Here's how the shroud will tension against the band.

I will have a shrouded rifle assembled Saturday.

Here's the front barrel band - it captures the pivot pin so there's no need for clips. The shrouded models will have E Clips though since the barrel will be fully free floated and will not have a front band.

Any thought to selling the lower as a kit?

CarsonRatSniper · « **Reply #742 on:** October 09, 2015, 09:24:29 PM »

StevenG - Yes, once these are shipped & hunting season is over so I have my machinist back we will start making lower assembly kits...once I have some completed I will offer them for sale.

I shot a couple groups today with the .30 cal.

This is the first 5 shot group @ 25 yards - the one that shot high was the very first shot.

Here's the 50 yard group

I was only using a fixed 4x Bug Buster scope - it shot a 5 shot group @ 50 yards that was right around 1".

Here's the numbers:

First string - all shots tethered to an 1800 psi regulated bottle *No Gauge Manifold* - fill nipple attached directly to the Prod adapter inside the gun so the only volume the gun had is the valve & small space before the check valve (like Bobs Millennium he built).

44.75 grain JSB

774
769
763
763
761

Avg 766 for 58.3 ft lbs

String 2:

766
764
750
754
755

Don't know why I lost a few fps...maybe she's just settling in. I'll get back out to do more shooting when I have time - I'm holed up at home working in guns.

I will be coming out with a .300" Wicked Monster very soon - it should be right around 38-40 grains.

More pics tomorrow on guns built.

Pressure testing a rifle before final assembly.

Mike, They are looking awesome!
I have been going back through the build threads and
the more I read about this rifle the more it amazes me.
I've recently done just a few simple project with a machinist
and the amount of work and time it can take has given me a tiny glimpse of
how much you must have put into this. So I wanted to say thank you,
And thanks to all the behind the scenes people that are helping this happen.

And I'd also like to thank you for letting us all watch with you in the build process,
I've really enjoyed it and have learned from it as well. And I hope to some day own one of your rifles.
Super stoked to see that they are almost done!!

Said all that to say, keep up the good work!

A couple requests/questions,
what is the finished rifles weight?
once you get them completed could you post a recap of all the specs?
(weight, length, mag capacity, trigger weight range, barrel info etc.)

Joseph

Thanks Joseph - These would have been finished a long time ago if I wasn't relying on outside sources for parts.

Here is my 'Poor Mans Barrel Bonding Jig' - a box with holes cut in it stapled to my work bench...it actually worked perfectly

Some of us ... myself for one ... would be willing to purchase the lower-receiver/compression-assembly to mate with an
upper-receiver/barrel of our choice.

X2!!!!!!!!!!!

Mike ... how long is the barrel on this rifle?
That is one good looking pumper!

CarsonRatSniper · « **Reply #749 on:** October 12, 2015, 04:03:34 PM »

The Shrouded Models have a 20" barrel...but there are a couple of full length 25" barrels that are getting full shrouds too.

Sorry if I'm late on asking this question....

But is there a video out there already?

I want to SEE this beast in action!!!

CarsonRatSniper · « **Reply #751 on:** October 12, 2015, 04:44:18 PM »

No, but if I can figure out a way to take video with my phone & upload it to YouTube I will do one this Thursday.

Thanks Mike!

Waiting on ball detent springs to be delivered...they're supposed to be here tomorrow.

***Update***

I spent all morning making some tools so my transfer ports are all exact.

I assembled Millennium #1 with a .30 caliber barrel - it was too late to head to the range so I set my chrony up in my front yard, filled the gun to 2200 psi (its in the red zone but within the range of the Disco gauge) and loaded a 45 grain JSB.
It was *LOUD*!!!

How loud you ask? How about 884.5 fps for 78.3 ft lbs kinda of loud!!! NOT tethered - running as a pure Pumper!!! The gauge shows 1900 psi still in the gun so there's at least 1 more full power shot and a couple of follow ups.
I couldn't keep shooting or the Sheriff will be knocking on my door.

I ran a penetration test in my shop. It is blowing completely through a 1" thick phone book AND a piece of 5/8" plywood.

I am going to the range tomorrow to run numbers on #1 & #7...I need to get Jeremy his rifle ASAP so he can have the Monocores CNC machined for the Shrouds & LDC's.

Stay tuned guys - I have pics & will upload data tomorrow but I'm busy building and playing mad scientist today.

A bit of overfill, but impressive FPE for sure.... Look forward to what you get for velocity when tuned for 2 equal shots in .30 cal....

Bob

CarsonRatSniper · « **Reply #757 on:** October 21, 2015, 11:08:14 PM »

The valve makes the most power @ 2200 psi - I tried that pressure to see what to expect when tethered to one of Tims 2200 psi regged 4500 psi Ninja bottles

I don't know what velocity Jeremy's 20" barreled Millennium in .25 caliber is shooting at but I just did a water bucket test with my 31gr SPH and it expanded to the point if beginning to doughnut hole - I'm guessing low to mid 800's.
Kings blew through 2 pieces of 5/8" plywood and chipped the concrete pavers I had as dead stops.

I swear it can't get light fast enough for some range time!!!

More to come.

Mike

CarsonRatSniper · « **Reply #758 on:** October 21, 2015, 11:11:50 PM »

I forgot to mention...I ended up ditching the tapered springs and used stock Disco valve springs.

I'm also using Century Spring #71152 for a hammer spring - 2" long x .360" OD x .042" wire rated at 10#'s.
The final assembled weight of the hammer & cocking bolt is 104 grams.

Water bucket testing with Jeremy's 20" Millennium.

My 31gr SPH

My 32.8 gr Wicked Monster

These rifles with my slugs are the worst thing small game & critters ever dreamt of!
