If and this is a very large if, the military ever got around to adopting a cartridge that has most of the 308 capability and handier like the 5.56, is there an in between length cartridge that could fill both needs and be the all around cartridge???
What case length would be needed? I would assume something exactly in between the 7.62 and 5.56 in length and have the same taper so as to not require the curved mag like an AK. I would also think that the caliber would be something like 7mm. The optimum bullet weight might be between 120 and 140 grains, or it might not. Do we already have a case like that or would one have to be designed? It would also have to be an in between case head/circumference.
Remember, this is an imaginary 'new' combat weapon that is a start from scratch design which might or might not look like an inbetween AR-15 and AR10. This would shoot almost as soft as the 5.56 and hit as hard as the 7.62 at distance.
Let your imaginations range free, but please don't turn this into why anything we have already is 'good enough'. There are too many strong opinions out there on both sides. This is a clean sheet and barring any large advances in plasma watt rifles, this will be a traditional case/bullet arrangement.
Cold, Paulo, TimW....If this is not in the proper forum, please feel free to move it elsewhere.
Just wanted to see ideas and have a good discussion of cartridges. Everyone, have fun dreaming and thinking about what would you do if you had the keys to the cookie jar???
