Stoney Point OAL Gauge

OAL tool

Hi Supercub,I use mine all the time,and it works well!Rather than send cases to the States for modifying(.280AI),I had my gunsmith thread a once-fired case for the tool.No problems!I'll be by the new WS in Kamloops BC on Thursday,I'll see if they have one in stock!Regards,Mur

Do they thread the flash hole for positioning on the tool?

Yes, they thread the primer flash hole for the right thread. Wholesale in Calgary had one this weekend, but they have very little stock of cases. I bought a bunch from Cabela's by mail order, they were on for half price. Check them out.

I modify my own cases....you need a 5/16-36 threads per inch tap which you can buy at KBC Tools. Just full length resize your case, inside neck ream it and then drill and tap the primer pocket.

I was able to find one here in Canada. The fellow selling them recomended using once fired (not resized) brass and threading them to the thread size you mention. The theory was that the neck would hold a bullet but still allow the bullet to move forward to the max OAL.

I have know idea either way as I have never used this tool, but does it make a difference?

oal gauge

I find it works well on long throated rifles, especially milsurps. Using heavy bullets in k98's you can easily acquire the "sweet spot" off of the rifle's lands. Commercial oal is far too short for getting the best accuracy out of these rifles.
 
It might make a difference using a once-fired case, as you're really measuring from the shoulder (where it headspaces) to the lands. If the Stoney point case isn't the same length as yours from shoulder to base, there will be a difference.

As far as neck sizing goes, you need to be able to move the bullet easily within the case. Otherwise you won't be able to tell when the bullet contacts the lands.

I did check out Cabelas and all they had left was the curved ones for levers and semis. :(

#1, Eric is correct, if you want to get an accurate measurement you need to use a case fired in your individual rifle, the factory cases stoney uses are undersized to fit in any chamber so in most cases the reading you get with them is actually shorter, up to .010 short or more in some chambers.
 
Just build your own gauge. I made some up on the lathe, I drill and tap my own cases so no need to spend big bucks on cases. ;)

Now you tell us! :rolleyes:

Why not make some up and sell a few on the EE? :)
 
They are abit time consuming but have thought of it before ;) It takes time too prep the cases as well but works very well. I built one for RR and he said you couldn`t pry it out of his cold dead hands now..LOL
 
Just got my Hornady Lock-n-load gauge and modified case from Cabela's today (USPS/CP and no GST or brokerage charge!). Works like a charm. Makes measuring so much easier.

The overall length of the case is good, but as stated the shoulder is marginally shorter (eye balled it only). The instructions state that it may be off by a few thousands, and if concerned to use a headspace gauge on the modified case and on your once fired case, and to factor in the difference.

I bought mine last year at EPP's.(ON) They usually have then stocked.

Epps had old stock they bought when it was owned by Stoney Point, they wanted $40 for the gauge alone and they did not have the modified catridge. Cabela's had the gauge on for $26, the cartridge $5. So shipping (which I would have had to pay for the modified cartidge anyways) and tax come to $48.77. Seemed pretty even to me.
