I'm new to metallic rifle cartridge reloading. I'm working on a load for 7mm Rem. Mag. I started with a box of Remington factory brass, once fired and they performed well. I have also tried a box of Federal premium, once fired, but they seem to be a bit thicker in case dimensions. Accuracy and energy are paramount for long range shooting. I purchased the Redding "S" die set with the competiton shell holders for precise sizing and headspace. I'm told that Remington and Federal brass are very good, but many fellow shooters are recommending Hornady brass. What's your experience with different manufacturers brass? Is Hornady a premium brass?
Thanks..
