Are you doing all your reloading on your Dillon? 3031 and 4198 will give you some headaches running them through a progressive press.
only using the dillons for pistol calibers and .223, I don't really mess with em much, my dad runs them more then I do, up until recently I didn't shoot enough pistols to warrant my time with reloading (maybe 100rnds a year)
for my rifle rounds, I hand weigh the charges, might end up being different story in the future.
