Do you think that in the .38 caliber there would be an accuracy difference between the Magma 150 grain FP-FB vs. the 158 gr. FP-BB? I want the 158 gr., but I wonder about the bevel base. Saeco makes a 158 gr. TC Flat Base, but from what I've read and my buddy's experience with them, I don't know that I want to take a chance, if there would be something wrong with the mould.
