Been lurking this post for some time contemplating doing my next AR in 6x45. Iíve pretty much made my mind up and gonna order a barrel soon probably a McGowen going with a 20Ē and probably 9 twist which is where Iím still up in the air is twist rate. Iíve got 55gr Sierra blitz kings, 62 Barnes varmint grenades and 75 vmax. My 243 shoots the 62s and 75s nicely but I wanna try and go lighter pills for the 6x45 55-65gr preferably.
