Hornady Modifyed Cases

[Balljoint]

Know this was here before BUT looking for the thread size for the Lock & Load modified cases think it's 5/16-36 BUT may be wrong to make my own cases.

Just got mine and had the thread pitch checked we came up with 5/16"-36 also.

Thanks for the info.

Just looked up on my drill size chart, looks like you need to drill out the primer hole with a 19/32" drill for a 5/16" tap

It will be the 36 thread pitch that will be tough to find, I have thought about rethreading the tube piece to something more common like regular 5/16 fine thread which I think is 24, then it would be easier to make my own cases.

Might look at that drill bit chart again, 19/32 might be a little big, lol

These guys have very good prices, but you'd have to buy some more stuff to justify paying for the shipping.

5/16-36 tap $8.50

I have seen the hornady modified case in the bass pro shop. What is the purpose of them?

[geargrinder]

It has a loose neck to insert a bullet into the chamber. A rod enters from the rear pushing the bullet to the lands of the barrel. There is a set screw to fix the rod in place.

Then you take everything out of the rifle and measure. This is the max OAL for that specific bullet.

Correct drill bit size size is 19/64.

remove the bolt from your gun and insert the tool with modified case into the chamber.
you use the push rod in the tool to push the bullet out to the rifling in your barrel. this gives you a max overall length for your gun.

Have to check my drill chart better

I got my tools back when they were "Stony Point" the original maker, and still refer to the reading with friends in e-mails est, as SP numbers, and we all know what were talking about, old habits die hard I guess.
Anyhow, I have both tools the straight and the curved model for semi automatic rifles, and now, thats the only one I use, there equally accurate, but the curved one is much quicker and easier to use, you dont even need to remove the bolt.
So if I were a new guy just buying my first Hornady tool, it would be the curved one. And if your interested in making quality and accurate target ammo, having this tool is a great place to start.
