there were quite a few wildcats based on the 30-06 case. Any time we are involved in a war when it is over there is plenty of surplus brass and ammo so it is perfect for wildcatters to experiment with.
The 6mm/06 was one of those. I don't think it went anywhere but it was fun to experiment with as brass was plentiful and in many cases was free so why not. There were the 25-06 (which caught on and became a standard cartridge), the 6mm/06, the 6.5/06, the 7-06 and maybe one or two more. Of all these as far as I can remember the 25-06 was the only one that became a factory chambering.

After the Korean War the 308 case was [plentiful and there were several wildcat cartridges based on the 308. Several of them became factory loadings.

After Viet Nam the 223 case was plentiful and there were a whole batch of cartridges based on it.The silhouette games were popular as they still are and there were several wildcats based on the 223 (or5.56). Some of these like the 223 necked up to 243 and 7mm that caught on and were being loaded by a couple of companies. Good friend Bob Milek came out with his 6mm/223 and it was popular in the silhouette games but they never made a factory chambering from it. We tried the 223 neckd up to 7mm in the 7mmTCU, developed by Thompson Center and Wes Ugaldi, hence the name TCU. It was accurate but just didn't have the needed punch for large bodied deer.
