Measure the distance between your bolt face & the rifling, if you don't know how, this is how I do it.
Put the bolt in the rifle cocked, obviously unloaded,slip a cleaning rod in from the muzzle untill it stops at the bolt face, mark the rod at the muzzle. Remove the bolt & stuff a bullet in the chamber ( a bullet, not the cartridge), push a pencil against the base of the bullet to stop it moving back & again put the cleaning rod in from the muzzle, when it touches the point of the bullet mark the rod again, measure the distance between the 2 marks reduce that distance by 1 mm & that is your maximum seating depth for that bullet. Sounds long winded but takes 3 to 4 minutes.
