After consulting with you good folks here on the fire I recently purchased a CZ 527 in 17 Hornet chambering. I decided to buy several hundred rounds of factory ammo to shoot for an upcoming prairie dog shoot. After initial sight-in, I found that the 20gr vmax factory loads wouldn’t shoot any tighter than about 1 moa. Since I had a few empty cases to load I tried CFEBLK with the bullets just off the lands. Eureka! Consistent sub-half in. 5 shot groups. Turns out the Hornady factory loads are seated too deep for my rifles. I pulled the bullets and reseated them to my hand load’s length and they shot just as well.
I truly can’t remember the last time I have had as much enjoyment with a firearm as I have had with this rifle. Accurate,mild report,virtually no recoil, and inexpensive to load for. I love it! Prairie dogs not so much.
