If you had the choice of buying Federal, Remington or Winchester unprimed brass, which would you choose and why. Thank you in advance for any input.

P.S. I will be shooting 7mm Rem mag, 270 Winchester and 45 auto. Light target shooting and hunting it.

After my excursion thru a few of the big box outdoor stores yesterday...Id suggest you don't get too picky. In three stores I saw a total of 1200 pcs of brass, none of what you are looking for. I have more brass, primers and powder than they did combined.
Winchester assuming you do have a choice.

I use Winchester brass (when I buy it) for everything by one of my .243's...for some reason it really prefers Remington brass...my brother and nieces 243 is the same.

Thanks for the responses.

If you need to order brass try gunsandammo.com . They had 223 in stock. Been having a hard time finds brass for that caliber

Definately Winchester brass.

Winch. then Remingt. Rarely use Fed. Only in 45 and that only for I have buckets of the stuff.

Winchester here too!

Out of those three I also prefer Winchester.
