win Mag would be above the upper limit.

From the very beginning it was stated repeatedly that the OG was optimized for 30cal and below, and standard cartridges of 50’ish grains of powder and below. That while it will be below 140 dBA SE with most common magnum cartridges and barrel lengths, and safe to use with them- it was not optimized for magnums. If your primary use is magnum cartridges, unless added OAL is a primary concern, the OG is probably not what you want.
If you primarily use standard cartridges with only occasional use on magnums, it certainly is safe to use on them, and will be under 140 dBA SE. The 6UM and 6.5 PRC is about the upper limit of what I would use the OG on as a primary can.

Why and how of the OG65 has been explained to you multiple times.
 
Ok thanks. And what is the upper limit of the OG 6.5 for primary use applications? The same the OG as in 6UM and 6.5 PRC as well?

No. So far if it’ll fit through the bore, it suppresses well. 20” 7PRC is 132-133 dBA SE- that’s the same or better on average than lots of 7” cans.
 
Ok got it, the upper limit of the OG for primary use applications is 6UM/6.5 PRC while the upper limit of the OG 6.5 for primary use applications is 7 PRC.

UM wasn’t kidding around when they said the OG 6.5 was “way better”. I want one..

For probably the 5th time- the OG65 is not “way better” than the OG- they are different cans. They look the same, have definite cross over use, but they are DIFFERENT cans. It’s not “way better” without being specific in its use. That was ignorant of whoever said it.

The OG65 is better at suppressing 6.5mm and below (and potentially 7mm with the user accepting the possible risk) than the OG. It will also be not as durable overall- though more than durable enough for the use case. It isn’t “way better” with 308 or any other 30cal, or if you won’t accept the risk- with 277 or 7mm bullets. The OG will also be better long term on an AR in heavy use.

If US is looking to market beyond Rokslide members it would be wise to state this stuff on the product page rather than requiring anyone who buys a US product to find a forum they may not know about, then wade through 2-5 threads worth of posts and bickering to decipher product goals. US's page says the OG is "30 caliber" with no mention of powder quantities.

Amen.
 
Ear ringing topic. I have tinnitus and my ears always ring to some degree, loud noises increase it for a while. An AB raptor 8 with 3” reflex increases my ringing, so do other things that are <140db. Ear ringing alone isn’t a good indicator.
I have it too, and a couple shots coyote hunting open country out of my 21" 6.5 PRC with my Nomad Ti doesn't ring them, so that's now my standard.

100% agree.

I've been hundreds of yards downrange and had my ears ring just with the supersonic crack of some of the bullets passing overhead.

I've also had my ears ring from a bullwhip cracking.

Whether or not your ears ring with a suppressor is not a good threshold for its loudness. I suspect even bullet shape would have an impact on how loud your ears ring.
 
I have the OG, now have an Airlock en route. All my prior experience has been with large/heavy suppressors and while wearing earpro.

So far, my experience with suppressors & hunting leads me to say “I’ll never shoot that without hearing protection, it’s just too loud”. Maybe all the short/light cans are that way? Heck I don’t know if even the large/heavy ones are.

At any rate, I’ll have two in the same market echelon and will shoot them next to each other. I’ll get bystanders to weigh in as well. I’ve asked UM to swap for the OG 6.5 but stated in the same message that they owe me nothing, up to them we’ll see. I feel that would be a more fair comparison but admittedly I’m not likely to cough up the money for a third can.

I’m beginning to have my doubts about what electronic equipment measures versus what humans hear, and am now putting more weight on anecdotal comparisons with multiple onlookers sharing their thoughts. Not that testing equipment is in any way bad…just that actual head-to-head comparisons by real people carries more weight with me. Especially if they have their backs turned, which we’ll do.

It’s hunting season and the Airlock won’t be in hand until mid-October, but I’ll post the test & comments here.
 
I have the OG currently on my 16.5” 223 tikka. About 100 rounds through it so far but I am really liking it on the RSS. Compared to the ab-a10, banish 30, and banish backcountry head to head, myself and shooting buddies preferred the OG. (I don’t like the banish cans but wanted to include for further references). I have an OG 6.5 on order for my 6.5 PRC. I am glad the OG seems indestructible as it will go on a AR in the next year or two as I shuffle cans over the few years as I improve the stable and sell a few in 2026 with the stamp going to zero. The next can (and hopefully my last for a few years as I try to keep telling myself that) is down to: the reaper with attachment, airlock, another OG 6.5, or OG magnum. Looking forward to more testing and feedback from the RS community!

In terms of minimizing the risk of hearing loss, this is true of any suppressor. Even the very best suppressor only takes it down to the point where a few shots an hour is “safe.” You still need to avoid prolonged unprotected exposure to gunfire.

I trust in the general guidance of the OSHA 140 decibel standard as providing some safety margin, but when it comes down to it, for hunting purposes, my thought process is mostly that firing one or two shots suppressed to 133 or 127 or whatever with no plugs or headphones is better than firing one or two shots without a suppressor at 160 and with no plugs or headphones.

Oh for sure, I’m assuming if anyone has followed these threads then it’s known that south of 140 db is safe for limited exposure and that the lower the rating the longer the exposure can be; also that prolonged exposure to any suppressed gunfire is unsafe. My point is that as a new-to-hunting-suppressors guy…I’m wondering just how ‘comfortable’ the actual shot can be. And I’m sure many guys out there are as well.

So my post is to pose that question then follow up with some head to head tests and see how comfortable it can be. The lion’s share of testing will be with earpro, then the bystanders standing a far enough distance might want to go open-eared to hear more of a difference, and finally I might just pop off a few without mine on to see. And that goes with a “don’t do this at home” warning. I’ve heard all the “that’s stupid” comments, appreciate everyone’s concern, don’t care to hear more. It’s not like I’m cutting my fingers off to test knife efficacy. Although…

But I’m sure a ton of guys who are like me are wondering…”is it worth it?”. I mean if at the end of the day it’s still loud, adds weight to the end of your rifle, adds length, and costs over a grand…then is the only real tangible benefit that animals react less? Obviously any level of suppression is a benefit, but to those people who haven’t embarked down the suppressor road it might be pretty useful to hear from someone on that very subject before they spring for it. Might save some guys money, might make some guys all for it, but at the very least it’ll help set proper expectations.

No offense to all the WKRs on here but you guys are well-versed. To the new guys & lurkers, there’s not really a basis for comparison without experience. My only aim is to help shed some light for those guys.

I set up a rifle for a buddy last weekend and was forced to shoot with a radial brake he wanted left on, and it was a stark reminder of how valuable suppressors really are. I purchased another one last week and my wife's opinion changed from "do you really need another one?" to "yeah you should get one for each" after the weekend.

From my limited experience, it is still worth it. The few suppressed shots I fired without hearing protection, particularly when shooting at groundhogs on my farm (before the reeducation of Q Sertorius), were very pleasant. This was with the Scythe on the 18” 6.5mm Grendel. From my experience on the range, I think it is safe to say that on a short or long action cartridge with a barrel 20” or longer, even the short suppressors will be pleasant for hunting.

I’m on board with that, it echos sentiments I’ve read all over the interwebs. My test will be a 16” barreled 6mm Creed, so pushing that boundary a bit further.

Ha! Don’t get me started on brakes, they’re atrocious. I got into them last year, promptly gave them up. Even with I got “used to it” I’d still have a headache for the rest of the day after a long range session.
