7mm RUM reloading difficulties
So heres the deal...
I just started trying to reload rounds for my 7mm RUM. I ran across this problem of messing up the case when I load the bullet in.
I am using RCBS Dies. I resize the case, the shell will feed fine, but as soon as the bullet goes in, I cant lock the bolt down, or its really hard to do.
This doesn't happen every round but Id say 3/5 times it will.
Now its not the bullets, theyre the right size, and if I take the shell that didn't work, take the bullet out, resize the case, and it will work again.
So my assumption is that when I am pressing the bullet into the case there is enough friction in pressing the bullet that its deforming the case.
So my question is, is there a lubricant for the bullet for cases such as this? Is there something I've missed? I know the neck is clean and deburred, so the friction is the only thing I can find to blame it on, but I have never experienced this before.
Any help is greatly apprectiated!
