The 250gr Accubonds are really shooting good in my 340Wby if I keep them somewhere between 2800 and 2900fps. The target below is .990" at 200yds.
Also I have finally gotten use to the trigger on my S&W AR-15. Below is a 20 round group at 100yds.
250gr Accubond, 77.7grs of H4350, 215 Fed primers - 200yds group size .990"
20 round group out of my S&W AR-15 at 100yds, Brown Bear 55gr HP ammo averaging 2907fps out of my 16" barrel.
