I just need to know if this looks right...sorry for the pic, I tried like 10 times to get a clear pic.

FC brass on top (not crimped), decrimped in middle, and last one is decrimped with primer inserted. Used a RCBS tool in a drill to do it.



Primer went in fine. Inside diameter of decrimped rounds is .175, inside of crimped rounds is .170.

Hope this helps and hope you can tell me it looks good, I have 3,000 crimped brass sitting waiting for some tender loving care.

Way too excessive, and  you just lost some case life with that.  If you ream it right, you should barely be able to see the shiny brass where you removed the crimp.  If you are limited to using that tool, I suggest using it by hand and go lighty....very, very lightly.  That drill press is going to kill your brass.

ETA:  When using your chamfering tool, a few twists should do it.  I suggest buying one of the inexpensive Hornady hand tools, or the Lyman hand tool....the Hornady would be easy to chuck into the drill press, and would minmize damage due to the design.

Thank you, I thought it might be a bit excessive. Basically the way I now understand it is that you need to round the edges of the crimp to allow easier insertion of the primer instead of digging out the crimp with whatever tool you have.

No problem!   Also, you are correct, the goal is to remove just enough to slip the primer in.

I use a Lee champher tool by hand to break the edge and then use a primer pocket reamer by hand. The key words are BY HAND. Or get a Dillon primer pocket swage ($95.00) That's IMHO.

+1 on the Hornday tool, it's so popular it's back ordered very often.

Hornady is good to good.  I picked one up from Grafs since I have switched to surplus brass and it has worked perfect for large and small primer pockets.  Get the combo tool package... save a few bucks.  Just wish the handle was bigger.

Pricey, but well worth it!  






That is all.

The material displaced by the crimp ring is just couple of thousandths of an inch.  Use the trimmer to make just the thinnest bright band at the edge of the primer pocket.

If you don't have a 6 inch machinist's scale get one.  Look at the divisions for 0.010 inches; if the chamfer you added is that wide, that's too wide.  You could also use your calipers to estimate the width of two or three thousandths.  Open the jaws that far, then look through the gap with a light on the other side.

The chamfer tool can work, but it puts an edge on the pocket that makes for non smooth primer seating. I have the Super-Swage and it works well, but you can booger up some brass with it, I boogered up several hundred once fired LC '07   If you get it adjust it slowly

I use the RCBS swaging die.  This thing is a God send.  Super easy and fast as well as adjustable.
