If you shoot a lot it's a must. Factory reloads at my range are up to $14.00 a box of 50. I can turn them out for less than $5.00 a box. That's .45ACP's. Buy good stuff and it will last a life time. The only concerns are go slow and pay attention to what you are doing. What I like is I can tune my loads for my guns. The big booming rounds don't always get the job done as you'll fine out. Go for it you'll enjoy it. I do.
