It is a fantastic varmint round.
It was very popular among varmint shooters right out of the gate. But it has ridiculous pressure spikes and a lot of semi-autos were recalled accordingly.
If you can get one in a bolt gun or single shot, and lay in a good supply of ammo, they are well worth the effort. But I will add that it is awful in high winds and some modern 22LR gives an equivalent "pop" on a rat or rabbit.
They are insanely accurate. Typically.
