Does the brand of ammo make any difference in reliabilty?
(return to top) 100% it does! If the ammo does not have sufficient power to blow the bolt back and eject the case each time, the gun can’t run regardless of the mag you use. First choice for power and reliability would be CCI Minimags, which are also the most expensive. In the bulk ammo, Remington Gold and Federal HV Hollowpoints are about the same. The Winchester Wildcats are often underpowered and have unreliable primer ignition. So test with Minimags and then run the bulk ammo is the course that most shooters take.
