I am loading 223 with 55 fmjbtw/c. I resized the brass on a Dillon with a Dillon trimmer and the tool head is secured to the frame. Seating bullets with a RCBS die in a secured tool head ao the same press. Seating to 2.200
The problem is I am still getting OAL variations from 2.16 to 2.30
I know its not from any play in my press. I called RCBS thinking the plug in my die doesnt fit the bullets I am using correctly. The RCBS tech told me this is normal because of the variation of the concentric part of the bullet and the plating.
Than he said something I didnt understand. He said the seating depth will still be same and said something about the "ogive" measurement or something like that. He explained it twice but I still didnt get it.
How can the seating depth be the same if the concentric part of the bullet varries the way it contacts the plug in the seating die? This makes no sense to me at all.
The bullets are mil-spec bulk from wideners. I assume its just low quality bullets, but the Hornandy 55's do the same thing. Am I wrong in expecting to get more accurate consistency in seating? The variations are great enough that I see more exposed cannelure on some loads, than less on others.
The Tech also said the amount of OAL variation I am getting is not enough to cause pressure increases.
These loads are for a 2 day carbine class so precise accuracy is not my concern. But I was concerned if I am loading towards only .3 grains from the max load reccomendation, would the OAL variation cause a dangerous increas in pressure?
