Rifle brass sizing

[jwfire25]

So I have a batch of 15 cases that won't size down enough to go into the rifle without resistance. The shell holder is touching the die. What would cause this? I have fired none resized brass that measures 1.626. And this problem brass after resizing measures 1.630. Its only been shot twice and I only used 41 grains of Varget.

I'm so disappointed that our resident developmentally disabled reloader hasn't chimed in.

Is that with the case in the die? Raise the ram to re-size another case and look to see if there is a slight gap between the die and shell holder. Under the pressure of re-sizing there will be stretching of the press/frame which creates a .004" gap. Bring the ram down and screw in the die another 1/16th of a turn. Test again with another fired/lubed case.

What lube & how much are you using on those cases?

Crappy dies is usually what causes it. What die set are you using?

I had a set of RCBS standard dies that I kept chasing my tail on trying to bump size my brass correctly. I was having the same issue you are over and over. If I didn't over size the brass, the die wouldn't work. Then I'd have case/head seperation after about 3-4 firings. I switched to Forster dies and haven't had an issue since. And yes I consider RCBS standard dies crappy dies for the purpose of what your doing.

The only other thing could be if your running one brand of shell holder with another brand die. I know that has caused issues for some people in the past, although I've never had that issue myself.

To add to this as well, any signs of hydrualic denting on your case shoulders?

You can grind a few thousands off the top of your shell holder. Put it in a bench grinder or put it face down against 220 grit sandpaper on a hard flat surface, and move the shellholder in a figure 8 pattern.

Try Imperial sizing wax

All my equipment is hornady. Press and the custom dies. I am using one shot lube. I dont use very much because I have crushed brass before.

Your loading .308 right? I have a set of Redding competition shell holders that I don't use. If you want to give them a shot, I'll send em to you for a low low price. They have different thicknesses on each holder. allowing you to adjust how much bump you get on the brass.

Seems like your FL die is not properly set-up.

Check this out, look for the FL die set-up instructions - https://www.hornady.com/support/user-manuals#!/

Also, for FL sizing, use Imperial Sizing Wax.

I just noticed his numbers. Isn't it odd that his fired brass is smaller than the SAAMI minimum Go Gauge? Still, dies should bring it down to 1.627" approximately.
