.224 Sierra 95gr SMK Length

Anywhere from 1.28X" to 1.3XX", sometimes within the same box.

I'm done some testing along with a few other F-Class guys in my club. Every one of us had different average lengths. I haven't measured BTO yet though.

I talked to a competitor this weekend who uses the new 110g SMKs in his 6mm and he ran into the same sporadic lengths, so he switched back to 107g SMKs.
 
Maybe consistency in their production will improve over time. The tips are pretty pointy so the OAL's are going to vary more depending on the meplat's condition. As long as the other dimensions (OD, bearing length, ogive shape and location) are consistent then I'd be less concerned with the OAL variation.

I only intend to use these for ± MOA accuracy on steel inside 1000 yards. If they don't buck the wind like I think they should then I'll go to my 7mm.
