I've just noticed a warning on the side of a case of Remington 1 1/2 Small Pistol primers. It says not to use them in .357 Mag, .357 Sig and .40 S&W. Now I have magnum primers for my .357 Mag rounds, but what is the problem with .40 S&W? I have loaded and fired several rounds in 40 s&w with these primers with no problem. I don't shoot 357 sig so no experience there. Anyone here had a problem with Rem 1 1/2's and 40 s&w? I looked on the web site like it suggests, but the ballistic tables the box refers to isn't there for pistol calibers. If it is they hide it well.
