H&H a 285 Speer over 4350 in A-square brass, about 2500 FPS. Just target ammo

Or watch the other guys punching their buttons in the booth taking the test at the same time...

Not that I would ever do that, but I heard a story once of a young Soldier that did...

 

[Wyatt Smith]

They have dividers in the booth. Also after the first fail I was in all by myself for the next two. Three strike and your out. Then I applied for a waiver and found out 3 months later they’re not accepting waivers.
Also I tried to guess and the machine told me not to press the button while there was no tone.

 

[USMA84DAB]

Sounds like you are really trying. If this is what God put on your heart, He will open the right doors.

 

[Wyatt Smith]

Its all up to him.

 

[BeeMaa]

@Wyatt Smith good luck to you.
Hope it works out for you, either way.

Wyatt,
“Persistence is omnipotent “! Not my quote, but it’s true! I went through something similar when I was trying to start my LE career back in the seventies. I kept moving forward and eventually the pieces fell into place. Never give up and keep moving forward! Good luck!

Thanks guys!

Have acquired 212 pieces of properly headstamped brass, dies, chamber gauge, P17 action and stock blank. Fool's errand, here I come...

 

[Wyatt Smith]

It’s gonna be cool

How’d this go?

 

[USMA84DAB]

It is barreled, I have 500 pieces of brass. I am 1/2" from having the action inletted AFTER paying Wenig $300 to inlet a blank! I do not have a climate controlled shop, so that slows things down a great deal. Need to weld up the duck pond - have the plug. Plains game safari in 2021 kinda slowed things down a great deal. About to get back int to he saddle on it though, as the weather warms.

 

[Certus]

Looking forward to it

This is the route I went. Was able to get a nice stock from CZ (when you still could) and a 416 Rigby action, Wiesner drop floorplate (holds 3 down comfortably), express and NECG peep sight. Rifle weighs 10.6lbs. I should note we used two 0.3125"x6" tungsten rods to add 0.57lbs in the butt. It shoulders good.
Gunsmith did not like cutting the rod and more so, drilling those long holes But it beats lead.

Dave Manson reamer drawing.
Almost did one once, did 500 A2 instead.
495 A2 is A-OK.
Art Alphin at his best.

 

[Jefferry404]

That is the reamer my rifle is chamber. Manson and crew are the best...
Mr. Crank,
perhaps you can shed a light. My Jamison brass neck wall thickness is11/1000. But the 495 drawing indicates Art was thinking 16/1000! (not sure why as the 500aa and 470 capstick indicated 12 and 11 thousands respectively!) Wondering if the drawing was misprint and should be 532 neck? OR was Jamison cheaping on his last legs and thinned the brass...Sumbuddy know

 

[Jefferry404]

not exactly a "ghost" shoulder. Once fired, neck sized with 0.530 bushing.

I think the original chamber reamer was done with the idea of shortened 460 WBYMag brass,
so might have gotten into thicker brass at neck when it was properly formed.
I see no problem with that if Jamison made the neck more usual in wall thickness for the purpose-built, properly head-stamped stuff.
0.011" is same neck wall thickness at case mouth as my StarLine .50-90-2.5" brass, fine stuff.
I make my .500 A2 brass from .460 WBYMag. and it has about same 0.011".

Thank much for the insights!
