In the late 60s and through the 70s I always bought Remington Hi-Speed and standard velocity ammunition because it was very accurate. In the mid 80s I noticed it wasn't shooting good any more, and it just wasn't one specific lot number. None of their Hi-Speed ammunition shot worth a darn, and their standard velocity ammunition is seldom any good either. I might occasionally buy some Remington .22 ammunition if it happens to be cheap, but I don't buy it for hunting or target shooting any more. Essentially it has been crud for the last 25 years.
For day in and day out dependable accuracy I've found that CCI standard velocity is very accurate and the Mini-Mag high velocity is accurate as far as high velocity ammunition is concerned. I've had good results with Winchester ammunition too. The Power-Point hollow points are accurate in many of my guns, and the hollow point is so big you can almost shove your elbow in them. They give great expansion on critters. Federal standard velocity ammuniton can be accurate. I've had trouble with some of their high-speed ammuniton functioning in some of my semi-autos, but it often is quite accurate in the guns it does work in. Almost nothing shoots as good as Federal Match and Federal Ultra-Match ammunition (except maybe Eley) but, unfortunately, they don't make it any more. I have several bolt action rifles that will shoot one-inch or smaller groups at 100 yards with Federal Match or Federal Ultra-Match ammunition.
