What's a good neck/shoulder bushing and expander mandrel size combo for the SAC modular sizing die for 6.5cm? Im thinking 286 for the bushing and 262 for the mandrel? I got the 283 (which is technically for 25cm) and 261 for the expander mandrel. I watched and followed Gregs (from primal rights) video on how to determine what bushing and expander mandrel sizes to get and now when sizing my brass the shoulder will bump the 2 thou i want but is only sizing the top 2/3rds of the neck so now I've got to find another combo that works correctly. I set up the die using their YouTube instructional video and i also asked sac if this combo was ok for 6.5cm before getting them and they said yes but obviously it's not working out so well. so now I need some help to find a combo that sizes my cases correctly and effectively. My brass has 13.5 neck wall thickness, which is why I chose 283 to get me about 5 thou squeeze to then open back up with 261 (a little over 3 thou after spring back)
Thanks
