Re: Modified case

I have a Stoney Point and it is 5/16-36 as well.
I bought a tap from MSC several years ago and it has served me well. Seems a little pricey but it does not take long to pay for itself.

I have one you can borrow if making one doesn't work out.

you are correct, and I stand corrected. I checked the tool the other night. Where I got the 5/16-27TPI in my head I don't know. Still the extra fine thread for a .312" diameter is 32tpi, so that doesn't make much sense as well. They should have made it M8-32tpi, which is the standard Timken bearing nut thread. 8mm is .315" diameter, and 32 threads per inch is standard. Next one finer is 40tpi, and that's used on the 5/16" diameter. 36 TPI just doesn't make much sense at all, and it just slightly short of the standard 1.0 metric thread. surprised that somebody like Redding hasn't jumped on this one.

I think they do that so its harder to make yourself so you'll have to buy theirs.

or send me 2 fired cases and I will make them for you.

Is this offer open to anyone???

Take a once fired case (unsized) and see if the bullet will slide into it freely. If not the .311" reamer will work. The threaded hole is another, but not that hard to take care of. You could single point the thread if you have a lathe and are good at grinding high speed tool bits

I think the 5/16-27 is the thread used on shotgun cleaning brushes/patches etc.
