I would like to make some target loads for my .405 Winchester using 200 or 220 grain bullets. I have been told I can use .410 pistol bullets. I need to know where to start. How much power and what kind of power would I use for this load. Any information would greatly be appreciated.

  Bullet diameter for the .405 Winchester was .412, so .41 Special or .41 Magnum with a bullet diameter of .410 should work.
  
  However, the loading data I have for the .405 is with a 290 or 300 gr. bullet, so I have no idea of what you should use for 200 or 220 grain.

  For 225 gr LEAD bullet20 gr 2400 powder=1514fps @10,300psi
  16 gr Unique pwdr=1595fps @15,000psi
  From Phil Sharpes' Complete guide to handloading.
  As these loads were probably based on the old folded head brass, you might drop the charges one grain to compensate for the current solid head brass. In any event pressures as you can see are low so it may not matter much.
