The first handi-rifle I purchased was a 22 hornet. I had an older Savage previously which made me a fan. The first thing I noticed was how inaccurate factory ammunition was. The first major brand ammo would shoot a group within the limits of a pie pan. The second major brand would be covered by a soft ball. At the time ammo for a box of 50 was 25-30 dollars a box and I felt, even then, it was too expensive. Now ammo is pushing 1 dollar/round and I am sure it is too expensive.
After working on the trigger and reloading many, many rounds, My last group was 0.25" at 100 yards. When I shot this group, I immediately stopped shooting, packed my bags and headed home from the range. Havent shot it in a couple of months for fear of losing that thought in my mind. Besides, I have other calibers to work on. They arent the easiest to reload, but are among the cheapest. Very little powder and you can reuse the brass many times. Generally I shoot about an inch group at 100 yards with my pet load/s.
I realize the 22 hornet is a different caliber than the 17 hornet but I cant imagine too large a difference in loading for them.
