243, 25 super, 358 win, all on the 308 case, and I think there was a 22 and 270 tried back in the days when wildcatting was the thing to do. All of the experimenting was often times for pretty small percieved advantages. Why a 270X51 when the 06 length works so well, well maybe a short action rifle is a bit nicer than the long, but the differences are pretty small. I was bitten by the wildcat bug lo many years ago too and had to have a 25-06 and 35 Whelan before they were factorized, I must have chosen my wildcats pretty well since the big guys thought they were worth doing also.
