[QUOTE="J E Custom, post: 1451582, member: 2736"] I also use 50 BMG with the 200 grain Partition. My most accurate load is 117 grains at 3260 and the fastest load is 122 grains and I have to use a drop tube to load this beast. I have the SAMMI freebore but the 117 grain load produces 1/10 MOA groups. (Average group size 5 shots .092 to .297). The fastest load is still accurate with less than 1/4 MOA but it produces a fireball that Is shocking. (Caution must be used when approaching this load and it must be worked up to). My rifle has a 30'' barrel with a 1 in 10 twist and is built on a Mark 5 Weatherby action with a magazine length of 4.000 +. I would try heavier bullets, but don't know if they could do better in my rifle. J E CUSTOM [/QUOTE]
