This is going to ruffle feathers because it won't be three posts before I start being told how this is impossible, and results will be meaningless, etc... etc... When I push back the argument will become, "I've been doing this since before my grandfather was born... and yada yada". That will...

The Standard Range The test range is laid out like this diagram: The diagram is as I drew it into my notebook. The bench is on the left side of the diagram and the backstop is on the right side. The microphone is located at the top between the two triangles. It is placed on a concrete slab (a...

Question was something like, "What do you think of decibel meter X compared to decibel meter Y?" Second question was something like, "Why is your method different/better than using a decibel meter?" This is the long answer. You will need to understand what I did in THIS THREAD to follow the...

Here are three signatures from different setups at ~88 yards. The first is a shot from a Talon P tuned to shoot JSB Heavy (15.89, .20 cal) at 800 fps for about 22 foot pounds. The rifle is bare. The second is a shot from the same rifle with a "Standard" moderator with gyroid infil. This is a...

Just for giggles, today after I got back from a Squirrel hunt I decided to see what my Talon P sounded like at 100 yards. The gun is running a moderator design I call the "Krait". The moderator is 40mm x 127mm and is for all practical purposes an enlarged "Ember" which we have had so much...

New not used. I have three of these for sale. Carbon Fiber and PETG baffles with resin printed endcaps. She's a looker. ;) Two shots with a 22 fpe Talon P .20 cal no moderator, then two shots same rifle same pellet with the Ember and finally the sound of the pellet impacting on the...

Took a few samples today of the BSA GRT shooting 31 grain Baracudas. I wanted to look at the shot spectrum and see what I could figure out about the timing of certain events. It is proving to be interesting so I am going tg document that work here as I do it. EDIT: Done. Lets have a look and...

Today when I was testing I pulled out the Donny FL Tatsu and ran it beside all the other moderators and the bare rifle. I located the microphone 31 feet from the muzzle and 33 degrees (11 o'clock) left of the muzzle. This was done to reduce clipping. I still experienced some minor clipping...

@WobblyHand has been kicking around the idea of a moderator "chassie" to use when developing baffles so that less printing is involved and you can compare apples to apples on the test range. It is a great idea. I have one in work. When I have something good enough to put out to everyone I'll...

This is Mamba #1. It has been my personal moderator for the last couple of months. It has been continuously shot on a 63 fpe Condor since I printed it. It's been one of my standards for testing. I sell these at $65.00 TYD but this one is used. Special Deal $45.00 To Your Door This unit...

Regarding the rifle itself HERE and HERE Regarding the moderator itself. Intro Red is PETG and black is TPU. Well now! This is interesting! I do think I shall have to revisit my design. Here are the five test samples, one shot each, 60 ms of each shot. Score is Airforce one, Oldspook...

$50.00 To Your Door It is marked down because I am trying to clean out some of these moderators so that I can work on the next generation. It will easily handle ANY 177 caliber rifle out there. I've shot it on a 60 fpe Condor (with no pellet). This little moderator is 97mm long, 35mm in...

STO defines flow factor as: ((Start Pressure (BAR) - End Pressure (BAR)) * Tank Volume CC) / Shots Fired The units of this value are BAR per CC per shot and can be converted to (or given tank capacity derived from) PSI per shot. This is brilliant because you can report this number when you...

I posted yesterday regarding my Talon P and got a question about the moderator. Also posted about the rifle here earlier this month. I ran the test on it today. The video is plagued with wind noise and not really worth watching. The question was how well does it work? I shot three shots...

In her natural environment. 😉 Printed this dovetail rail on my resin printer. The attachment for the sling is off the shelf. The rail attachment epoxies into place. It could be modified to use screws and a screw plate. The front sling mount is off the shelf as well. The rifle is...

Yesterday at this post we started kicking around this idea. So I made one and tested it. Not bad. 😉 Here is the audio, stripped and set up for comparison, three shots bare, three shots unwrapped and three shots wrapped. Here is the graph of that audio. I cut the graph off at 10 kHz. It...

You can probably find one of these at your local hardware store. In the future I'll just toss one in each package. :)

Well, disregard my frustration with the v1 safety on that "Condor" I own, Clearly that problem is ancient history. I received the "Talon P" which is a newer version and this will come as old news to most of you guys but the differences are not cosmetic. They fixed literally every complaint I...
