Hello Gray...When you offer this rifle to the public and customer orders one from you how long will it take to complete the order for shipping...kind regards, Allen.by allen avram - Airgun Rendezvous Main Forum
Hello Gary...Do you have any pics. of recent guns built...kind regards, Allen.by allen avram - Airgun Rendezvous Main Forum

Hello Florida...thanks for the reply...Our shop makes high performance parts for the snowmobile world...specifically parts that are part of the snowmobile clutch that spins at 10K rpm and they need to be exact and weight the same to keep balance...thats the kind of duplication I'am speaking of...now to want to duplicate Gary's Alpine I have no interest in doing that but there is the technology ouby allen avram - Airgun Rendezvous Main Forum
Florida...I read your post regarding duplication of parts...I want to make clear on your "NO" one can duplicate comment...anything can be digitised and downloaded to duplicate if that what the machinist is looking for...what Gary does free hand "old school" I agree with you...Hmmm.Shaper? Is it something like this? Allen.by allen avram - Airgun Rendezvous Main Forum
Gary, you rank up there with Theo Hegman and Girandoni as far as master craftsman...It is wonderful that the air gun world today has a master like you producing these masterpieces...I hope you have a family member or someone that you can pass on your expertise on to for future generations to enjoy...Allen.by allen avram - Airgun Rendezvous Main Forum
That ball on the end of the shaft thing...spent 65K for a CNC lathe that the computer does it for you...wish it was only $30.00 haha...Allen.by allen avram - Airgun Rendezvous Main Forum
By golly Gary that 1 1/4" $30.00 cutter does on heck of a job makin a channel...those ball end mills do get very pricey don't they...You are doing a fine job there on the wood and the metal pieces are beautiful...Allen.by allen avram - Airgun Rendezvous Main Forum

Did a little more testing with helium with a 4000psi fill with 200gr solid hunters supply .408 sized bullet...we adjusted the valving to completely dump all gas from charge tube with one shot just to see what velocity would be. Here is the data...1380 feet/sec. with 845.7 ft./lbs energy...we placed a 1/4" plate steel target at 55 yds and put a hole completely thru it...Allen.by allen avram - Airgun Rendezvous Main Forum
Hello Gary...I don't think the valve opens easier, you still have same psi. pressing on the valve head no matter if it is air, nitrogen, or helium it is the same, what is different is when the valve is open when fired more helium will get past the valve opening as compared to air or nitrogen because the helium gas is less dense...hope this helps, Allen.by allen avram - Airgun Rendezvous Main Forum
To answer some questions Gary...Valve lock last year with nitrogen as opposed to higher psi helium...good debate item over coffee, your guess is as good as mine....overdrive valve mechanism: We never had any issues with hammer/valve because when testing with a chromograph when velocity fell off alot we just stopped shooting and refilled with gas...I'am sure that common sense comes into play thatby allen avram - Airgun Rendezvous Main Forum
Thanks for all the comments gentlemen...years ago when the only gas available was the CO2 cartridges for a power source and then came along the PCP's and that was a big step in the capabilities of air rifles. A few years ago I heard of a few fellows trying helium as an alternative but I never was able to get some hard numbers for comparables and this is why I thought well lets give it a try andby allen avram - Airgun Rendezvous Main Forum
When testing with helium our goal was to use a bullet that shot good groups with compressed air or nitrogen...We found that Mr. Hollow point (Bob Vogel) .230gr/.40 cal worked great. This bullet weight would be good for just about any game that you want to hunt, now if all you have to do is change gas to increase velocity by about 200fps and the gun shoots flatter with less holdover now you haveby allen avram - Airgun Rendezvous Main Forum
Here is a formula for you....FPE = (fps)*(fps)*(wt)/450240 880x880x230gr./450240= 395.59 ft. lbs. energy -----Nitrogen 1080x1080x230gr./450240= 595.80 ft. lbs. energy ----Helium shot count goes down with helium...you may have to test your own gun to see how many shots...We can get two good shots with helium compared to four good shots with nitrogen see my post re: cost of helium, it isn'tby allen avram - Airgun Rendezvous Main Forum
Good morning everyone...We did some more testing yesterday...3500 psi charge of nitrogen, .40 cal/230 gr. hollowpoint, two shots@880fps. 3500 psi charge with helium same bullet two shots 1080 fps...hope this helps, Allen.by allen avram - Airgun Rendezvous Main Forum

Mighty fine shootin there Jerry...Allen.by allen avram - Airgun Rendezvous Main Forum
Kudos to Crosman for R and D on this gun...setting a new benchmark for electronics...giving new insight to the airgun world...this could be a modders dream...just my thoughts, Allen.by allen avram - Airgun Rendezvous Main Forum
Happy New Year Gary...Archery target shooting...now that brings back some memories...shooting a perfect 300 was really something, then shooting 60 spots really was a perfect score...never made 60 spots, best I done was 300/50...anyway here is a great website for you Lon...Check out the Clarifiers, Lenses, Dots and Circles...everything you need to be on the cutting edge of a compound bow scope plaby allen avram - Airgun Rendezvous Main Forum
Happy New Year Lon...If you want to go high tech, talk to you eye doctor and have him put a -3 lens in your rear peep and a lens in your muzzle end sight to get magnification to whatever power you want...I had mine set so @ 20 yds the scribed circle was same size as 10 ring on the bullseye...eye Dr. will have to know distance of eye from peep and distance of peep to lens at muzzle end....1x to 15by allen avram - Airgun Rendezvous Main Forum
Years ago when I shot target bow I used for a front sight a clear lens with circle scribed on the lens and it worked great...if you have an old watch you can use the lens from that and cut to fit...hope this helps, Allen.by allen avram - Airgun Rendezvous Main Forum
