Grendel at extended ranges?

If the 77gr SMK or Scenar are pushed fast enough or in a node to that barrel, a 1/9 could stabilize them, but 1/8 or 1/7 are definitely the recommended way to go with longer bearing surface .224 pills.

The 77gr SMK with Cannelure is used for the Mk262 5.56 load, IIRC. 77gr is a great mag-length loadable pill for 5.56 work at intermediate distances.

I agree wholeheartedly on the 77's. I use both the 77 SMK and the Hornady 75's in my match AR. It's a 1:7.7 twist and is very competitive. These are also the last bullet weights folks should probably try load to mag length. For single load I use the 80 SMK's. In my match, I get 2871 with Varget. In my 1:6.5 twist bolt rifle with 30" barrel, I get 2960 with 8208.
