Reloading: 300 BLK Recipes

Reloading: 300 BLK Recipes

Around 15 years ago, a co-worker suggested that I look into reloading as a hobby. I knew nothing about the topic at the time. He suggested going the buy once cry once route: spend lots of money up-front for decent equipment, and you won't have to worry about replacing it later. I ended up ordering a Dillon 550B. It wasn't cheap, but it's held up amazingly well and is still the only reloading press that I own.

Fast-forward to present day. I picked up a ProChrono DLX Chronograph for measuring the speed of my rounds. It works extremely well: shoot, wait for the measurement, shoot, wait for the measurment, etc. You then use their app to pull all the shot strings onto your phone via Bluetooth. Honestly, I have no idea why I waited so long to purchase one.

That being said, I figured it was time to share all of my 300 BLK recipes and the associated data. Enjoy.
