I have a bolt action, so I'm not too concerned about how they operate in the gun, other than go bang and shoot straight. I would have to say that MiniMags are nearly the worst of 26 or so different loads that I tested for accuracy. In order of best to worst and excluding the more expensive target stuff as you requested these all tested better than MiniMags (I only tested the solid point version, and in my experience SP is almost always more accurate than HP).
CCI Standard Velocity
Remington Cyclone
CCI Velocitor
Federal Gold Medal 719
CCI Stinger
Win Dynapoint
Win T22
Win X22LR
CCI Blazer
Federal Champion 745
The MiniMag came next with a 50 yard group size of just over 1". And these were worse still from bad to really bad:
Win X22LRH
Rem Yellow Jacket
Rem Viper
I wouldn't buy MiniMags again no matter what they cost. Perhaps a bad batch, don't know - but they had their chance and blew it. Way too many other better alternatives at least for my gun.
