Not wrong at all, check the real science from manufacturer's of breathing air compressors and filters. Check the labs that certify breathing air, research a little and don't be stupid. It is absolutely scientifically documented.

it looks like those are molecular sieve beads and are in direct contact with metal, if so that is a huge fail, in short order corrosion will be seen on the metal in contact. Piss poor design, and won't last.

I have, many times until a friend of mine died. Wasn't uncommon for the two of us to go through 20k rounds in a day, and if half the sheriff's office was there a lot more. PB's, full auto, from thompson's up to a 30 cal mini gun and an electrically operated quad 50 cal. Good times. Air...

@Ballisticboy , I can think of several projectiles and twist rates that absolutely are opposite of what you just said. One example, 8 twist, nosler 30 cal ballistic tip, launch at under 900 fps and guaranteed it will yaw horribly and make an open choke shotgun look like the most precision...

It wouldn't be, never crossed my mind someone would want one as a trophy. Squirrel=rat to me... Legal where I live to slaughter them year round if threat to my home, with 2 pecan trees close enough to my house they could jump from the trunk to my roof, that is all I need. I shoot them as...

2x4 set up as a 45 degree ramp up a tree trunk, rat trap screwed to it, a few peanutes(in shell or not) on 2x4, one on rat trap trigger. Dead squirrel, open jaws trap take pristine squirrel to taxidermist.

@Gwhite, cut those degrees by about 1/10th and you are in the sweet spot, and it makes a massive difference. Literally, a 2.5 foot error in aiming the center of the beam at a target 100 yards away drops the radar return by several orders of magnitude. If you have never seen your SNR hit 40 or...

@AlanMcD SNR is more complicated than just a value. For instance, you mentioned a SNR below 25 in your situation can easily lead to be bad data. At my good range at home, I need near an order of magnitude better than that (27), and on my bad range at home I need a SNR of 30-32+ to get good...

I'd have to disagree, it is a choice not to know and that says a lot about the person in my book. That was me in 1995, the part of wanting an air rifle, not the rest. I probably already had 30+ firearms, most high end and I could not use any for what I wanted to accomplish. I knew what was...

And a slug is what? Let me help you there..... 32.17404 lb, wow, gravity again.... How do you think it is derived. Whenever science talks about weight, it is all based on gravity, full stop. It doesn't matter what units they use. There is no weight without gravity, and standard gravity is...

If you haven't already, download the labradar individual shot traces from the sd card. With the labradar set for subsonic range, the trace should be every 0.002 seconds. It will give you time, distance, velocity, and most important Signal to Noise Ratio (SNR). If the first few yards it picks...

For those worried about alpha glass parallax settings from the standpoint of ranging in field target, you are likely barking up the wrong tree. Most if not all alpha glass is very forgiving on parallax(has a huge depth of field in general on alpha glass), the exact opposite of what you people...

When discussing foot lbs, which is the standard use of muzzle energy in the United States, gravity is needed to calculate, changes mass to weight. But you knew that already so why post what you did.

That number can be found to be different in many places, sometimes rounding differences, one time long ago it changed with a more accurated definition of gravity. The number is basically 7000 grams squared * acceleration of gravity in ft/second squared. It doesn't matter, anything close...

It's been through at least two formulations, likely a third. Originally it would produce a pinkish bubbling surface when applied. That formulation is long gone along with the wipe-out electrolysis unit that worked great. In the case of electrolysis, I'm surprised they ever made that unit(I...
