Don't think so and I've been a 22 fan for more years than I care to remember.I've successfully used my Swift on deer and speed goats since the mid 70's with cup/core stuff but the the 6mm's are and have been very popular all over the country and kill stuff quite well.I think for the most part it hinges on factory over the counter availability and we sometimes tend to forget that lots of folks have never heard of a Partition,TSX...etc,etc.
