same load different groups???

I've pounded many a bullet out of factory Remington brass to load it as my own new. Running it through the sizing for the only resistance is the primer popping out. Generally they run 2.481-2.483 from factor loads after bullet is pulled. They're never 2.484 as per book trim-to specs
We're lucky they sell us brass at all. Handloaders aren't even a drop in the bucket compared to factory ammo sales, which in turn is peanuts compared to military sales.
From the point of view of factory ammo, lot to lot variation of brass means little. They don't have the same powder from run to run either, so little is lost. Ammo is loaded to pressure and on a good day; velocity. This goes to a buyer who takes his single box of ammo home and tries to make it last 5 years.
What do I do put a primer in and fill it with water?
...
Does a primer seated at 0.001" have the same water capacity as a primer that is seated at 0.007?
I have no idea what 1 drop of water weighs.
I can measure once fired brass and the primers can be proud.
Anyway, OP has more differences in his brass I agree, but I think I would try a spent primer backwards.
I'll put it in backwards, makes more sense that way anyway it's flat
I didn't punch it. Just put a new on in a new brass. This was the water weights of virgin and once fired. View attachment 425373
You'll want your full length sized too. Your die could give a different final dimension than this batch of virgin factory sized brass. Which in turn could be a different dimension than your last batch. Maybe try pulling one of your old loads that were good and see what the case volume was as well.
He only shoots virgin brass. He doesn’t need to fill length size anything.
Both fired cases out of the same chamber. Done.
Holy moly, ok. The old batch of brass fired same poi new and once fired. This new batch I had to drop 2.5 grains with the virgin brass to get back to where I was with the old batch at 55 grains when it was new. Nevermind what I'm gonna have to work up for this new batches once fired brass. I really do appreciate your guys help allot. Gunnutz has taught me everything from how to use grammar and construct proper sentences, to reloading advice, to learning how to speak and read kamlooky.
