I use Remington Brass. Mainly because its all i could find at my local provider, and with my abundance of 308 Remington brass on hand i found it very handy being able to neck down the 308 brass. I shoot a custom built 7mm-08 on a Remington 700 action and 1-9" twist Ted Gaillard Barrel cut at 24". I use 43.5 grains of IMR4007 SSC under a 160gr Sierra BTSP(Game King) and it all Ignited by a Remington 91/2 primer, and a 150 Nosler Hunting Ballistic Tip with 45gr of the same powder. I regular shoot long range and the reason I like the Remington brass is I seen no difference in accuracy or pressure between the 7mm-08 or Neck Down 308 brass. Makes my life easy, and with Remington brass easy to find its an added bonus.
Cheers
