Just an old guy putting his 2 bits in. Rule # 1; If you didn't load it, don't shoot it, unless it is comercially loaded ammo. Rule # 2; See rule # 1. Do you get my drift? Practice, practice, practice and then practice some more! If you are going to trust your life and/or the ones you love on your equipment and training, then you need 110% confidence in your self and your equipment! Any range that required me to buy their ammo would see me doing an about face and out the door I went!! Find someplace else to shoot, get into reloading and roll your own if cost is an issue. A caution here, if you reload, you won't save any money, but you'll shoot more for the same amount.
