AR15 in 6mm or 7mm TCU
« on: January 06, 2007, 03:00:33 PM »
Has anyone ever heard of an AR15 chambered in these 223 based cartridges? I would think the TCU rounds would work well since the parent case is what the AR is developed around.

6.8mm SPC is offered in the AR.  The cartridge is a bit larger so the bolt has to be changed too.  I agree the TCU would be nice but it is not an answer to anything except a slightly heavier bullet.

Maybe I am a purist but I like the .223 round and for other work where a heavier bullet is needed I would change weapons.

 I played around with both in the past through Hesse Arms, not really what I was looking for. Then settled in with the 300 whisper(.308 on .221 freball case). This is what I had in mind and has kept me entertained for several years now. The 6 was really to slow for predation. The 7 was acceptable for deer control with single shot pistol bullets. But the 300 really shines, it can be loaded with 125's for predation and 240's for deer control.
