I use Federal Bulk pack from Walmart for plinking and general practice. I've found it to be the most reliable of the cheap bulk ammo. My bullseye gun (Ruger Mk3) gets the Aguila SVSE from the CMP. Off the bench, it shoots a ragged hole at 50 feet and it doesn't cost that much. (I think prices have gone up, but I bought 3 cases at $200/case so I'm set for years.
