Testing new discovery

[KnifeMaker]

I have several members here testing their own handmade devices and so far success. And more have been added to the test team.


I believe Travis plans to test some this weekend. We are trying different version, and other than already ultra accurate combo's and guns, it has made a marked improvement.


I received an email with more results from two members here, and would very much like for them to post the results I think everyone would be very impressed.


I will give DonnyFl a little while longer to decide and would encourage members testing to email Donny and give him the results as well.


It can only help the cause.


This is taken from the casting section of the forum here.

  Keith, I had another bullet here that didn't shoot so well. In fact not well at all.  It was a shortened NOE RD, that had been cut down to 50 grains, and large HP by Hollow pooiint mold services. (Eric). It was stellar at 80 grains in the Talon/Dor.
  
  
  Since the same bullet shortened ever further, to 44.6 grains shot so well after the device test, I decided to give it one last try. Nope, still not good. Much better but not up to standards.
  
  I have over 300 US bucks tied up in the mold, and it was now virtually a huge waste. So I decided to bring it down to the same dimensions as the bullet that is doing so well with the device installed in the RS II.
  
  
  First shot was 994 fps, but as you know, a fast miss is well, a miss. Fired three more,and was rewarded with a nice clover leaf. It hit a bit higher, and to the left in the north wind. Adjusted right, three more, adn a nice clover leaf exactly where I wanted it but high. One click down, and bingo. Reloaded and shot 5 and was rewarded with a very nice tight group that was basically one ragged hole. Woo-Hoo!!!
  I wonder what it could do with a good barrel.
  
  
  This HP weighs in at 39.5-6 gr's. And gave another two shots before coming off the reg.
  
  
  Hopefully I can have a plenum made for it eventually, as it is only 30 cc's. far too small.   Which has me running the Reg. maxed out at 175 bar.
  Hubb at Huma told me it would wear out the bevills, but he said, so what. they are cheap and we have plenty of them.     
  
  
  I can't wait to try this little Hi Stepping little pill on a varmint. The Cavity is HUGE, well pretty much like what you just cast! Woo-Hoo!!!

A quick note, IT WORKS,
went from 1-1/2 - 2 " groups, using OEM 14.3 CM pellets, still have POI/POA shifting @ 40 yds, 
on this 22 cal Gauntlet, 1320 psi reg set point,
to nickle sized, 3 shot groups @ 40 yds, NO changes made to anything, except using Mikes information etc.

Ran out of air, refilling all 3 SCBA tanks, more testing tomorrow.

Tia,

Don, this is great news! I really didn't think it could do much for light pellets. It works very well for bullets of just about any weight so far with thesters out there.


I did get to try out the new light HP on a trash bird today. Normally I give the shot birds to my fox. However, it looked like a pillow fight when it hit. There was no meat left. None. It virtually exploded.


I tired the HP at multiple ranges today, and it seemed it couldn't miss. Man this thing is shooting! Finally I have full confidence in the RS II shooting bullets.


I have a RF silhouette (steel) set that I like to use. At 80 yards, I shot what would be the eye with a 3 shot group. It was smaller than the club's on a playing card. Tiny ctc. Woo-H00!!!


Gotta love it!

So how does this perform for the 10-13ft lb crowd?

Some countries are limited to sub 12 ft lbs.

And some of us here in the USA use SPECIFIC ft lbs for indoor pest work where over penetration is NOT an option.

It probably doesn't. If your gun is having harmonic problems at such a low power level, and such short ranges with pinpoint accuracy, you are having serious problems with your gun that need to be address, or move on to another platform. This in not your huckleberry.   


This in not an end all, fix all for every platform and every thing that can cause issues in an AirGun out there. Other issues must be addressed. Actual mechanical accuracy and precision of both the gun and the shooter. These much be addressed by all.


At those type of ranges and low power, it should be pellet on pellet. If not, there are issues. Gun, Shooter, both? It is you job as the shooter to find the problem areas and address them.


This system is aimed primarily toward higher power AG's, with heavy pellets, higher fpe, and slug shooting., However, a few testers have found success with mid power pellet shooting as well.   


There seems to be promis in more applications than I would have assumed.

There is no problem, with the Airforce platform at sub 12 ftlbs.

 I was just asking as I keep seeing responses about this projectile going from X inch group to Z sized group.

But no real discussion as to what is being used or done to achieve this.

Early in this thread there was mentioned something to the effect of that this would be beneficial to the airgun community as a whole.

And in the vague discussion of what is going on, the power levels haven’t been really discussed. 

Not everyone in the airgun world uses a 80ftlb gun with a 30gr projectile to kill a 2 oz chipmunk at 15 yards.

I would venture to say that 95% of the members of the GTA, shoot sub 12ftlbs.

And that is why I was asking about the power levels.

But thanks for telling me my gun has problems, and I can’t shoot, just because I asked.

More than likely, there will be now such reveal until DonnyFl decides if and when he wants to bring it to market.


At that time, I will be more than happy to give ways to dyi as well.


There are many ways to enhance the AF platform.  First and foremost, is an aftermarket trigger.


Next, put a decent stock on it that braces the bottle, as any pressure in any direction what so ever can change the poi. This happens to the best shooters when using different positions while shooting.
A scope rail brace helps a bit, and is sold by AF. A madDog stock cures most of the AF limitations. 


I have mine shooting under 1/2" at 100 yards. Many groups under 3/8". Tofazfou and Doug Noble have been able to go well under an  inch at 200+.


Yes, they can be very accurate, and what i am playing with, and others are testing could very well help in precision. However, until AF sees fit to thicken the cut out material in the breach, they will continue to be far too flexible.


This has been discussed with AF by some of the top shooters in our industry for years. As usual, AF ignores any input and has from their beginning.


Badgering me to give info that I clearly stated could not be given yet, and why, in the first post on this thread is not going to change my mind. Period!


Take it, Leave it, Troll it. Whatever you enjoy the most.

  Will this mod be useful to those of us unable to use a moderator? Sounds like this is the case.

[KnifeMaker]

Yes it will. Infact, Hobbyman is on it as we speak.

Good to hear.

[Nomadic Pirate]

Whatever it is hope someone brings it to market
( how hard is it for Donny to make a decision at this point ? )

.......I probably could order 1/2 a dozen right away

[45Bravo]

I was not badgering, and was not trolling.

I just asked a question about would it help low power guns.

And I got squashed like a bug. 
Thanks.

Oh, I agree on the shortcomings you listed for the Airforce platform.

And have been in place on my working gun for a few years.

Ian, i think knife was just addressing the 12lbs crowd in general should not have accuracy problems out to 50 yards. if they do, then its the gun, the shooter or the wind. you shouldn't take it personal.

the 12 flbs  guns are not violent enough for it to affect down range accuracy.

there was a report of a gauntlet 22 running 1300psi should not exceed 30 flbs with 14.3gr crosman pellets. and accuracy was improved...so it could help if the device is used. 

i am sure the secret will be spilled by Knife himself if no manufacturers want to dive in. i would rather wait for a tried and true version also, that way as an end user...id be happy

I’ve done more testing today . Extremely windy as usual for springtime in my neck of the woods . First up was a Frankendisco .25 cal sporting a LW barrel that typically prints small groups out to 40 yards using the 25 grain JSB at 750 FPS ( low power tune ) . The JSB pellets didn’t improve at all , the H&N Hunter extremes however , group shrank from a 1/2” group at 30 yards to one single hole . They actually shot better than my usual JSB. This just goes to show maybe your favorite pellet isn’t the best pellet.
Next up was my second Frankendisco in .22 cal sporting a Hatsan BT65 barrel . I hadn’t shot this one since installing the Hatsan barrel so I didn’t know what to expect. Shooting the 15 grain JSB at 650 fps to 30 yards again . All groups with or without gizmo were all single holes . I’ll have to revisit this one at longer ranges to see if there’s any marked improvement . Both of these guns have their barrels free floated other than a barrel band butted up against the breech .

My findings so far . Hi powered , free floating barrels ( non tensioned) tend to see the biggest improvement . Anytime using heavier ammo , bullets or pellets again show the biggest improvement . From today , a low power mid caliber rifle can still see improvement . No significant improvement in low powered small caliber pellet shooting at close range .

FYI, whether Donny brings it to market or not ppl will still make their own (since it is apparently so easy to do).  Just spit it out already man, we're dying here!

[bear air]

I guarantee if Donny brings it to market it will be top notch and worth it. I hope whoever figures whatever out soon so us regular schmoes can get in on this big break through secret!

Good looking ring!


Find a piece of sole leather, or neoprene type shoe sole, apx 1/4" thick or a little less. Any shoe repair will have it. Place it between the rear of the bottle and stock. This will prevent the tremendous leverage the bottle has on the very week bottle attachment point, which flexes the breach area of the frame. I used conveyor belt material and permanently attached it to the stock. Huge improvement!


Before even doing this, you can check the issue yourself. On the bench, shoot a norman group. Now lightly pinch the bottle on the very rear, and the stock together. Now use more pressure with each consecutive shot.  Also light side to side pressure. You will see the poi wonder. 


You will see an instant improvement in many shooting positions and styles.


Doug of MadDog incorporated this in his stocks, (same principle) after I discovered the benefits, and Tofazfou and Dayotat100 proved it out.


He also incorporated the rear leg rest. I was doing it before Atlas or any other that I know of. Very handy. I do now use the Atlas however. Very expensive!  Seems every body and his brother has a version out now. LOL


the reason I got on your case, is this is the second time you have done this. It was pointed out by other members here that the reason I didn't do it was called integrity.


Still stands. I would appreciate very much your not getting on my case or putting me down  for keeping my word to an old friend. DonnyFl.

Been a couple weeks since the last post. Requesting an update on how things are going.

[bear air]

+1 as well. Anything new to be told yet?

[KnifeMaker]

I will call Donny and see if he is going to incorporate the items in his lineup.


Travis is also testing for possible use with the  JSAR Raptor.


I have been very busy with my wife and her surgery. However, I did manage to test further today. All bullets improved but one. it actually shot better without the device. GRRRR!!!


Like barrels, it likes what it likes.


I will spill the beans with in a week.
