If you call CCI and ask, as I did, the nice lady on the other end will look up their primers and compare component numbers and priming mix quantities for you. But for this one, she knows the answer off the top of her head. The CCI #400 small rifle primers are identical to the CCI #550 small pistol Magnum primers. They are just in different packaging. She said CCI employees buy the #400s for their rifles and handguns all the time so they can buy a bigger quantity at a time and stock just the one.
If you haven't been using a magnum primer in you gun, back the charge down 5% and work back up to a velocity match to your usual load.
