Funny how facts and proof can stare some of these folks right in the face, and STILL they just don't get it.
My old model 70 in .458 win mag usually got used with cast boolits. I cannot tell you how many times I was told I could not do that cuz of lead, and if I did, no accuracy. Yet 3-shot 100 yard groups of about 1.5" with PEEP SIGHTS were the norm and not the exception with cast boolits. Still did not matter: they weren't accepting the facts as they unfolded. Hilarious.
