Head space

[6BRCOLE]

Tony Harper's information should be kept in mind by anyone who is thinking about altering headspace.

I have graduated headspace gauges and checked my rifles, including a V22S and several Anschutz single shot match rifles. None are below .043", with four of them closing on .044". These rifles shoot well with good ammo.

If shooters wish better accuracy performance it is to be found with better ammo not by altering headspace to something other than what TKH describes.

I have 2 factory rifles , 40x and 52d they both have .043 head space .

ArtinNC those gauges are much smaller in diameter in the body than a case is. The length should cause you no problem. I'll respond to your email tomorrow and we will be sure to get you squared away. Thank you

I'll take the gun apart tomorrow and see if I can see what is going on . I though it was the extractors But I striped the bolt still didn't work . Then I'll get back with you . Give me till noon .

You might also contact the manufacturer of the rifle and see what they recommend and will do while it is still under warrantee.

Whidden gun works -----I had the gun in my cleaning vice and for some reason the gauges would not go all the way in the chamber . But I just checked and when I stood the gun on end they dropped right in no problem . This is on a Ruger American 22RF that I'm going to re-barrel . And I just bore scoped the chamber and there is no lead on the rifling , That could be the reason I bad trouble with the gauges ?? Sorry I suggested it was your problem .

You don't want the bolt face or exstractor or ejector to be putting any kind of pressure on the case. If it does you will have fliers.

Don't the extractor groves in the barrel , keep the extractor from putting pressure on the case ? And you don't want the bolt face to case ? You say you need a couple thousand between the case head and the camber ? so .044 should be good ?
