The guy was loadind very gently. Look at John Barnsness article in Rifle some time ago, here in France with 225 Speer BTSP, 41,7grs of SP9 (close to TAC same manufacturer)i get 2365fps from my Tikka T3 22 in barrel, primer is CCI250, OA cartridge lengh is 2,82in.With a french powder close to IMR4895, slightly compressed we come to 2410fps with good accuracy and regularity (CCI200). With VN540 and 250grs Sako Hammerhead (CCI200) i got 2310fps good for close range big game. Cases are Federal.
All speeds mesured from a Gamma master � around 18�c temp and at 200feet above sea level.
