Markco, you're grouping the 243 with the 264mag, the 30 carbine with the 30/378wby...and you're calling threads on the 6 pistol battery SILLY?
I do think they are all silly, yes, but still interesting in some respects. The groupings are purely based on bullet diameter, nothing else. Not a dream, not a perfect battery, just something that was interesting to me. A few people have listed the 7 out of the 7 groups. The thing that is most interesting to me about these types of threads is the huge number of responses that don't even answer the OP. Maybe that is another question for a different sub-forum though.
