This is fast becoming a popular cartridge, even in bolt guns.
I know there is a 5.56x39 that was invented by the Russians for the AK74 rifle and used in Afghanistan.
It has a long tapered FMJ spitzer with a cavity in the tip, much like the 303 MkVII 174gn bullet, which induced tumbling upon impact and increased lethality.
But has anyone played with this cartridge necking it 6.5 or 7mm, etc. and altering the case taper and shoulder angle.
I could see it being an effective cartridge as a 7x39 Improved with a 35 degree shoulder mustering more power than a 7-30.
You could also wind up the boost a little as it's a rimless round.
