"I have listened to the 6.8 vs 6.5 vs 6mm vs 5.56mm for awhile. SO! What do yo guys feel about he rounds and do you think that these new rounds are really needed?"
Things come to mind when I hear this come up - rifle vs carbine, urban vs open country side, small and fast vs big and slow, general purpose vs specific, the list goes on... and you can't have it all.
I grew up hearing only "Only accuracy is interesting" and if a 45acp, 12ga. and a 30 cal saved the world twice don't you think it could do it a third time".
I think we would be well served to get back that way of thinking "bang, thud" and focus more on accuracy, making riflemen and being proud of it. That being said
5.56 is what we have, but man it seems pretty weak when stacked up against current Russian and Chinese rounds or any other possiblity. I know any self respecting hunter wouldn't use it on anything past a ground hog. The Military has made it work and it seems to do the job, if the rifleman does his or if not, I would hope they would get rid of it, same with the 9mm.
I have some experience with the 6mm, BR, PPC rounds and they are amazingly efficient and accurate rounds, the 6.5 Grendel follows in their foot steps. This would be a great general purpose round, which is what some are looking for.
The 6.8 is a 30-30 in my mind. It is a good round but always wanting more in the end.
"I have had my wee wee smacked for some of my comments on the subject."
I am sure I will as well.
