I am new to the site and amazed at the knowledge here. That being said, I am just returning to the target shooting arena and would like some advice. My goal is 1000 yds. I had a '70 generation 700BDL in .300 win mag that was a tack driver. I had to part with it some years ago and would like to replace the rifle. I had a friend with a FN Mauser in .220 Swift. It was a flat shooter as well. At the distances I want to achieve, would the .30 caliber be a better choice and what rifle manufacturers are recommended. I reload all of my ammo and have done so for years.
