I have thought about plated, but don't have a chrony just yet. Hoping to get one soon though.
You dont need a chrony to shoot plated, any more than you do lead or jacketed. Work up the load as you would with any other projectile.
One more note- precision delta has jacketed 9mm for 8.5 cents each, shipped.
If it sounds like I am trying to talk you out of lead, I am not, I like lead, but unless you have a really cheap source of lead bullets you are unlikely to save much if any money over plated or jacketed.
