Reloading Question

[gunpoorboy1]

This happens to me occasionally:

I loaded 100 each .45LC using Berry's .45LC FP bullets.

After reloading them I gauged them using my Lyman case gauge. 80 of them went in smooth as silk. 20 of them stopped about 3/4's of the way down. Some of them could be forced in but some couldn't. I separated them as I don't like shooting rounds that don't gauge correctly.

Question: all 100 were processed exactly the same---why the different outcomes?

I am not an exspurt at all. I would think that there were double powder loads first if you couldn't push the bullet in any farther.. Break them down and find out.

sizing die get dirty, or moving, check cases for length, could be an issue, which would effect crimp

[samnev]

Did you check the dimension of the case heads with vernier caliper? Could possibly be a swollen case head problem.

The only case gauge you need is the barrel they are going to be shot in. Pull the barrel out of the pistol, drop in the cartridge.

.45 Colt cartridges are known for excessive case head expansion in standard chambers loaded to higher pressures, i.e., Ruger or TC pressure levels. This is why .454 Casull or revolvers re cylindered by Linbaugh or similar can run hotter and still not show pressure signs. Perfect example of this is a Clymer de-leading reamer will not fit Casull cylinders. Make sure your sizing die goes down to fully resize the case and you should not have any problems. Sometimes you need to take some off the base of the die to achieve this, especially with dies designed for use in progressive presses. They usually have a bevel to aide insertion and those silly millimeters show up in stiff chambering.
