I use the Hannedline 22lr die that allows you to file a meplat semi wad cutter profile on the nose of the bullet. It Is a nice upgrade for the LR. making it noticeably more effective on big critters. It is worth while mod. The hanned line company is out of business I would love to have one of their 22 mag dies.
I have one of those Hanned Line filing tools too and the re-profiled bullets really penetrated well, and the flat point did drop barn pigeons well!
In my rifle,ammo shot the same before and after the Hanned Line modification. The same 4 or 5 brands of ammo shot better after being reshaped in the Paco tool (presumably because the bullets were now a littler larger diameter?).
