Update, I got the Dillon case gage in the other day and so far all my brass fits in the case very flush. Hopefully once loaded it will be the same. But right now I been taking my time removing the crimps and hand reaming the pocket and razor first seems to do OK but its a slow process. Borrowed my buddies digital scale and getting ready just to do a few test on the Lee 1.6 cc dipper and how many grains; I also got 500 55g FMJBT bullets for about .104 cents each. I did not tumble the brass just washed them, any opinions on this?
I would emagine you did something wrong if headspace changes after loading the ammo.
What are you useing for powder?
Do you have a powder funnel?
