I am a newbie to reloading so please do not laugh. I am going to reload for a 45 auto and a 380 auto. I plan on using Winchester primers. Large pistol for the 45 Auto? Small pistol for the 380 Auto? mttrapper[:)]

  I have reloaded for many years without ever using magnum primers. I guess I would use them if I had them, but really don't see the need.

  Easy one. Magnum primers in magnum cases. I.E. 264 magnum, 7mm Rem magnum, 300 Winchester magnum, 338 Win mag, 458 magnum. Same for pistol, 357 mag, 41 mag, 44 mag, etc. Usually use with ball powder and/or very slow burning powder. Check for recommended primer for any given powder in an up to date loading manual.

  Read manual, use what it calls for for THAT caliber, bullet, and powder. Mag primers have a smidge of powdered aluminum added to primer mix, greater heat, does better job of lighting slower powders. For .357 target loads, I use standard primers with Bulleye or Unique, but load some rather stout 165 gr solids over 2400 powder (10 inch barrel) and manual does call for mag primers for that load. Mag primers CAN change the pressure curve on a load, so stick to the book.

  yep,..they are better for large magnum powder charges or slow ball powders. In a pinch, drop your load by a small amount and work back up with magnum primers,...same/same.
