224 Valkryie build questions

[raventfly]

Hey y'all, putting together a 224 Valkyrie Aero M4E1 build to get into handloading with. Looking at a 18" Bison Armory SPR barrel, anyone have recent experience? I know it's a mostly dead cartridge, but I'm curious and apparently fond of questionable choices. Thanks!

I have a Valkyrie built on an Aero upper with a Faxon barrel. It's an ok shooter. Troublesome to load for and a real pain in the ass.

Personally I'd go 22 ARC and never look back. New build with a Craddock RTR barrel is a stellar performer and runs circles around the Valkyrie. Took it to SD for p-Dogs and was amazed at how well it did in 15-20 MPH winds out to 900 yards.

I’d go with a longer barrel like a 22-24 inches. I have a 24 in bartlin barrel from Croddock shoot like dream. I have a Valkyrie and have no issues getting brass from Starline

Longer barrel for the extra velocity?

I went with a Wilson Combat super Sniper 22" barrel. Zeiss scope and can hit a knat in the ass at 500+ yds. No problem on ammo.

Yes

I went with the Bison Armory 24" 6.5 twist on 224 Valkyrie... first barrel was a Ballistics Advantage barrel 2 to 2.5 inches for 5 shots.
I went with 95 gr SMK, and 80, 88 gr ELDM, mostly. RL 17 was a good powder in mine at the time...fast and accurate.
The 224 Valkyrie was a bit more difficult to get to shoot. Took it apart a few times, then centered the bolt carrier with really helped with this cartridge.

That's sweet. How did you center the bolt carrier? Haven't heard of that before

 

[TACC]

Yes, what was the process for that?

Centering the bolt carrier has been around quite awhile...I learned it in an AR 15 Armours course.
It requires a lathe and a mill, & precision measuring tools.
One of the bolt carrier makers are moving in this direction, but it's only partially complete, leaving still too much clearance, half right is better than nothing.
I have described the proceedure completely on this form several times over.
Here are a couple of pictures, of the proceedure in mill and lathe.
To get and understanding and maybe others will provide these services. It's not super rare...
