I have a few bricks of it that I purchased during the 22 shortage. Let's just say that in my rifles (Cooper, Tikka, CZ, all sporters) it gives "adequate" accuracy - about 3/4" for five shot groups at 50 yds and sometimes a bit larger. It is very rare to have a fail to fire with it.
I do have better accuracy from CCI S/V in the same rifles though - about 1/2" five shot groups at 50 yds and just as reliable, although I have read some reports from folks saying it does not operate reliably in semi-autos but I have no personal experience with using it in them.
CCI S/V is generally less expensive than Mini-Mags also.
Making holes in paper - CCI S/V.
Shooting gophers - CCI Mini-Mag HP.
