  • Recrown at home

    Good day, all.
    Would, could, someone please advise me on home recrowning of a 22lr. I've been looking on the net at some of the recrowning tools. Not sure what a lapping tool is for.
    Would appreciate any advice.
    Thank you.

    The lapping tool rounds off the edge of the bore. The crown is the last thing that touches the bullet as it leaves your gun, so if there is even the tiniest nick or burr on the edge of the bore the bullet could get thrown off, have lead shaved off or tumble.

      I bought a muzzle crowning tool from Manson Reamers and did my old Bentley 500 crown.
      Worked a treat
      (I got a 30 cal mandrel as well, for OP's guns)
      To lap, I used a brass dome head screw with valve lapping paste.
      Wipe it with a cotton bud to see if it pulls any fibers.

      just sayin'.

        The muzzle is the most important part as regards accuracy and as Chang said (above) all sorts of things can happen if the muzzle isn't right.
        You can forget all the other variables if the bullet is being adversely affected by the muzzle.
