I started to load for 308 the other night. I purchased the Dillon head space gauge (only because everyone else was out of stock on the Lyman's), set up my dies etc. on my 550B and started to adjust the decapping / sizing die (BTW - this is on another tool head as I do this operation seperately). When I load for my 223, I had no problem setting up the die. Cranked it down to the shell plate, backed it out a little, sized a case, checked in in the head space gauge and adjusted everything till it was good to go. My 308 however was a little different.
I set the sizing die into the tool head, raised the ram to the top of the stroke, screwed the die in till it touched the shell plate, backed off half a turn and tightened everything down. Put a case in and sized it. Checked it in the head space gauge and it was too high, so I cranked the die down a little more. Continued to do this till it appeared to be ok. I checked a couple of empty cases in my rifle, and it was slightly difficult to close the bolt. It closed, but not smoothly, so I continued to adjust the die downwards.
I ultimately had the case sized correctly, looked to be perfect in the head space gauge and the bolt closed very smooth. The problem, if it is one, is the die is screwed down about an eighth of a turn past where it was initially screwed down to make contact with the shell plate. I don't remember this happening with the 223's. There's no undue force being placed on the shell plate when I move the ram to the top of the stroke (I removed the case to check this in order to make sure I wasn't going to jam the die into the shell plate) and it feels fine.
I'm just curious if any of you have had to do this when using the Dillon?
thanks for the input......
