Pretty hard to infringe a Copyright on something that is freely given into the public domain to further the sport.... *grin*....

Brother that is nice. That small detail is a great tribute to Bob no doubt.
One question though: does the term, "ate up with it", sound familiar?

Seriously very nice rifle man.

LOL! Yeah Bill, I have been known to "OVERDO" things from time to time....

Just the way I'm wired, I guess..

I finally got all my parts back from being cerakoted, the engraving colorfilled, and the ALPHA 40 fitted and mocked up before the final assembly..

I attached my barrel to the breech tonight and will let that dry until tomorrow.
I will post more pics tomorrow after the gun is together.

Mike, you and Brent have done some amazing work on that gun, but I have been sitting on the edge of my chair for weeks waiting for performance reports. Sounds like they are coming very soon. Shot my Extreme 408 yesterday and totally love it. All the punch and accuracy a guy would ever want. I totally love your Bob Stern custom bolt. Gotta get me 1 of those.

ALPHA 40 IS DONE!!!!!!

It has been quite a journey. I couldn't be more satisfied with the results! I will post some shooting results as soon as I get a chance. May be a week or so..

Flat out GORGEOUS, Mike !!!

That is one awesome looking rifle there Mike, been watching your build and it's been a awesome trip there Brother.

I had a little free time this afternoon and got to shoot for an hour or so.... Here are a few test groups from the 186gn BBT hp.... The gun was refilled between each shot.... I just wanted to see what type of groups to expect.. I will get into tuning for 3 shots when I have more time...

The results look promising....

KnifeMaker · « **Reply #94 on:** September 05, 2015, 05:39:24 PM »

Looks like a really promising start!

Bet she is a real tack driver once tuned. Have you polished the bore yet? It made a HUGE difference in my TJ .257 barrel.

Lookin' good, Mike !!! .... those BBTs are definitely capable, as you know....

MJP · « **Reply #96 on:** September 06, 2015, 01:15:47 AM »

The rifle looks great, and seems to group ok on 50yds. Waiting to see how it does further out. Nice job on the gun!

That's a heck of a start Mike. That is where a lot of people get all happy and tingly on the inside. Based on what you have displayed thus far, you aren't likely satisfied. For a hunter, it will work on anything with a 5" KZ and allow some fudge factor. What kind of FPS/FPE are you developing with that boolit?

Rizen 1 · « **Reply #98 on:** September 06, 2015, 06:58:35 PM »

Bill, with the 177 gn BBT Chris was getting around 1000 fps on a 4500 psi fill with century spring #72056. (With Brent's heavy spring that number would obviously go up.) That is around 390 fpe with that bullet. The 186 gn BBT would be a little higher but similar... I am pretty sure I can get to 1250 fps on helium with the 186, and that would put me at 645 fpe.... Not bad for a 40 cal....

Almost double the energy delivered by a .45 ACP or 9mm handgun, using helium and right on using air ...... Nice!
