Maestros - A lot depends on what rifle you're shooting and 'How accurate' you want/need. Fed Gold Medal is pretty good for 'low-cost' ammo that's NOT Bulk Cra*, but Fed A-M HV and Champion HV aren't as accurate generally because of being HV. However, some semi guns prefer the HV, so there's that to consider.
CCI-SV and Mini-mags are both very 'consistent' in speeds and reliability, tho the MMs are again HV.
I have several 22s that do Really Well with SK-Rifle Match or SK-Standard+, if you want 'better accuracy', but you're nearly doubling the Cost with those. Same for the Eley 'flavours', and both go UP as the Quality increases.
And the 'Stingers' OR the 'Stangers' will Beat up Your rifle/pistol, esp if it's a semi.
