Somebody gave me a 1000 heads of 147 gr lead truncated cone bullets to use up. I'll be shooting them out of a Rger SP 101 revolver so cycling is not an issue. I have W231, unique, Bullseye, Clays,red dot and blue dot handy. I'm looking for loads that will be safe and moderate in recoil/flash etc. Any experience /advice with these hevier lead heads appreciated.
