I did, for me, Hornady came out on top. YMMV
You made a statement of fact not a statement of opinion. There is a difference.
I don't see any data supporting your assertion. Just opinion on what you prefer.
I ran my tests too albeit I was using the 221 Fireball as I don't have a Hornet. I had several weights of bullets from different manufacturers and put them into similar classes. I used several powders and a few different primers.
Simply weighing the bullets for consistency is pretty telling. I suggest this to the OP as a good starting point.
My accuracy tests were very straight forward. Several groups of 5 shots based on the smallest spread. Even the old cup and core bullets came out on top of the Hornady bullets for accuracy. Ran the same tests with their 180 grain SST bullets in 30 caliber, not good. I sent 14 bullets from the same box back to Hornady because the weight ranges were a low of 131 grains up to 182 grains. Never heard a word back from them. I found similar variance in the V-Max bullets. I didn't find that with Nosler and Sierra.
Powders testing was interesting, accuracy was greatly influenced by powder selection. I tried 1680, H110, 4198 and Reloader #7. #7 came out on top.
Primers made the biggest difference in accuracy. You want the mildest primer you can find for small cartridges, let the powder do the work. You don't want to dislodge the bullet from the case before the powder ignites.
The Nosler Ballistic Tips and the Sierra Blitz King bullets are the best.
