I have a number of Wilson type straight-line seaters and have measured the overall length of the following.
.222 Rem = 96.9mm, Std Wilson
222½ Shilen = 98.0mm, Std Wilson
22 PPC = 92.1mm, Std Wilson
6mm PPC = 96.5mm, Std Wilson
30 BR = 95.9mm, Std Wilson
.257 Roberts = 113.4mm, Std Wilson
6.5x47mm Lapua = 104.3mm, Wilson body with a Sinclair Micro top.
These are all small to medium length cartridges and I would think that longer cartridges, 270 Win, 280 Rem & 30-06 Sprg would have a die length of 115 to 118mm.
