Testing new discovery

[mr007s]

I have not weighed them but will. The pack had 50 and I have 30 still left. I will post weight tonight.

Neat Idea with the "O" rings. Question for you,

What does 20 of these "O" rings weigh, total weight?

Tia,
Don

Wondering the same thing...

20 weigh 34 grams which is right at 2 ounces.

Does the idea come from what I have state earlier in this tread..
2 oz is light enough to be carry with no problem …. And can hunt with it..

[mr007s]

No, I don't believe it did.

Did some more light pellet tests with the oil & lead shot filled bottle.  Tried different amounts of shot, with the rest of the space taken up by oil and a small air bubble.
It's a small sample so i'm not sure this is very conclusive, but it looks as if around 4-5 oz of damper weight worked best for my At-44, with 14.3 grain pellets.
The shooting was done in the order shown below.  I think the general variation in group size (the without groups) was bigger than any change caused by the extra weight on the barrel.

Without: 2.6" group
With 4oz: 1.3" group
without: 1.5" group (the gun or I warming up at this point)
with 5 oz: 1.25" group
without: 0.9" group
with 6 oz: 1.9" group
without: 0.79" group (repeat)
with 6 oz: 1.08" group (repeat)

Very interesting groups size and info, Question for you, What was the fps for this testing?

Between 4-5 oz rating seemed to be the changing point, in group size, for your rifle/loading etc.

If possible, can you re shoot these same tests, and starting at 4 oz,
increase the weight by 1/4 oz per test, keeping every thing the same as the first test etc.

Then you can see if a greater increase/decrease of the group sizing etc,
occurs with just the quarter oz weight increase.

As another thought/test, find the worst accurate shooting pellet, and try your test on it,
it might prove to be worth the testing etc.

Holy Snackbar Ray,

Are you sure that those "O" rings are not made from lead.................    

Kinda hard to believe that weight for "O" rings, if you know what I mean,
(No offense meant or intended).

Those "O" rings av 26.385 grains each!!!!!!!!    Are these the Hard or Soft "O" rings?

28.3 grams = 1 oz   1.7 g each      seems high

Good catch, my mistake! Meant to put a #1 in front of the 2 (weighs 1.2 oz. THANKS

The gun is tuned to shoot the 14.3 grain pellets in the 860 fps range.  I will try a more gradual approach on the weight increase next test.
I also want to try a different weight oil (thinking something heavier like gear oil).  I think I need a better fastening method too, the masking tape is quick easy but not to consistent or secure.

Thanks Rich

Here is some clamps that works very well on round MAD devices,
they come in several sizes/dimensions etc,

This is the lightest clamp, I am using,

Rich, your best two results appear to have been without the device, am I correct?.... Not only that, if I throw out the first group (which was twice the size), and average the other three groups without, I get 1.06".... which is smaller than any of the groups with the device....

I will be interested in seeing your results with smaller weight increments.... and also with heavier oil.... in particular to see if you can come up with groups averaging under 1"....

[Lefusil]

Yes, you are correct Bob.  I think the results of this test have too much variation to really make any definitive conclusions.  No biggie, I need to change some things and keep trying.

[rsterne]

I had the same results....  inconclusive but worth more testing....

Here's one negative point of the device after shooting some 200 shots with it. I had my device hanging on the silencer and eventually the weight and 150 fpe shots caused one of the screws in the silencer adapter to come loose causing slight droop on adapter and clipping on baffles. I took the device off from the silencer and hung it on the barrel after fixing the silencer and the adapter.

After reading all the good posts on this, I decided to give it a try.  I liked the mercury idea best, so I ordered one of the C&H recoil reducers and securely taped it onto the bottom of the moderator on two of my guns, both .22 caliber with shipping tape (it is very secure that way, and easy to move between guns for testing).  One gun was a high power Marauder with an LW Poly barrel, and I tested it with JSB Beasts at about 815 fps, and Monsters at about 920 fps (it shoots the Beasts poorly and Monsters quite well - I was really hoping to see improvement in the Beasts.  I also tested it on my Air Ranger, shooting AA 16 grain pellets at about 900 fps (it stacks them to start with). I was shooting at 55 yards, so there was plenty of opportunity to see any improvement

I had hoped to show groups with great improvement, but there really is no point in showing anything.  Other than a lower POI, I saw no difference on the Marauder, and if anything I saw an increase in lateral dispersion on the Air Ranger.  I did lower the power on the Marauder (it is regulated with a TSS, thus easy to adjust on the fly), but again no real difference.

I will probably try a few other things with it, but I am sad to report that I did not see any benefit, and maybe a slight degradation on one gun.

[chwillbill68]

Boy what a read!  You guys have so many different methods I am not sure which one to try.

[mr007s]

Giving this thread a bump, been a spell since any post. Wondering if anyone is still testing?

[Nvreloader]

I just got LL> Leakin Lena back in shooting form again, and just put another copy of the Mercury of the MAD on it,
using the magazine clamp and hung right under the air stripper.

I am curious if it will work just as good as on the Gauntlet.........getting Dime/Nickle sized 5 shots groups at 40-50 yds...so far.  Waiting on some CM Domed headed pellets to get here.
