No need to Full-length size new brass!! Just run the necks through the expander button to make sure they are perfectly round, chamfer the inside, and load away! In my 45 years of reloading, I have learned to eliminate chores that have no intrinsic value, and full-length sizing new brass is on that list. Regards, Eagleye
I have bought new brass and tried the brass in the gun even before attempting to reload. Many of the brass would not even enter the chamber thus showing it was too large in diameter. I would not force it in as it could prove to be a real chore to remove. Even the die showed which brass was oversized. Did i just get a bad batch? It certainly does not take longer to full length resize as to neck size the brass, just the full compression of the handle.
The first brass I reloaded, I did not full length resize and when attempting to check each cartridge before venturing on a 300 mile hunting trip, I found some that would not fit the chamber. I took them apart and started over again by resizing . Better safe than sorry I say.
new brass. rem or win gets the treatment. lapua, hornady, norma is usually ready to go from the box
full length size
uniform primer pockets
trim to uniform length
uniform flash holes
chamfer and cleanup the necks
doesn't take all that long to do. i use a rcbs prep centre.
