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

[grand-galop]

They're spoken for but not paid for yet...I know #1 will come through (you know who you are LOL).

Regardless of serial #, these will be simply awesome rifles!

 

Mike

Hey Mike!! Can you send me an E-mail on the first 2 rifles??? I might have found some funds hidden for a long time in case of EMERGENCY....   LOL

Doug - I wanted to o ring the barrels at the transfer port to do just that but the variation in port size from .22 to .30 cal is too drastic - the Delrin transfer ports will be a standardized length though with the appropriate port size for caliber...that way the port coming off the valve face is the correct size so we don't end up with a larger chamber than the port hole in the barrel and lose pressure.

The barrels will index off of the face of the breech...no worries about thread wear.

I have PICS!!! I'm getting them uploaded now...

Here's one next to my standard Picatinney 22xx/Discovery breech



I hope you guys like these so far...still have a way to go but they're 'roughed in'.

Very nice!Thanks for the pics looking forward to more
I count ten breeches there
I'm very excited to see how these turn out!

Now there's some eye candy.  They say a watched pot doesn't boil but I'm watching this thing like a hawk.

[CarsonRatSniper]

Yep...there's 10

I have 6 barrels - but I can't afford 10 stocks right now. I may just build 10 guns and have 2 stocked...we'll see how it goes.

You still have transfer port but the barrel screws on and stops before it.  Transfer port is in the breech.

Oooooo..

Same here. Thanks for posting the progress pics.

Ok Mike I have a question:
Is moisture a real problem with pumpers?
If so...
Is there any way to add a small moisture filter to the gun?
Would you have to tear it down every so often to
get the moisture out?
How hard would a complete tear down be?
Thanks for any help.

Moisture doesn't seem to be a significant issue with pump and dump MSPs.... possibly because the only reservoir they really have is inside the valve.... I have heard some reports of moisture problems with the FX Independence, one of which was related to the use of a piece of cheap, plated threaded rod for the piston rod which flaked and rusted (and that isn't inside the reservoir).... but that is complete heresay.... I don't think there should be any more problem with the Millennium Pumper than with a Disco which is filled with the stock Stirrup Pump.... The best way to prevent moisture buildup in any PCP is to fill from a tank as the air actually dries (ends up with a lower relative humidity) as it expands into the gun.... Any moisture ends up collecting in the tank instead of the gun....

Yeah what farmerjoe said, is moisture going to be a problem when pumping this gun?

Bob

What if we dont plan on getting a tank for the gun?

[rsterne]

I repeat....

I don't think there should be any more problem with the Millennium Pumper than with a Disco which is filled with the stock Stirrup Pump....

Pumping is pumping.... refilling from 1000 to 1800 would feed the same amount of moisture to either gun, and the stock Disco pump has no moisture trap....

Here is another discussion on the topic it starts towards the bottom of page 1

Of course just remembered this thread....after I just bought a new rifle!!!!

Would be cool to have one rifle to do it all.

[UCChris]

I want one in .22

5 shots at 33 fpe (18.1 gr @ 900) would be perfect for me. Assuming you don't have to pump more than 50ish times to "refill"

[rsterne]

I would think your shot/FPE combination is within the realms of possibility with the larger reservoir.... The .25 cal took 40 pumps for 3 shots of 40 FPE (total of 120 FPE), so that should be roughly 55 pumps to replace (5 x 33) = 165 FPE.... just an estimate of course....

Bob

[UCChris]

Hmmm, the pennies will have to be saved!

[Nomadic Pirate]

So,....what FPE would be possible in .25 if you had 2 shots ?

Me, I would be looking for maximum FPE with one shot as a back up.
