Thanks again, I hope everything works itself out!
Some dies are made that the decapping pin can be removed. If it cant be removed, you can sometimes move the whole rod/expander/de-capper up in the die so it doesn't touch the primer. You would still be able to resize the brass but it wouldn't knock out the primer. I don't recall which dies are what way though?
I usually use a hand de-capper myself, better feel of what's happening IMO.
One other suggestion, not really relevant here if the brass fit before the bullet was seated, but it will still be usefull.
I highly recommend an RCBS Precision Micrometer for setting up your FL Sizing die. It will allow you to just barely bump the shoulder back when you resize. The common directions for adjusting the die don't always fit every rifle, and alot of times; the brass is being oversized or undersized for your chamber. The Precision Mic will remedy this, and serves a few other purposes too. It's not expensive.
