Another vote for Jerry's. Powder and primers are usually cheaper than anywhere else. Other things you can find online cheaper but I like supporting the local shop. Plus if you have questions they are always willing to help and full of knowledge.
Took my daughter to my parents in Missouri for opening day of rifle season. Got her first deer at 7am that morning. I told her that's not the way it always works.
The 3 box limit is only on 22 now. The best way to get results is to go to the customer service desk. There is s sign there with the market managers name and phone number. Call and most times you will get your way and sometimes they will make the store also give you a gift card.
I started reloading 9 recently. Not for the savings but more along the lines of what some others have said. I like being able to make my own regardless of what is available on the shelf. It's also better quality and I enjoy it.
