Drill bit and tap

Does anyone know what size the drill and tap is that's used to make our own modified cases for the Hornady Lock & Load device ?

 

Bill this may not help you but I think they have a adaptor for the Hornady. I have their whole set up and make my own modified cases. You can find their tools here. http://www.deadcentersports.com/index.html Sorry they don't have the adaptor but maybe they might make you a jig to work with your Hornady good guy to work with.

 

Thanks Bro. I've seen the kit online in the past but cannot seem to find it anywhere online now.

I found it I think 5/16" 36 tap and a 19/64" bit. http://forums.outdoorsdirectory.com/showthread.php/138593-DIY-Hornady-COAL-gauge-modified-cases

WOW Thanks guys for all the info. I appreciate it.

 

I just bought a tap and bit in a kit on amazon a few weeks ago...

5/16" - 36 HSS Right hand Thread Tap with 7.3mm Drill bit

 

I have the same set as gman and works well. Try and keep everything as level and plumb as possible or you will end up having a modified wobble case which can brake the threaded portion off your hornady tool. Don't ask how I no this...LOL

 

+1 on Muleman-----if off centered and wobbles it WILLL eventually fatigue the aluminum threaded part and snap off.
Another "Don't ask me how I know"

 

I wouldn't rush out and buy a mini lathe for this but it makes this task a five minute job. Mini lathe also very handy for neck turning brass. Still trim with my Lyman trimmer.

 

Here is the die and drill on Amazon for $19.99. This is where I got mine.

I have done a couple on a lathe, I use a resizing die to hold the case. If you have a drill press you can just push the brass into the die then clamp the die in a drill vice to hold it vertically while you drill and tap.

 

Single point in lathe. Good practice if you are new to a lathe.

 

Wilson trimmer bushings make this very easy work in lathe or drill press. Don't try to chuck brass directly in lathe, it will distort it so it won't easily go in chamber. What size cases are you working with? If they are small, you might want to investigate using the Hornet adapter setup which uses 12-32UNEF tap.

 

Mini lathe would be very handy for this.Like to find me one some day. I would gladly by the cases but can't find them in all calibers.

 

Never thought about using the Wilson bushing(great idea). So I guess there is no problem with case spinning in bushing? Thanks for the good info.

 

The 19/64" drill will work OK for most cases. But those cases with .378 Dia.(223 204,etc) will have trouble. 19/64" is bigger than the correct number drill and the base rim will split off.

 

You want a drill bit in the range of 0.2820 - 0.2890" for the 5/16-36 tap. The drill that comes with the set above is 0.287" (7.3MM).
