Im using Lapua 221 brass Trev but i saw the trimmed case length of "missed" at 1.399" . Most of the lapua's in a box will be 1.395" with a few longer and a few shorter.

Thanks missed,
So you size a 223 case in the 221 form die then size again in a 20VT die, yes? What advantage is there in forming a 20VT case from a 223 case?

What is the die your using to size from 223 down to 20VT, the one in your press with the hacksaw (Photo)

Try Federal gold match 205GM primers. I use 26.8gn of 2206H in my 204 tikka without that primer problem using 205GM primers.
