A decent round but I like my 6.8 Western much better.

6.5 cm has been adopted and given military designation. Now how much use will it see is debatable.

That sig round/ system looks good on paper but operates at pressure higher than i want to shoot. Wear and tear should be extreme as well. Not sure how long it will stick around .

There has been an awful lot of money spent trying to replace the 5.56 and poor preforming kills when there are all ready guns that do that and we had even before switching to the m 16.

Best part is the original m 16 had better performance killing. It had a 20" barrel and slowere twist 1 in 12 if im remember correctly. Thaid gins it about 300+ more fps than an m 4 and the bullets destabilize much sooner turning sideways inside the person and then breaking apart making a larger wound and more damage.

PF id be curious as to your load in 260 that has less drop and drift than a 300 WM. I dont see that as possible unless your comparing a high bc bullet in a 260 to a low bc bullet in the 300. A 300 can push as high or higher bc bullets faster than a 260 unless your just running the 260 at some very high pressure.
