Anymore, I'll shoot almost anything I can get my hands on at a semi reasonable price.
I have shot Remington, CCI, Federal Bulk Pack, Aguila...
Several years ago (10?), #2 Son did his Senior year Science Fair project on the precision of commonly available non-target grade .22LR ammo. He used my Leupold-scoped, Shilen match barreled, custom stocked Ruger 1022 from a solid benchrest. We bought one 50-round box of everything we could find at Walmart, gun stores and gun shows and ended up with 18 different 50-round boxes to test. All of the protocols he followed are way too long to detailed but he fired +/- 900 rounds in 5-round strings at 50 yards on NRA standard pistol targets. The velocity of each shot over an Ohler Chronograph was recorded, each shot was numbered on the target and each target was statistically analyzed. His results showed that the old Federal Bulk Pack ammo came out on top with Aguila yellow-box a close second.
His project qualified for State competition where he finished 3rd in the Physics category.
