Default Small Pistol Primers vs. Magnum Small Pistol Primers

I usually use CCI #500 small pistol primers for my 9mm loads (4.3 TiteGroup under a 115 grn FMJ). I have some CCI #550 magnum small pistol primers in my stash. What is the difference between the #500 and #550? Should I adjust my load? Thanks folks.

You're loading below the recommended starting load for a jacketed bullet.

Been there done that. All I ever found was about 30-40 FPS faster with Mag primers over my chrony

Your load is so light there's no reason to reduce the charge when using a Magnum primer.

Good morning
For plinking and below max loads of slow powders a Mag primer seldom makes much of a difference. Benchrest shooters and "Machine" shooters might see a slight accuracy difference.
If you have no intention of loading 296 or H110 or similar powders in 357 than use them up.
