I got a Remmy with a Hart 1/9 twist 243AI. I've been shooting 90gr. Bergers and want to try some 105's. My main powder has been H-4350. Am I good to go with my powder or is there something better that I might use. I would really appreciate your thoughts and suggestions. The 90's are very accurate, but like to get the 105's working for some long range shooting.
