Bullet seating

Registered Users do not see the above ad.


I just started reloading a week ago!
I've got all my brass prepared and am in the process of determining proper bullet seating for my 270 win Ruger bolt action.

1-The reloading books I have (nosler 5th ed) give instructiions on determining the proper seating length by adding a bullet in a fired case. Instructions say the bullet should fall in with very little resistance. Unfortunately, I can't put the bullet in any of my fired cases without the die...

2- I began my height at 3.340 ocl. At that height the bolt won't close on my rifle. THe rifle bolt will begin to close at 3.220. Is this the correct bullet height, or can I still be in my rifling? The factory loads I have to compare have a lenght of 2.180. Both these cartridge lengths seem very far from the SAAMI ocl??

Thanks for the help!

There are alot of methods used to determine what COAL you need for the "On the Lands" length. Once the "on the lands length" is determined you'll need to back off of it a couple thousandths. Try searching and you'll find a load of info on how different people do it.

What I do:

Take the bullet that I want to determine the COAL for (all types of bullets will have a slightly different COAL to be on the lands) and drop it into the chamber. I then lightly tap the bullet into the rifling. After this is done I take a fired case and on the inside of the neck carefully apply JB Weld and place it in the chamber with the neck and bore of the rifle pointed up (this is so that none of the JB Weld falls into the chamber) and close the bolt on the rifle effectivly seating the bullet into the case.

Wait awhile and let the JB Weld set and open the bolt. The Length of the case and bullet is now the COAL seated on the Lands. I've never glued the action shut but I'm not saying it couldn't happen so if you go this route be careful. I watched someone else do it the first time so I would know exactly what I was doing.

You could just resize the neck of a fired case and repeat this procedure without the JB weld but there is always an opportunity for the bullet to slip when you are extracting it giving you a false on the lands COAL.

Good Luck and hope you work up a great load for your gun.
