Rem 722 Rebarrel to 300 Blackout

[Slughammer]

I had one spot that was lagging behind. I ended up doing 5 cycles to get that area caught up. It's not perfect, but it's pretty good.

It looks very nice. I can’t wait to hold it and try to find what you call a bad spot.

That looks really good!

Bring it to Ridgway for the annual cast bullet match June 8-9, range will be open for practice on the 7th. We shoot silhouettes 200-500m.

The 300BO has made its way to the firing line in both boltguns and AR platform in years past, and tied for HOA in 2019(?) against a Tom Gray built Rem 722 in 35 Remington and a Rem 700 in 30-06. That was a 16" 8 twist AR with 4x scope!

I got to see the rifle on Sunday. I have to say it is beautiful work. Slughammer did a great job.

Oh to be 30 yrs younger and afford to have/learn to be a machinist.

I had John Taylor do for me a Remington 722 in 7.62x25 threaded for can. Very pleased.

My remington 700 had a spacer block in the magwell because of the short cartridge of the 223 round. Maybe it would help you. It was like a 1/4" piece of black plastic stuck in the back side of the magwell. I really like what you did here.

For my 7.62x25 John Taylor used a benchrest loading tray to fill the mag well. Just drop a loose round on the platform, close the bolt and it gobbles it up. Plugged the plunger ejector hole so I can pick fired cases off the boldface instead of chasing through the grass for empties.

Barrel is 4-groove, government form in 1:10" twist with same throat as .30-'06 so I can seat out 174-grain M72 or M118 Match pulls with a case full of 4895 pull-down for 1080 fps. Ordinary Combloc PS ball gets 2000 fps.
