This is off subject but do any of you 356TSW fans know if there are published SAAMI specs for the 356TSW. I went to SAAMI but didn't see any, perhaps as the caliber has been unfortunately discontinued. Great deal on the 3566, my daily driver is SN TSW0660 with a Scott Sullivan 9mm barrel.
Dan,
I've been using the following load on all my .356's with excellent results since I bought my first one in 94.
Federal or Starline brass.
Primer Winchester WSP
Powder: Accurate #5 - 6.9 Gr.
Bullet: 147 Gr. Remington FP Match
I have noticed the Starline brass doesn't appear to be the same...
