Stoney Point Head 'N Shoulders Gauge

[7.62X51]

G'day All,

I've been using my Stoney Point Head 'N Shoulders Gauge to check my die
adjustment on all the varieties of cartridge I reload for, 308W, 223Rem, etc.
Now I'm reloading the 6 Dasher and this case is not on the Bushing Size Chart.
I'm assuming the one to use is the .350" bushing, as used on 6PPC, 6BR, 22BR etc.
but none of them use the 40 degree case shoulder. Does the shoulder angle change things
bushing wise?

tnx,
Chris

I don't think it really matters which size you use as long as you use the same one each time. it will still tell you how much you are pushing the shoulder back.

If you can have your smith make a gage out of a 1 inch barrel stub. Just have him run the reamer in tell it cuts to the shoulder. and you have a gage for checking seating depth also.

No matter what insert you use on your case, all you're after is the "before and after" measurements. Shoulder angle won't make any difference. Use the same insert before and after.

I use the .350 for my Dasher brass.

I believe you are correct!

I have a 6BR. I am getting a lot of strange numbers and scatter using my Stoney Point gauge. Any tips on whats wrong. It's a case fired in my rifle. I think the case is a tight fit in the chamber and it doesn't get inserted to the same depth each time???

webster
are you talking about your seating deapth. Or bumping your shoulders on your fired cases?

I am trying to determine when the bullet is touching the rifling lands. I don't think the case is inserted to the same depth in the chamber each time. I have to push pretty hard to get the case as far forward as it wants to go. I am getting as much as 0.080" variation with repeated tries.

If you have a resizing die with neck bushings in it you could just remove the bushing and resize the case.

I have never had that good of luck using a the hornady tool my self could be me! All I do this day's is use a fired case that chambers really nice and put just a little crush on the case neck. Just a nuff to hold a bullet with a little Resistance and seat it long and chamber it in the rifle and then remove it very carfully and measure it. Do it a couple of times to check the measurement.

Its not uncommon to have to tweak the case a little for a good fit. Especially in custom tight chambers.A tight neck is the first place to look. Cases must fit easily/loose and still easily release the bullet before you will begin to see accurate measurments.
The Hornady quqge is meant to be used with NO force. Modify it never force it.
