There's always someone who misses the point and tries to solve someone's "problem" for them. LOL I handload and can build just about anything I want. My question is that with the proliferation of new calibers over the past 20 years, why hasn't someone come up with a .30 cal in between the 7.62x39 and .308? The 7.62x39 is plenty for deer and hogs within reasonable distances, but most folks consider it underpowered but pleasant to shoot. On the other hand, the .308 is more than enough for deer and hogs, but most folks don't want to shoot it in a lightweight hunting rifle for very long. Notice I said "most folks" - and not manly men who thrive on recoil.
Add to that the declining popularity of the 30-30 (America's deer cartridge) and lackluster accuracy in lever guns, and it seems that by now someone would have come up with a "Thirty Deerfield" or the like, selling it as the perfect American whitetail caliber. And who could argue with that? Recoil like a .243 but with common .308 bullets and I would imagine superb accuracy. Every time I load my .308 down with 160 grain FTX bullets, I am amazed at the shootability and accuracy of that combination, not to mention effectiveness on whitetails and hogs.
