Re: .308 brass--which brand do you prefer?
I've only used Lapua so that is all I can speak for.
I guess first thing you gots to decide what you want out of your brass, and how much $$$ you want to spend.
On my GAP 308 the things I really liked about Lapua brass were -
#1 Consistancy ( volumetric and dimentional), and minimal prep
#2 Case life. I got 17 reloads out of a batch before I got a failure. YMMV on this. I just wanted to see for myself how many loads I could get. During this whole time the primer pockets held up, TIR well within 0.001, and velocities were consistant.
All the above I believe can be attributed to better initial quality in manufacturing. You pay for it though...
As far as cons...well, like I said price, but if your time saved in prep is worth something than IMO it's worth it. Another, is if you were to ever go to a match were you pretty much had to wipe your a$$ of a good portion of your brass, than you might feel a bit butt hurt.
