On a few of my reloads I have been getting a primer problem. There is a small hole on the shoulder and a tiny crack running down to the base of the shell they meet. I have been using Remington small pistol primers, 4.9 grains of Power Pistol and 40grain V-Max. Is it defective primers? Or is my 4.9 grain too hot? There is no evidence of flattening of the primers.
What is the difference between pistol and rifle primers? Are the rifle primers stronger and should I be using those?

Are you reloading a pistol round??? You didn't say what it was you are reloading.

If you are reloading a rifle cartridge, you should be using rifle primers. More pressure involved with rifle cartridges.

If you are loading a magnum round, make sure you use the magnum primers.

Read some reloading data books.

Sorry, but I thought this was a FN 5.7 forum. I've read more books on reloading than they've got in the library of congress. Do you know the differences in the different primers? I now do. The problem was using pistol primers in a 5.7 pistol round. I've solved it by using small rifle primers.

But thanks for all your help, you are a asset to this forum.

This section of the forum is for info on reloading all ammo, not just 5.7.
