Your own cases tapped fo the Hornady O.A.L Gauge

[ovenpaa]

I have just drilled and tapped three .308 cases for Dangermouse to check his OAL. Nothing new in this as you can buy a factory .308 case tapped to suit for not much more than a fiver, downside is it is just that, a factory case. DM sent me the proper tap and drill so I could prepare cases that had been previously shot and so fire formed in his rifle and it will be interesting to hear how much if any difference there is when he checks his OAL using his cases.

Anyway DM has told me to hang onto the tap and drill so I can offer a similar service to F-B(UK)'rs. So if you have a fired case or cases you would like drilling and tapping to suit the Stony Point/Hornady OAL gauge please let me know. Christel reckons it will cost around GBP1.33 to post up to half a dozen cases out so that is what it will cost, I would however ask that anyone taking advantage of this service make a small donation to H4H or a similar charity when they get the opportunity.

All you need to do is mail me out the cases in a jiffy bag and stick some stamps in or something to cover the return postage.

Does this sound reasonable?

I think that's a brill idea , it was mentioned the other weekend at the F-class comp.

I'll stick some in a bag and send them over

I reckon it sounds more than reasonable! Going to have to look for some obscure cases for you to have a go at!!! Perfect OAL for a 120 year old rifle..... reckon it would make a difference? :goodjob:

If you can decap them and neck size them and let me know the diameter of the bullet, or even better send me a sample bullet as well I will bore and tap them and then pass a mandrel through the neck so the bullet is a snug fit yet will push through the case with relative ease. Also if possible, send me a couple of each case you want doing, just in case.....

I'm sorry but I've got to ask

What does 'drilling and tapping' do to the case? How does this enable you to check your OAL? What is the 'Stony Point/Hornady OAL gauge ', and why would you want cases to suit it?

I'm not taking the pish...these are genuine questions :? :lol:

There is a very good article on 6mmBR explaining what it is:

One of the very first things I made was my very own OAL gauge, however mine is in a different thread as I did not have the right tap at the time. I find myself frequently using mine to check throat erosion or when testing with a different bullet. I actually prefer mine to the Hornady version as it is longer and easier to use, it is also somewhat more substantial.

Whoa there! I made that mistake with a 6BR case. They need to be as shot not neck sized so that the bullet is free to slide through the neck.

That apart this is a super idea and I'll be bagging some up for you this week.

I have tried both shot and shot/neck sized, I prefer to partially neck size and then open the case neck very slightly with a mandrel to get a snug fit but if the chamber has a reasonably tight neck then an unsized case is fine.

What size drill and tap do you use what size is the tap thread.

Nice one...understand now

That's a very good idea, and a cool tool

Learnt some other terminologies from the acrticle too....
