Millennium Pumper Production - *The Beginning* - And The Lousy End

[rsterne]

Like any other PCP, if you reduce the hammer strike to decrease the power, eventually you won't be able to fill to 1800 psi while using the full size ports.... However, if you used a stock Disco valve, then you could tune the gun to shoot like a stock Disco starting from 1800 psi down to about 1000.... ie about 20 FPE in .22 cal.... The reservoir is about 1/3 the size of a Disco, so you would be looking at about 1/3 the number of shots (ie about 10, depending on the ES you are happy with).... Other tunes are possible, both in between stock Disco power and a 3 shot "power" tune, but you might have to use a transfer port in between stock and the one Mike is using.... Lower powered tunes (eg. 12 - 15 FPE) are also possible, but just like with a Disco, a smaller transfer port will be required....

Don't think of this gun as an MSP.... Think about it as a PCP with an onboard pump.... that requires tuning like a PCP....

That description is exactly why it has so much appeal to me. 

I think choosing a caliber is going to be the hard part.

to me its easy... sign me up for a .22!!! what we have been waiting for is the evolution of the pumper... and its here!

I'm leaning .22 right now as well for the velocity and shot count as well as pellet availability.   

[CarsonRatSniper]

For me it's .25 caliber due to my slugs and barrel.

Pellets from 25gr to 43gr and Spitzer slugs from 26gr (new - not yet released) up to 45gr.

The .30 is just bad arse, but the 45gr Spitzer puts the .25 right there with it.

That's the whole reason I chose to specialize in the quarterbore caliber - it has the widest range of applications.

I will be on the sidelines watching the magic happen...

[rsterne]

Quarterbore for me, but that .30 cal is calling my name.... *LOL*....

  I guess I could use another .25 cal PCP and having it be unique all the better

[aom22]

For me the Millennium Pumper will be a hunting rifle.
In-the-field, how many shots does a hunter need when taking a varmint/pest or small-game.

At best, one well-placed initial shot.
Hopefully, a follow-up shot won't be needed.
But, a quick full-power follow-up shot is nice to have on-hand.
And, at worst, a third-shot ...coup de grāce.

You know guys, the best thing is to just order one with all 3 barrels - then you can switch calibers to suit your mood (or quarry) that day!

Will it fit a Mrod or Prod?

Mike

What a cost savings that would be 

[UCChris]

If (when) I have the funds for this, .25 for me all the way! I want 3 shots at 45 fpe.

Mike

How would you adjust the power to get the most performance?

[rsterne]

The RVA will allow you to tune the gun within a reasonable range of adjustment.... Each caliber will come with it's own transfer port, sized to suit what is appropriate for the potential.... It is possible a different hammer spring will be required as well, Mike and I will sort that out....

With a 25cc reservoir Bob got 3 shots @ 40 ft lbs...5 shots @ 40 ft lbs *should* be no problem, but we will have to see what the guns do when built.

Mike

That sounds promising. I'd buy a 5 shot; 35fpe MSP in a heartbeat.

I would too if I was 18 and had some money.

What are you saying?

[MEAT]

I love watching ideas become real.

[CarsonRatSniper]

The Challenger RVA will be bored out to accept a 2" long x .360" OD hammer spring. We will have a threaded plug so you can swap springs by removing the plug/tension adjuster.

To go to a lighter spring (factory Disco type) I will have another plug that has an extension to reduce the .365" ID of the RVA so the smaller diameter Disco spring will fit well.

I believe this makes the most sense for an 'on the fly' caliber change.

The first 2 guns we build are going to be 'Millennium Master Hunter' sets with all 3 caliber barrel/bolt/magazine/transfer ports...they will be offered for sale as soon as we gather data and take some pictures.
They may have our Supreme 1.5" OD x 6" long LDC that has an interchangeable monocore to match the appropriate caliber.

Obviously these sets aren't going to be inexpensive but we will be numbering our guns with sequential serial numbers...you just never know! *Grin*

The money is going right back into buying more raw materials for (hopefully) 4 guns...sell those...then build 8 guns...you get the idea.
This is a startup so Jim & I need to sell some guns straight away to build up some capital to reinvest.

Your hard earned dollars would be much appreciated by purchasing a gun if you are able to.

One thing I would like to add about the .25 caliber...

I will have my tooling in about a week for a ~26 grain Spitzer...it is my Wicked Monster Hollowpoint.
It is an *extreme* expansion low ricochet round.

It will have the same exterior dimensions as my 37gr...I'm making my own pure lead jackets, adding a polymer ball inside the jacket and forming the Spitzer nose around it.
You'll be able to see the green ball inside through the HP nose cavity = Certified Zombie rounds! LOL

It should allow 900+ fps on a *mild* tune but will outperform Kings in the BC department...not to mention they'll just about turn inside out when they penetrate!

I will add pics and performance data in my Vendor Gate as soon as some are made up.

My Parents will not let me get another air rifle till I am 18 (I am 16 now). And I need to get a job to earn some money.
