.243AI Which powder with 107 SMK?
It looks like powder recommendations for the heavier .243AI are all over the place, from H414 to H4350 to H4831 to R22 to the really heavy magnum powders like R25, H1000 and Retumbo.
Which ONE powder should I start with for this bullet? I dont want to burn up 1/2 the barrel life searching for a good powder. I am running a Shilen 1/8 twist barrel.
