You know my MO. I went from not knowing what runout was and enjoying shooting, to hearing someone tell me I need to check for wobble, and I seen it, tried squaring my dies (waste of time IMO but I still do it), then changing shell holders, to buying a concentricity gauge, to the dreaded neck turning, then buying competition redding seating dies, to fireforming with cream of wheat, (this point I started making reloading no fun) then finally after all that for years and years, I started using the collet die along with floating my shellholder.

I should have skipped all the rest and just got a collet die and learned how to float my shell holder. It would have saved 1000's of rounds and a lot of head shaking.
