I like Redding dies for precision rifle reloading on a single stage press where I do all my rifle. For handgun I like Dillon dies as they are specifically designed for a progressive press and I load pistol on a Dillon RL 550 and on a Hornady LNL. I have some Hornady dies in the LNL, but I replaced the Hornady Titanium Nitride re-sizing die(they make their sizing die this way) when it wore to the point that it was not resizing my .45 brass enough (remington brass) to ensure good bullet tension with plated bullets in remington cases in .45 acp. I replaced it with a Dillon resizing die, and my problem disappeared. I also own Lyman, Lee, and RCBS dies for different calibers. They all work but the Dillons are made really well their decapping pin design in the resizing die is spring loaded and floats a bit in tens of thousands of rounds I have yet to have one break or bend. I also broke a Hornady seating die insert in .45 acp due to the bullet falling over. Hornady sent me the parts free of charge.
