Hornaday (formerly Stoney Point) OAL modified case?

[Deserthunter]

I found that I didn't have the drill bit, I bought one .............. I went a couple of places in town, didn't find a tap, so I ordered 3 of them on the net.... With the freight they ran about $8/ea... If I find that I don't need the other 2 I'll let someone have them for cost.... They should be here tomorrow.... In the mean time I also ordered a Hornaday 6.5x47L, it arrived today and I've already used it on 2 different bullets........ max length for the Hornaday 129gr SST in my chamber is 2.755" to touch the lands...... A little shorter with a Sierra 120gr BTHP

Smokey262 -- As soon as they come and they are what we need, I'll PM you....

Blue Avenger --- I don't happen to have a lathe..... any idea what I can use to hold the cases so that they aren't damaged?

Smokey 262 -- the taps came in, I'll PM you.... They are the correct size and thread, I tried one of them out.....

I have used a couple small hose clamps. They have enough surface area to grip without crushing the case. I then place them gentley in a vice so the screw heads wedge against the jaws of the vice so the torque of the drill and tap do not spin them. Sorry, don't "splain" things very well.

I'll give it a try with an old case.

I got mine at ENCO tools online a while back. WWW.USE-ENCO.com. model number 891-4932, 5/16-36 HSS HAND PLUG TAP. Cost me 12.21 plus shipping.

I had problems holding the shell without crushing it when drilling it. The bit kept spinning the case instead of drilling.

Smokey262,

Have you figured out how to "hold" a case straight? I was looking for an easier way then hose claps, maybe not....

Hope you get some use out of it....

Only once so far. I tried it with an un-needed case. I trimmed the end so it was square to the head, the placed it upside down on the drillpress table and clamped it with the vise. I made sure that it was square on the table.

I drilled, chamfered, then began tapping. It worked OK but it was not perfect. Then I thought about it some, and came to the conclusion that it is OK if it is off a little bit.

I think the next experiment will be to fixture a case using a pair of split pieces of wood with a hole drilled through the split, and possibly using bedding compound to make it a perfect fit.

So a set up like a barrel vise might just be the answer....... I'll try it.

Tape handles are available at almost any hardware, auto supply, Sears, Lowes, Home Depot and etc. You can also use a "fits all" ( adjustable wrench) or 1/4" wrench as long as you start and keep the tap straight.
