Hello All... I probably know the answer to this before I ask, but Does anybody have any data on reloading for the 223 WSSM. Mine will be here in 2 weeks. Thanks.

Too early. Best option is to ask someone here to run a quickload simulation for you.

Winload (the old Powley calculator) suggests 42 gr. of H414 for a 55 gr bullet. No warrantee expressed or implied, start low and work up, etc, etc. HTH, Dutch.

Have you tried the Winchester site?

I just checked out the Winchester Ammunition site and they have data for the WSM's but none posted yet for the WSSM's.

I had tried the winchester site, and was kind of suprised they didn't have anything posted yet...I will call around to the powder manufactures and see what they have to say... will post results.
