Every bad round hat was ever loaded was because it was loaded on a progressive, or was that a Dillon, or maybe it was a Lee, or was it the Tightgroup or maybe the Bullseye before there was Tightgroup, or was it using magnum primers in standard loads, I forget.
I've been reloading for 50 years (I started reloading when I was one) over 750,000 rounds of ammo (don't check my math) and never made a bad round of ammo or mistake ever, or maybe my memory isn't that good anymore. In fact I can't even remember why I have that plastic hammer and brass rod in my range kit, or how the bullet pullers ended up on my reloading bench.
So do things my way and you will never make a mistake either.
