kjc,
As Chris said, they're good, but you'll most likely get better accuracy from one of the OTM designs, such as the Scenars. The Lock Base is an FMJ design, which is by far the hardest type of bullet in which to produce an accurate product. The Lock Base is one of the designs that gets used in military applications, where the use of a non-expanding bullets is required; definitely not recommended for most hunting tasks.
