5030, you revealed your lack of knowledgeable about Dillon dies with your first post so your opinions on Dillon pistol dies are suspect. You are certainly entitled to your opinion, but it is wrong.
Loading rifle ammunition is not the same as loading pistol ammunition. Pistol shooters shoot a lot more. We need both decent accuracy and productivity. Trying to impress us with your handcrafting of rifle ammunition is deflection and not germane. BTW, I load rifle ammunition as well. I know that weighing powder to 1/4 gr is useless in getting a good load...just more BS to impress the ignorant.
My conclusions wrt to pistol reloading are based on shooting up to 20k pistol rounds a year, testing with a Ransom Rest, and a fair amount of competitive shooting. I have owned a Star, RCBS Green Machine, two Dillon SD's, two Dillon 550's, a Dillon 650, two Dillon 1050's and a Lee Six Pack. Old age has me down to one 550, one 1050 and the Lee for pistol ammunition, but this isn't my first rodeo.
