I load a good number of coated bullets over Trail Boss in .41 Mag. Like the loads I have for .41 mag a lot. Now I am loading 158 grain coated over Trail Boss in .357. My questions are: Best accuracy with magnum or regular primers? The Hodgdon data I use is for magnum primers. Best accuracy towards the lower or upper end of the data range?
My inclination is to go ahead and use the magnum primers (I have a fair supply of them) and to load near the top of the powder range (not touching the bullet base).
Would I expect better accuracy with HP 38, Universal, Tightgroup, or Clays? All of which I have a little of. Not much HP38 though.
