I mentioned trigger for a reason—I'm spoiled! My favorite airgun is my WAR Cobra, replete with Timney Calvin Elite trigger group. It is as crisp as any trigger I've ever used. I like Canjar too, because they make the best single set I know of. A bit of background.

About 30 years ago, I inherited a company called Triggersmith. The main thrust was to condition the support surfaces of the trigger with Tungsten DiSulfide (aka Danzac). My father started the business about 1950, and he almost patented the technique. Alas, that never happened, and the support surfaces of triggers has improved tremendously over the years making coatings all but unnecessary. So I sorts kinda maybe know a bit about triggers.

So, my comments about most stock airgun triggers can be summed up in one two words—universally lousy!

You outta try my Sumatra and 909s triggers. Absolutely Horrible. I keep meaning to take them apart and polish, but time....

My comment is that when I see something I want and I buy it I do not want to wait 6 months to get it and don't want to be lied to at every turn.  I think customer service and satisfaction is the best.  It's ok for one to ask what someone likes to have but they don't need personal info until you order the product and know for sure that it is ready to sell.  Just my 4 cents for inflation.  Probably off target and sorry if I stepped on toes but good luck

Well, at least I didn't watch the same hit about 10 times! Just you wait! You'll like the night time video from the X-Sight II.

You are welcome!

Yes, it is heavy, or about twice that of the Photon, but then again, it doesn't have the bells and whistles the X-Sight II has. Depending on your point of view, that is either good or bad.

The scope in night mode, has three pigs, two coyotes, and one fox to its credit. Daytime? Lord knows how many doves and pigeons I've shot with it. I did make a few movies of the various hunts, button as a regular thing.

Fact is, I'm a bit putout by most hunting videos because of the loud and in a propriety music, endless repeats in fast and slow motion, and extremely poor editing. Folks should watch Hajimoto's videos if they want to see how it should be done!!

Enjoy my friend!

oh goody, the scope is experienced! I know guys who have bought a boat because a lot of fish were caught on that boat. Silly. Maybe.

I shoot these dinky up to 25 second videos with zero editing, no titles, no music, and only the smack of the pellet for sound. Suits me fine. I just don't have the time or desire to sit and edit video. At one time in my life I actually did that for a living using the old fashioned uMatic video format, insert and assembly editing, complete with sound track and titling. I'm over it. Well, for now. Perhaps this ATN will trigger old desires.

Life is good!

Here's the rat I killed this morning at 1:30am.
. I hope to have another kill or two this weekend and share a slightly different viewpoint!

I have "known" Bill G (on the internet and through emails) for a couple of years now.... He has a Corbin bullet swage setup, and a knurling setup for airgun bullets, and I helped him with a couple of BBT designs.... It sounds like he is getting more serious about producing a wider range of items for airguns, and I wish him all the best.... I think market research is a good idea, instead of blindly taking off in a direction that HE may believe is the right one.... but carries little interest from the shooters.... Perhaps if you don't see something in his survey that is of particular interest to you (like triggers, as Alan mentioned).... adding your comments in this thread would be appropriate....

PCP, C02, and Helium Powered Airguns / Re: Tale of Two BRods

Today I tested the ART/SS valve without any jet on the inlet side.... just about a 1/8" hole there.... I still had the preload on the 8 lbs. hammer spring on the SSG set to 0.40" (about 3.2 lbs).... I tested the .30 cal version with the 50 gr. pellets at 1900 psi (only), and realistically there was no significant difference with the jet removed.... The valve still took very little hammer strike to open it.... So, I then swapped out the MDS hammer with the steel core (51 grams) for one with an aluminum core that only weighed 27 grams.... For some unexplained reason I lost about 10 fps from the maximum velocity (which I would not tune for, it would be too inefficient).... but as expected I now needed less SSG gap to get to the cliff.... Here are the results, compared to where I started with this valve (black line)....



Changing to the 0.40" preload from 0.60" is what moved the top of the cliff from 9 turns of gap to 8 turns.... I didn't plot that curve because it essentially tracked the black line except for the earlier cliff.... You can see that with no jet installed (purple line) there was less of a "knee" to the curve.... still some, but there was less velocity adjustment before you got to the cliff.... The same setup but with the 27 gram hammer (the orange line) shifts the cliff to only 5 turns of gap, but I can still reach the plateau with 1 turn of gap.... This gives me an adjustment range of 4 turns, and makes the amount of gap where I would adjust the gun just about where I like to see it.... around 1/8"-3/16".... The only way to reduce it further would be a lighter hammer spring, or reducing the hammer stroke.... I can actually DO that with the aluminum cored hammer, as it has a steel setscrew insert for the striker (currently set flush).... One other thing I noted with the very light hammer.... The range of velocity adjustment between plateau and cliff increases significantly.... leading me to believe that light hammers and this valve would be a great combination....

I did one "efficiency run" by shooting one 7-shot magazine with the velocity set to just over 900 fps with both setups.... Small changes in the exact velocity make big changes in the efficiency at around that velocity with these big ports.... but essentially I believe there is little difference in the efficiency if the velocity is the same with the jet removed.... HOWEVER, it does give you less velocity adjustment just above the cliff, and if you are tuning for efficiency I think you would struggle to get the best combination of power and air usage without the jet.... If all you are interested in is pure power with a light hammer strike, however.... this valve is a BEAST.... It requires MUCH less hammer strike than even the Cothran Powerhouse valve in the testing I have done so far.... I'm impressed....  8) 8) 8)

Welcome, and enjoy yourself.

I started to reply earlier, but thought better for an obtuse reason. That said, I agree with Steve about the personal data. None should make a difference in my opinion—either you're passionate about airguns, or your not.

There are several things your form didn't ask about. Regulators and suppressors to name two, and one I'm passionate about, good triggers! A good example is a recent post by Hajimoto about modifying the Gauntlet's trigger. While the video is very well done, the question remains, why aren't manufacturers getting the message? Sort of reminds me about automobile enthusiasts—they want to know how fast the vehicle can go, and couldn't care less about how quickly it stops!

Big Bore Airguns / Re: Quackenbush .575 short rifle
« Last post by Guthook on Today at 10:52:02 AM »
Yeah I understand saving air for a few more fills. Big bore airguns don't get a lot fuel mileage. I'm anticipating a 3250psi fill based on your comments. Hopefully that will give 2 shots without dumping before the fill .   Filling from empty takes more air than adding 250psi to the max fill.
