Wrong:
The 300whisper trim to length is 1.355 and 1.365 max. Reference Sierra reloading manual. It's a common error to trim to 1.4 since that is the 221 fireball COL, but that's not what SSK set up the whisper to. I too found the 1.4 information on line, then couldn't figure out why some of my rounds would not chamber. After some more digging around I came across the 1.355 figure. SSK verified that length too.
Hope this helps,
Gos.
