hello, I am looking for some proven bullet/powder combinations to reload light practice target rounds for my factory Glock 23. I need to get the cost of feeding this gun lower so that I shoot more for my money. I have pleanty of Winchester 231 powder left over from reloading the 45, and I would like to use this powder if possible. What powders/bullets are you guys using for practice loads? How may times do you reload your brass and do you have any case buldging with your reloads? thanks in advance!
