Does anybody have any load data or maybe point me in the right direction to get it for the new 109 gr. Berger bullet in .243 and .243AI ?
Just email Berger, they will email you a copy out of there manual.
Possibly look into info on the Sierra 110. Then reduce and work your way up.
The Hodgdon website has load data for the .243 with the Hornady 108 Gr.Bullets. Check that out...
