Primers

Ronvandyn:
So, I am finally getting together all the things needed to begin reloading my own cases.  I also have the Reloaders Bible, but there is one thing that the book is not real clear about.  Primer sizes. 

It?s pretty clear about don?t use magnum primers for regular calibers without some serious thought, but it does not seem to address which primer is normal for which caliber.  What I mean is, does 40S&W use Large Pistol Primers or small?  How about .45ACP?  Is it case dependant, or caliber dependant? 

Since I am eventually going to be reloading 40S&W, 45ACP, and 380ACP(with some .38spcl and 357mag mixed in) I figure I?ll have to have a pretty wide selection, but which to use on which is the question.  Any insight from you old hands would be appreciated.

Bigtony:
45 ACP is large primer.  40 S&W, 380, and 38spl are small primer.  357 mag can use small or small magnum primers.  I don't have the Reloaders Bible but if you purchase a good load book most load recipes have what primer is used.  Also make sure you buy pistol primers for pistol and rifle primers for rifle.

Dan W:
There is some .45 Win NT (I think) brass that uses the small primer, just a heads up.

You should be able to identify the primers easily (large or small) just by looking at the base of the brass. If you can't tell , a caliper measurement certainly will.

Magnum or standard primer brisance( how hot the primer ignites) is recipe dependent, usually based on the powder type.

Tony is correct that the load data will tell you what you need.

There is another type of mil spec primer that is used for M16's M4's & AR15's that have a harder cup to prevent slam fires. Some use em, some don't

Ronvandyn:
Thanks guys.

Now for another question.  I have spent the last 2 hours trying to find a good price on bulk bullets.  Nothing fancy, just good range bullets for my 40 S&W.  And while I have been able to find .40 bullets in vast quantites, very few are just the old standard RNFMJ or FNFMJ projectiles.  Any suggestions on where to go for these?

They're not jacketed, but they are reasonably priced at about $30/500.

They adjust the hardness of the bullet to the application so you can use plain lead bullets even at magnum velocities.
