I have an accuracy load of 36.5gr of AR2208 with a 55gr Sierra Gameking (Super roo), however, the velocity as tested with a Magnetospeed is only 3455 fps. The ADI load data has the max load of 36gr as 3730 fps with the same bullet.
What is going on here? ADI manual unrealistic? or Magneto inaccurate?
Can anybody provide any answers?
Cheers,

Thanks Bill, I got out last weekend with my 223 and shot four groups, two of the best measured 0.350. not my best shooting but not bad for a factory rifle with 4,000 rounds down it. How did you go?

Thats some good shooting SCJ429 sounds like youve got an accurate gun
Cheap new bullet for the 6mm on friday, ran out of 8208 and not enough 2206H on hand so substituted in Re10x. Zero reloading data available for this combo so I was ultra cautious as its a bit on the fast side. 2nd group went 0.4 so I found the low node, groups opened up with more speed and top speed a bit away 1-1.5gr. Will play around with the seating depth once Ive found or not found a top accuracy node. I only started using a powder thrower recently, teaspoon is back in the draw
64gr at 3360fps.
