I was not quite done posting but it seems that I hit the post button. I was running into the shower. Hence the "no," however for some reason I thought I saw the word trim in there.
Anyways both of your comments are correct. I'll measure every tenth or so just to make sure the sizes are on the ball. I have had good luck and accuracy with variable sizes so I am not that picky, nor do I have the time and patience to measure each case. All my brass is once fired WWB 9MM so its pretty spot on to .755 or whatever the correct length is, it escapes me now. Resizing is yep, its done for me when I pop my primers out and if I don't the bullet falls right down which won't be good for OAL now would it?
My reloading experience is small compared to what some of you guys have, but I ask. Where do you buy brand new brass and by that do you mean never fired, never filled or seated with a bullet, like what the factory will stamp out before producing the cartridge?
Also, just ignore this whole post because the OP was talking about rifle brass.
Good day sirs.
