The 2260 is no longer made.... and the tube is too short for a decent volume pump anyway....

I'm focusing specifically on my prototypes as stated with my build specs...I'm really not going to entertain any other options at this time.
Bob built a fantastic rifle and I want to improve upon it with my custom top end - the design deserves nothing less.

That's why the thread reads 'High Quality' and I've made a direct challenge/comparison of my top end to $2500+ air rifles.

I'm trying to come in under $1000 - the whole 'its a Disco' premise needs to be dropped and forgotten about.

This may use a Disco pressure tube and and have the overall basic design regarding valving and power train function but this is an ENTIRELY different Beast!
I can buy a Disco pressure tube from Crosman for $25 and most of the work is completed except the few holes and milling a slot for the pump linkage.

If I was to buy raw tubing and have to mill and drill all of the needed slots and holes for the entire gun, that tube just went up in cost by 3x...

The premise is to use commercially available inexpensive (not to be confused with cheap!) parts so machining time is at a minimal.

My top end is where all of the accuracy magic is going to happen!

Why spend the money on a 'basement' model just for a MSP if its not going to be insanely accurate? It might be *cool* - but I don't want to let myself get sidetracked until the prototypes are built and tested and we produce an initial run of guns built to my specs.

Once that is done then I will take a look at other options.

+1

Thanks for that. I would not be interested in a cheap model, other wise I would have built one myself. I want something I can pick up and shoot accurately as soon as I get it.

I'm in for a pumper. Whats not to like, American made, high performance. Regards, Tom

When I get my custom RAW HM1000X I will shoot the Millennium head to head against it out to 75 yards.

I will tether the Millennium @ 1800 psi and tune the RAW down so they are both shooting 50 ft lbs.
Both rifles will be regulated.

They will both have my 1:22" twist 9/16" OD barrels sleeved in CF...both fully free floated.

I will tune the Mrod trigger to 8 oz so it can at least try to compare to Martins trigger.

This will be a *SOLID* test of my breech assembly against a well known $2500 top shelf air rifle (the base RAW is $2k and I'm having quite a few custom things done to mine).
The only real difference (other than obvious powerplants and my breech/barrel assembly) will be in barrel leade/crown prep and my sleeving process vs how Martin does it.

Not knocking either rifles build specs - it will just be to prove that the Millennium can hold its own against the best air rifle available.

.... Even at twice the price of a Disco, it will be less than half the price of an FX Indy....

Hmmm, I'm wondering: more buyers ... the lower the unit-price?!?!?!?
As a small-batch custom-made production run, probably ... NOT.

Even so, at half-the-price of an FX Independence ... which, being a married man, I can't justify ... the Millennium pumper may turn-out to be a practical and affordable alternative.
A domestically produced ... Poor Man's FX Independence.

It is about time a U.S.-sourced, Made-in-American, premium-quality MSP became available in the U.S. and clip-feed is the icing-on-the-cake.
I hope there is enough interest to warrent production.

And will tide-me-over until the Webley single-stroke Paradigm ... if ever ... comes to fruition.

This sounds very interesting.
Your price point seems way more than fair for a custom handmade gun.
Chances are I'll pick one up from you.

cclingma · « **Reply #47 on:** October 19, 2014, 11:10:22 PM »

I had to bring this back up to top. Been thinking. Seems if a shooter wanted to do some long range shooting requiring very consistent velocities that it would be achievable with this rifle. Shoot once, pump right back to same pressure, shoot again, repeat. Be like shooting a regulated gun where the shooter is the regulator. Or, a lot like shooting any old school pumper just with a gauge to verify your pumping efforts and a great barrel and trigger with high velocities. This sound right?

CarsonRatSniper · « **Reply #48 on:** October 19, 2014, 11:22:49 PM »

Correct!
Or just tether a 22ci JDS Airman bottle regulated @ 1800 psi to the Foster nipple via remote line for pure shooting (and regulated) enjoyment.

rsterne · « **Reply #49 on:** October 19, 2014, 11:45:08 PM »

My original Millenium Pumper was about 1.16 FPE/CI on the first shot at 1800 psi.... shooting at 40 FPE that works out to 34 CI per shot.... With a 22 CI tank regulated to 1800 psi, there is 1200/14.5 = 83 bar available x 22 = 1820 CI, so you should get about 1820/34 = 53 shots.... let's call it about 50 shots using that setup....

This is definitely interesting, and I'll be following the progress!

CarsonRatSniper · « **Reply #51 on:** October 20, 2014, 12:18:14 AM »

Bob, now you have me daydreaming of an 18 cubic foot 4500 psi Guppy tank regulated to 1800 psi carried in a backpack and tethered to the Millennium...I hunted like that for a few years until I built my Challenger - only it was a 72ci tank with a JDS regulator @ 1400 psi in my backpack and it was tethered to my 35 ft lb 2260.
I still have that rig (its what I took my first grouse with last year) but I scaled down to the JDS 22ci tank to lighten up what I was carrying.

Theoretically *grin* How many shots would a regged Guppy tethered at 1800 psi give?

rsterne · « **Reply #52 on:** October 20, 2014, 12:26:25 AM »

Joe lists the 18 CF 4500 psi tank as having a volume of 118 CI.... With an 1800 psi output regulator it would have 186 bar x 118 = 21972 CI of air available.... 21972 / 34 = 646 shots.... The 90 CI 4500 psi Ninja tank would give 186 x 90 / 34 = 492 shots....

Bob

CarsonRatSniper · « **Reply #53 on:** October 20, 2014, 02:31:39 AM »

Sounds like I need to call Joe tomorrow and ask about a DIN 300 male adapted regulator with a Foster fill nipple...to accept his micro bore hose (of course!).

Are those calcs down to 1800 psi reg pressure or total volume? Either way, that is an *insane* shot count!

*edit* Everywhere I looked shows the Ninja as 'discontinued'

rsterne · « **Reply #54 on:** October 20, 2014, 12:40:49 PM »

Down to 1800 psi.... 4500 psi fill....

I just looked at the Ninja online catalogue, and they still list the 90 CI 4500 and it is available with a custom regulator, set to 1000 to 3000 psi, in either grey or black....It is available as a PCP fill station with valve and braided line for $299.95.... 36" Microbore 6000 psi hose is $40.00.... Also available from Tim @ Mac1 complete with a gauge and angled hose (my choice) for $295....

Bob

CarsonRatSniper · « **Reply #55 on:** October 20, 2014, 01:56:47 PM »

I just got off the phone with John DiStefano of JDS Airman.

He has the 90ci 4500 psi bottles and will set the reg output to 1800 psi. They are $217 (right now - he's currently offering a 20% discount on regs).

If you order his premium fill station adapter it will be $271.
I like this purely to be able to bleed the remote line.

Doesn't B&A make a brass inline bleed valve?

Mike

rsterne · « **Reply #56 on:** October 20, 2014, 01:59:42 PM »

The Ninja fill station also has a bleed valve (Tim's also).... Can you get a Microbore hose from JDS?....

Bob

CarsonRatSniper · « **Reply #57 on:** October 20, 2014, 02:42:47 PM »

I only see braided lines on the JDS site...

I will have to talk to Tim too...since we're using his Extended Steroid Billet lever it would only make sense to have folks order their bottle setup from him if they want one.

I will ask him about making the reg output @ 1800 psi.

*edit* I just got off the phone with Tim @ Mac 1...he can have the Ninja reg set to 1800 psi, offer a longer micro bore hose for backpack tethering and have a slide check installed on the hose by the bottle to bleed the remote line.

UCChris · « **Reply #58 on:** October 20, 2014, 08:34:42 PM »

I would be super interested in a .22 pumper that can get 5 shots at 30 fpe or so (JSB 18.1 @ 875ish fps) Then I can just pump it back up.

I think you have an amazing idea. I want an FX Independence so bad, but $1800 is killer! This pumper idea is perfect for $700.

I can't afford it now, nor do I know when. But if, or when, it is made, I will be saving my pennies!

CarsonRatSniper · « **Reply #59 on:** October 20, 2014, 11:49:15 PM »

$700 was an initial guess that I said not to hold me too...I'm trying my best to make it under $1000.

I'll have a price set in a couple of weeks.

Mike
