My last 300 BLK reloading question was pretty stupid, maybe I can go 2 for 2.
On a whim, I bought a L.E. Wilson headspace gauge in 300 BLK. I took 50 rounds I loaded up with fresh Hornady brass on a set of Lee dies and checked them. All of them sit slightly below the lower step in the gauge (i.e. sitting too far into the chamber). So I tried the new, unsized Hornady brass. Same thing. Then I took one piece of the new brass, resized it (one half turn after the die bottoms out on the shell holder) and checked that. Same thing. I took an old piece of once fired Remington brass and it read properly (between the steps of the gauge). After resizing it, I was back to where I started with the brass sitting below the deck of the gauge.
I dont know of any way to adjust the full length resizing Lee dies other than the 1/4 to 1/2 turn method. Is there a problem with my Lee dies? Am I worrying about something I shouldnt be? Ive never had this problem with a Wilson gauge before on anything else I reload?
In case it matters, Im loading on a Lee turret press. Im only loading 220 SMK's w/1680 for use in my Wilson Combat 16 inch barrel. Shooting it through a MultiMount. I have yet to fire any of these reloaded rounds.
Thanks!
