Suppressed 22 BR build

[Yoteski]

Planning on building a 22 BR as a dual role gun; mainly predator rifle and backup match rifle. The caliber is really intriguing me. Couple questions, how short of a barrel can I go to run my can, yet still maintain good velocity? Also, what twist should I be looking at to run the new 88 eld?
Any experience/insight with the caliber would also be welcome. Thanks guys!

I have a 22 inch 22 BR barrel on my Bighorn T3 and am very happy. I am using a Thunderbeast Ultra 7 6.5 can.

I would get a 8 twist so you can run pretty much anything up to 80-82 gns.

Be sure your gunsmith uses a reamer comparable with what you want. I said I wanted a no-turn neck chamber and I didn't want to trim back my brass. I have to do both. Its a one time pain in the ass, but it is still a pain.

What velocity you seeing with the 22"?

I have a 1-7" in the works.

21" and I figure I should be around 2,950-3,000 fps with the 88's.

I think the 22br is gonna be a real sweet spot for the 88's

At 2,950 it's got my 22" Dasher (2,850 w 108 elds) beat by a small margin on paper fwiw

In process of building a 16.5"(as of now) 22br for the same general idea as you. Have the Brux 1-8 ordered, Borden Mountaineer with a trigger tech, got to decode on bottom metal and stock. Stock???

 

[Dai Bando]

1-8" is a mistake worth fixing.

What would you figure for barrel life taking it easy on a 22 br?

30-ish grains of powder...2500 accurate rounds?

 

[Dai Bando]

2,500 is as good a guess as any.

 

[bogey]

why on the 1-8?

 

[Dai Bando]

Twist matters.

Bullets aint getting shorter

I would agree if your going to shoot the 88 eld a 1-7 twist is the way to go. A 1-7.5 twist might work but a 1-8 twist would be marginal at best.

Rule of thumb, always go more twist with shorter barrels since velocity will be lower.
