Resizing 6.5 Creedmoor to 6.5x47L

[bsekf]

I acquired a few 6.5 Creed cases and tried to resize in my 6.5L full length die. I am getting dimples in the shoulder. Do I have to trim before sizing? I was going to do it after. I did not anneal, they are once fired.

you probably aren't going to get good results trying to push a 30° shoulder back .090" in one step..

Got it, need to find something with a 40 degree, push it back till it chambers, trim and then fireform to blow the shoulder out. Probably not worth the effort!

Since they're once fired, I'd anneal them first & try a couple.

The dimples will blow out......

Look at the picture of the case in the press.

Case shoulder push back

How far is it feasible to push a shoulder back on a case? Say for instance, I wanted to do a long-neck .284? @Fuj have you jacked with anything like this?

This is how you move a shoulder back. You can reduce the case diameter about .050" per step. So you would need to size your cases in three steps.
