    Unknown suppressors OG testing

    That'll be a huge contribution to this thread! Should help educate with the frequency content. Will you do bare muzzle compared to OG? Bare muzzle might exceed max amplitude and distortion limits of the 4133 though, but you could work around it with setup or a different mic. You probably...

    Unknown suppressors OG testing

    That's good to keep in mind if cellphone recordings are used. I'm scheduled to visit a dedicated lab with anechoic chamber and analyzers, just for consumer products like phones. Should be interesting but it's hard to keep track of the extent that sound is manipulated by each phone processor...

    Unknown suppressors OG testing

    Cellphone recordings are not ideal, but not totally worthless either. The manufacturer of your cellphone should have selected a mic with frequency response that matches the human ear. In other words, when you speak into your phone, it would be best for the device to capture your voice in the...

    Unknown suppressors OG testing

    Randy, Chuck shoot looks like a hoot. Get any sage rats over there? I'm convinced the chucks are smarter than the sage rats! Regarding the cellphone apps, there are two issues using them for gunfire: 1. One is the frequency response of the internal mic and/or accessory mics. Think about old...

    Top 5 Food bars while backpacking

    Bobo's are on sale at Costco so I bought some. I was skeptical but they are better than expected! I had incorrectly assumed they were like Crustables. Thanks Robinhood21!

    Diagnosing Horizontal Variation

    I'd check parallax. Horizontal screams shooter to me in general, as you guys have already pointed, but I'd rule out parallax first.

    Does any Other Brands make / sell Scope Rings with Composite Inserts similar to Burris Signature Rings for 1 inch High Mount?

    To help with alignment? No, not that I am aware of. Just Burris. But you can buy generic reducers, like 30mm to 1" or 34mm to 30mm, if you just want an insert. There are even some on Amazon, along with regular online stores. Or, the SWFA mounts and rings, as mentioned by LWA earlier. Badger...

    Unknown suppressors OG testing

    PS - I have discussed doing tests at the shooter's ear with a couple dealers over the years, but in the end neither party is super motivated. It may sound strange, since I have the equipment and basic knowledge to run the tests, but I am in agreement with some of what has been posted above -...

    Unknown suppressors OG testing

    J, That's a good question, regarding the meter used, mic selected, and settings. Without knowing the details of the equipment, we'd just be guessing. However, appropriate mics are expensive and sometimes called a "pressure mic". They are not typically included with generic SLM (sound level...

    Unknown suppressors OG testing

    I get it. I really do. Testing shit ain't for everyone. Or reporting it. It's a big job. Actually two big jobs. Or three jobs, if post processing is needed. But if you post numbers, especially against competitors' product, this just goes with the territory. There'll be questions - sorry!

    Unknown suppressors OG testing

    Good job, getting some measurements! I do have some setup questions though, as the true peak might be underestimated by the settings. Or the test setup could make the measurements worse. Sampling rate and pk rise time? What mic? Precision Class? Calibrate before and after, by any chance? Did...

    Drop Test Pass/Fail

    I understand your frustration, but I think you are highlighting aspects that are outside the scope of what Formi has laid out. Large sample sizes are obviously not realistic for this program, and if you go back and read some of Formi's posts he's been careful to call these scope "evals" and not...

    Drop Test Pass/Fail

    Good point, but forum parrots are good for clicks and web traffic. Especially when they fly off to other forums. And who doesn't want to be part of a clique? 🤪

    Scope Zero Check Thread

    I've seen it and dealt with it personally, but if you want to question it, you should start a new thread.

    Scope Zero Check Thread

    Wrong - the tiny little base screws have sufficient clamping force that the rail deforms to match the receiver, and obviously not the other way around. That's why it's easy to miss.

    Swarovski vs Kowa - The focusing system

    Lack of sharp focus at max zoom is an indicator of optical aberrations. As a rule of thumb, try 1x per 1mm of objective diameter. Minimum. So a 60mm should have good sharp focus at 60x with more and more detail as you approach the max. If it doesn't, then I would walk away but it would help...

    Scope Zero Check Thread

    This thread isn't the best format to judge the merits of formi's pre-flight checklist. It wasn't layed out for it, and that wasn't even the intention, but I can definitely understand why you are questioning some of the results against the claims. As he stated, you don't know if all the steps...

    What rifle is missing stock options?

    +1 I would also add Kimber 84L, with the option to utilize the OEM mag supplied with the Hunter or other DM.

    Swarovski vs Kowa - The focusing system

    If the Swaro snapped into focus faster, it is due to better optical correction. And a well implemented focuser mechanism, as you can have a well corrected scope but poor focuser (not smooth, jumpy, etc.). You can also have a poor or mediocre scope, in terms of correction, yet some people will...
