got a round that wouldn't load. Meaning the neck was to big and I had to do surgery to get it out. Without shooting it. Is this round to hard to reload?

I'd make sure that the brass is properly trimmed to length (check the manual) and I guess in theory, if the COAL is too long, you could jam the slug hard enough into the throat to get it stuck too. Don't do that.

Make sure you are using enough lube when resizing.

Was having same problem you speak of. Basically after running the brass up into the die, backing out was stretching the brass giving me the same issue you speak of.
Started using more case lube in neck and the problem went away.

Ok, your just lubbing the outside only right? Getting it heavier on the neck and shoulder?

You should lightly lube the inside of the case mouth, as well as the outside of the case.
Most lubes then need to be removed.
After sizing, check the length of the brass to see if it needs trimmed.

The body of the case gets lube and the inside of neck.
Don't get lube on the outside of neck or shoulder as this will cause brass to crush due to the hydraulic effect.
Very rarely do I have to trim .300 wsm.
