General Airgun Forum Discussion / Re: This forum is the greatest

It was all my pleasure! 

This is the good part about the internet. You make friends online, and then extend that to in person.  I did the same with a boat building forum way back in 2000. Met good folks from all over the world,  which makes it a much smaller place.

I'm not sure what's more disturbing...the rat or the slippers.  ;D

Of Course they show up after we leave.  Would have loved to have popped one when we were there.  Thanks again for opening your home to us.

Prime Rat Killing time is from midnight till 5am. You are welcome to come hang out and kill rats. Of course once you take a shot, it takes on average one hour before they come back. Their network is amazing. "DANGER the assassin is out and about! Make yourself scarce!."

Hajimoto's Airgun Annex / Demonstration of Accuracy (MROD vs Dragonfly)
« Last post by Hajimoto on Today at 09:12:10 AM »
Hey fellas!
I realize that while the video I am going to share is not officially hunting, it does depict a projectile taking out a living creature which technically can only reside in this forum.  The following video demonstrates the accuracy of my MROD GEN2 .22cal as well as the ability to capture the action using my HSCA (Hajimoto Scope Camera Assembly). 

  • The first target is a small dragonfly that landed on the top of a black zip tie which is holding my IR flood light to the pole.
    The second target is a piece of masons nylon string hanging from a board down range.

Both targets were 45yards down range. Share your thoughts on this thread, lets talk about it, lets see your Dragonfly hunting videos  :D


Always remember guys, I do not get paid to make these videos, your comments and feedback are my compensation, please be generous!


Thank you!

Ask Bob / Re: Balanced valves in pcp's
« Last post by rsterne on Today at 08:27:13 AM »
Tim, I don't really understand the drawing, or concept.... Is the valve at the left?.... Is the main hammer spring inside the hammer, with the preload adjusted on the right?.... From your description, it seems that this would only be useful in a regulated PCP....

The theory behind the electrically-controlled valve is consistency. Daystate's version is perhaps a step forward, albeit a complicated one. You could do much better using a piezo-controlled valve, but the electronics would get somewhat more complicated. So I predict....

Once the balanced valve becomes well known, and widely used, the advent of any electronically-controlled valve will be put on the back burning for a lot more years!

So far, thankfully, the things we don't have here are brand singularity, and inflated egos surrounding same. If we did, it wouldn't be the learning institution that it is now. We are all blessed!

There is a "heli board" I think its called out for these in .177 and .22 Guys are getting like 12 power settings and other adjustments they really like. I emailed the guy that makes them to see what it would do for my 25. He said the he may be able to get the FPS up close to 900 but the shot count would go down to 12-15 he thought. He had not done a board for the .25 but thought they were the same as the smaller calibers. It would be nice if the AW would should the 25 grains mid 950 and the 34's at 850 on high. Low power for the 34's would be mid 850 and so on...........But that's not how she's made. All that said? I don't think a 30 cal conversion is feasible. But good hunting!

Lets say I found a way to open up a valve mechanically using "spring-method" and be able to tune it to be fully balanced at any pressure. Anything lower would just leave it open like some other "pressure" reducing valves. And can be filled from empty.

I just don't know if it would be safe or advantageous to other balanced valves. Theoretically, it will be easy to open but I can not see it closing as efficiently unless you think otherwise.

The drawing is complicated to me but, you may understand it. The hammer rides (slides) on a stem that is connected to a rigid hollow stem connected to the cap which has a screw to increase or decrease valve stem load.
For tuning,
Decrease valve stem pressure to neutral and charge the gun to 200psi higher than what you want it to fully balance at. Screw in the screw to load the valve until air is released and finally stops at desired "balance pressure". This is the pressure that you should never go below before dump.

Just don't know if it would close fast enough to be efficient. What do you think?
