I prefer Federal brass components but will use Winchester whenever Federal brass isn't available for one reason or another. I just don't care to use Remington brass period. Been at this game of reloading nearly 50 years and developed habits and preferences. This is just one of my preferences. If betting or prize money is involved then buy the best. If for fun or leisure. You could get by with just about any manufactures cartridge casings. Even first fires. I'm sure your going to use whatever is available Op. Domestic or foreign. You have many brands to choose from Sir.
