Clearance from Bolt face to barrel face.

[Rtheurer]

What is a good distance to keep from the Barrel Face to the Bolt face? Its a Defiance with no Bolt Nose recess... lug is flush with the bolt face.

Also its on a target rifle.

I set for .007 and plan on about .002 of crush with barrel installed
and torqued to 75 ft. lbs. Has worked very well for me.

I have always done 0.010" clearance between the bolt nose/face and the face of the barrel.

.005" HERE........

I use .010 because there is no reason for it to be any tighter than that. Just a good opportunity for trash to get in and cause bolt closing problems. If you've ever shot around Phoenix with the wind you know what I mean. Here in NC there isn't much of a chance of trash blowing in but the clearance still doesn't hurt.

Depends on what rifle is intended for and the breeching system. As a rule, .005" to .010".

On a side note to this, what do you guys set your headspace to assuming you have .002" of crush. Just barely tight on a go gauge or do you put a piece of scotch tape on the back and try to account for that .002 crush fit?
If that doesnt make sense im sorry still trying to learn.

 

[clowdis]

I try to get it to within .002 by measurement and then double check with go and no-go gauges after assembly. Russ, putting a barrel on without go/no-go gauges? Bet you were using an old piece of brass weren't you?

.010 , close on go gauge, doesnt close on go gauge with blue tape. has always worked well for me.

.010 is where I'm at Russ. Hope all is well.

I also go with a .005 to .010 Clarence. I also check it with plastigage to be sure where it's at.

I have a micrometer head mounted in a sleeve that measures from the shoulder to the headspace gauge that makes it easy to get precise numbers when setting headspace. I headspace to .0015 and end up being able to just feel the gauge when closing the bolt after the barrel it tight. Works pretty well.
