Dan... My cast bullet experience has been with Long Range BPCR rifle competetion. I used 20-1 alloy with a .060 wad under the bullet and never looked back. Now I find myself shooting rifles with cast bullets, using smokeless powder and with different (harder) alloys. From articles and books I have gathered bits and pieces of info on velocity vs. alloy and need your input to clear things up. One book says keep the velocity under 1600fps (w/smokeless) for the best accuracy (w/o gas check) but it does not say to use a wad (veg. fiber or LDPE) under the bullet to protect the base (which is what I used w/black powder). Another says you can load cast bullets up to 2400fps w/o a gas check (using Lyman #2); another says use a gas check for high velocity. Will a fiber wad or LDPE wad protect the base of a cast bullet at higher velocities (1800-1900fps)? Most of my "Hard Cast" commercial bullets are in the 15bhn range, I have some of my wheelweight alloy that I heat treated that are 22bhn (after 2 weeks). What guidelines do you recommend for (Rifle velocities) hardness, accuracy and hunting? Should I use wads under my 15bhn bullets (plain base) at 1800-1900fps? Or should I just skip the plain base and only use gas check bullets?
