Origin->Hawk Hill->Grayboe.... Go!

[Shootin25]

Building rifle number two for this year.

Specs:
Orgin Action
Hawk Hill 7.5 twist 26” .820 muzzle in 6 Creed (str8 taper)
Area 419 brake
Triggertech Special str8
Grayboe ridgeback Duracoated Flat Black
Devcon bedding
MPA bottom metal
Area 419 Arca Rail (all my stuff runs Arca)
Leupold MK4 Rings (steel)
Leupold LRP FFP 6.5-20
Alpha Munitions brass
115 DTAC’s
H4350
BR4 primers
NSS assembly tools
Forster go/no go

That’s the plan. Most of the parts have been received.
Dropped off misc parts at OC Custom Coatings for a coat of Shockwave Blue.

Will be used for local fun stuff.


Will post as it comes together.

What distances will you be shooting?

Curious about the scope choice, do you have experience with it.

[Shootin25]

Max distances will be right around 1000.

Only experience I have with an LRP was 5 shots taken with a 308 to 600 at ASR.
A fellow shooter allowed me to try it as I was curious. Seemed par with the others in that price range. What I liked was the simplicity, along with the elevation turret. Eyebox was not that of the scopes in the 2k+ bracket, but again, it’s also less than half the cost.

Cerakoted items installed on the Duracoated Flat Black Grayboe.
All parts in hand and ready for final assembly.

Using that new negative muzzle rise configuration, eh? Where does the scope mount?

[TKCastle]

Nice. Want to build a ORIGIN action. Are you using invisi-nut or 12 point?

Also, what was the lead time on the ridgeback?

Bolt manipulation is night and day difference after tuning service.

Thanks Randall!

Just checking in on updates on your build. I have a origin action on order and looking to possibly go 6 creed as well and was looking at hawk hill 7.5 twist so seeing how it's shooting.
I am looking to probably use the ARC barloc system since my nucleus action is running that system.

Thanks chad

This thing shoots lasers! Have only been shooting 115 DTACS w/h4350 so cant speak for other bullets or powder.

Bolt is butter smooth, no issues to date (600+ dry fires and 240 live). Shot my first match last month, had a blast!

Barrel sped up around the 100-120 count, and I have yet to check FPS again since initial development, but it was at 2930 with 40.3 of the 4350. I’ve taken it up to 41.5 and stopped there as it started to exhibit pressure sings.

Overall, it’s much more accurate than I am. Barrel was beyond easy to clean, and shoots in the same place every time I take it out of the case. I’m not too picky when it’s comes to SD/ES numbers. My junk shoots where it should, and I have much more obvious areas I can improve (positional shooting, time management, etc.). That said, ES is high teens, but it may have changed.

Building another in March chambered for 224V.
