Practicing is a waste of ammo?
It probably is if you don't think you can improve.
Depends on what type of ammo you’re looking for. If I just need plinking stuff i go to academy, but for my hunting and long range stuff I use Dallas Custom Reloads. Chad is in the Lewisville area and makes amazing ammo. He will also do custom orders and do load ups for your rifle if you need that.
Might look at grabagun.com. You probably know of them. An on online retailer, but have a small storefront in Coppell a little east of Bass Pro Grapevine and north of 635. They have good ammo prices and sometimes some great deals and $12.95 flat rate shipping for ammo regardless of the size of the order, but can also elect no shipping and pick up at the storefront for free. At least I assume you can with ammo as I did with firearm purchases from them in the past.
Not your traditional walk-in "gun shop," but local nonetheless and competitive prices.

If you can pick up in Coppell you can order on line and just drop in and pick up. No shipping cost. I’ve had good experiences with GAG
