I see Lee makes a 230 grain 30 caliber mold. Don't know if my Ruger #1 30-06 can stabilize something that long. Would like to try it first before buying a mold. I realize this is a longshot but I'm checking to see if anyone could sell me a small quantity of this bullet.
Edit: Found this. The idea doesn't look promising.
