I have been reloading the Hornet and K Hornet for almost 40 years. Some folks say that it is difficult to load. Not so, I have buckled a few shoulders, but it was my fault for not having chamfered the inside of the necks. With Lil Gun powder you get over 500 loads per pound.
If you don't reload, check out S&B ammo. They are quite reasonable from what I've read. I got some of their once fired brass in a trade. It works well.
