Forster makes a Universal hollow pointer for cast rifle and pistol bullets, Mid-way sells them for about $15.00 a set, they use a 1/8 inch drill for pistol and 1/16 for rifle, the debate on Hollow points in cast bullets for Hunting has gone on for years, personally I use a Lyman mold 358156 this is a Gas checked mold, I use a softer alloy for hunting bullets with this mold , without hollow points, I get good penetration, bullet retention, with moderate expansion.
