I can’t speak of the Winchester LP primers…..but, Winchester Large Pistol Magnum primers were the only one’s (to my knowledge) recommended for handloading the 460 S&W Magnum! memtb
No such thing.
Perhaps I should have stated, that in my data they were the “only” ones recommended. YMMV In fact they were emphatic enough that I bought a few bricks of them for that sole purpose! memtb
