Thank you Pulki, Darryl, then it seems I am chasing shadows...it then is a myth that seating out the bullet to 91 mm will not give you really a lot more velocity than using ammo bought from the gun shop shelf...still there are people who are adamant about the necessity to build a 8x68 on a magnum action only...????? Will it be better to use a ZZK 602 action than a standard Mauser 98 action for better feeding instead to use muzzle velocity as the rationale ?
