Determining OAL question

[cornhusker]

Working with some Nosler bullets and got to wondering about this OAL thing..When you but
a bullet in the chamber and push it until it touchs the lands,do you let the bullet just kiss the
lands or jam itin there..I put a bullet in the case and chambered it with a tight bolt closing..And then I
used the Hornady OAL length tool and I got 2 different reading..Which would be the better
method to use.Thanks.for your help on this.I measure to the ogive most times....

Have you tried using the modified case that works in conjunction with the Hornady tool. Even with that you can get slightly different measurements but usually they are very close. Some people take an average of 3 readings or so. Usually when measuring to the thousandths you don't get all the measurements exactly the same when working with distance to the lands.

Do this to find exactly where your lands are. Then you can know exactly how far from or into them you actually are rather than just some arbitrary jam length

When you absolutely, positively, without a doubt have to have it perfect! Way better!

excellent video..

that's all fine and dandy if you happen to have a custom rifle like that one.

But your average run of the mill rifle is not able to function like that..

Why do you say that? I did the same thing with my Remington short action. What am I missing?

HUH???
Please tell us why!

You absolutely can, you just have to remove the firing pin and ejector. If you still feel interference it's because your brass is too large. Bump it back a thousandth more and you'll be golden.

so that explains te risistence..brass a bit to long or is it because it is a savage rifle..and the cocking system is different..?

 

[spife7980]

Well I can't say how a savage feels first hand, you got me there. But I do know that I've heard of people doing it with a bighorn and that has a floating head. I don't see how different it could really be from a savage. Can you chamber a piece of empty sized brass and have the handle fall smoothly?

No way..possible..i think it is do to how the cocking system works

Take out the bolt. FL size a case bumping the shoulder .002". Cut a slit in the neck all the way into the shoulder. Deburr the slit. Now you have a case that holds the bullet securely but still allows it to slide in deeper under resistance from the lands. Seat a bullet long. Push the cartridge into the chamber until it stops. Push the cartridge out of the chamber using a cleaning rod, taking care it falls gently into your hand. Now you have the bullet seated so it touches the lands. Measure the oal.

 

[spife7980]

That ^^ or do the method in the video but seat it shorter until it stops imprinting the lands on a bullet that you have covered in sharpie. Lots of ways to get reasonable numbers. Or mark a cleaning rod with measurement down the barrel to the bolt face and to one with the bullet pushed softly to the lands and then take the difference between the two.
