There seem to be innumerable Double cartridges and one wonders are there any gaps to be filled??

For short range open sight Double scenarios (150 yds or less)it would seem no gaps exist---

Once we consider scopes on Doubles and their capabilities for long range accuracy gaps may materialize--

***If one where to develop an American all round Double I would think a 30 cal wildcat based on the 7x65R shooting 180 gr bullets(a rimmed 30.06 equivilent)would have appeal.It could feature true ejectors, a qd scope and other features(read expensive!!) high end hunters would desire/appreciate.

For those who would hunt elk/moose/grizzly a 338 caliber would be great.The 333 Jeffery Flanged in 338 would be fun or maybe even the 375 H&H Flanged necked down to 338 caliber!!

Does anyone else want to wildcat a Double cartridge for a specific hunying purpose??

What wildcat would you create??
