Generally very accurate, easy to reload. 45 grain hollowpoints is what I used for groundhogs out to 100 to 150 yards. After that the trajectory falls off pretty fast and range estimation starts to be more of a problem.
These days, it seems that the .22 Hornet is seen as the old guy on the block, guy that used to be right decent, but has fallen by the wayside.
Are you just looking for ammo to buy for an existing rifle, or are you contemplating buying a .22 Hornet-chambered rifle and are also seeking ammo?
I'm NOT much of a rifle shooter, and I'm certainly no "varminter", but if you're looking to buy a rifle, my own personal opinion is that you seek another chambering; one more common and "better".
But if you're just after ammo... Wish I could help.
I would compare it to a 22 mag rimfire that you can relaod for.
You should get at least one box of standard 22 hornet shells with higher weight bullets and one box of lighter weight bullets if you are buying factory. You might consider also what you are wanting to do with it, targets the heigher weight bullets are great. On something like a wood chuck or garden pest the higher speed more explosive ones work great.
It is a reloaders gun as you can reload it very inexpensively. Brass does wear out quickly. lil gun powder is a nearly perfect powder for the 22 hornet.
How did you come up with a hornet around here. Even when they were popular not lots of the were not made. Browning made the a-bolt micro a few years back in 22 hornet and the contender barrel is popular and I thin CZ makes one.
