Im running 62 grains of Retumbo in my 6.5 saum, ADG brass, CCI mag with 124 Hammer Hunters .010 off lands. Occasional slight ejector mark. Couldn't be happier, .3 to .75 moa out to 800 yard if I do my part. Extreme spreads consistently under 20 with my Lab Radar. My 15 year old son shot a Antelope this morning with it, kinda high,(just under the Back strap) and a little back,(just above the liver). Bullet entered and made mush out of back of lungs and half of the liver before exiting out the other side and boring into the dirt behind it for 2 feet then coming out of the dirt and out into the desert lol.
