I haven't shot any reloads out of my HP, since it is waiting to be picked up at my shop. However, I can say that obviously using non jacketed bullets cuts down on the cost a TON. I use a mix of both, I've found that with non jacketed bullets I have more rounds misfeed and have more problems chambering. Jacketed bullets when loaded properly work like factory rounds. Non jacketed bullets are dirtier and you have to keep a closer eye on your barrel for leading. Leading can cause overpressure.
Basically as long as you are careful, either one can work fine for practice.
