headspace

[crystalgayleguy]

how many thousandths is too much headspace

 

[ARlife4me]

More than .006"

 

[ARlife4me]

Maybe?

.000-.003 is the general safe area.
How much do you have?

I took a 223 wssm barrel off a model 70 put a 243 wssm barrel on loaded a new brass 35 grs varget with a 100 gr bullet fired it and the gunsmith who put the barrel on measured the new brass and then the fired brass and he said 8 thousandths the fired brass looked good

I try and shoot for .002

For many (and I'd have to go to the SAAMI web site to check the WSSMs) there is 0.010 between GO and FIELD. Be best to check with gauges. Measuring brass is just "maybe". Gauges don't lie or fool ya'.

[crystalgayleguy]

looks good

If your patient with readings and setup, this don't work to bad at all for gauging headspace measurements.

 

[243winxb]

.010" + possible case separations.

I am thinking the SAAMI drawings usually show 0.010"

SAAMI website should have specs. I believe it was .010" for 25-06 between go & no go. I had a 25-06 with .012" from the factory. I'm going to guess that there's a large percentage of factory rifles on the fat side of headspace. I have a custom with around .006" and it shoots bugholes.

Just came from the SAAMI web site (www.saami.org). Their drawing shows 1.2403 min. and 1.2503 max. for the Win. 243WSSM. That
s "GO" to "FIELD". Exceeding "FIELD" invites dangers conditions. Me? If I had "GO" + .008, I'd set it back a few thou. Say, "GO" + no more than .005",, preferably GO + .002-.003".
