The 8208 has been suggested a few times. I plan on giving that shot as well. I was told that Varget can be stored for a while. I was told to look at faster burning powders as well but honestly at this point Im really happy. My hunt load of 60gr V-max shots about a .8" average group and the 77GR SMK is averaging .48" grouping. These are really good in my book with a chromelines 16" penicl barrel. and
A_Gamehog. Its a Colt 6520. I believe its milspec and can handle the 5.56 mil ammo without problems. I know Ive shot some without any pressure signs or problems. In fact the upper/Barrel is labeled, 5.56.
