I’ve read that Navy Seal Chris Kyle, (American Sniper) used .300 Win Mag for most of his kills with a Mk-13 suppressed platform.
Yeah, we’ve read his book. I fired my bro’s .300win mag once; just once. I was sore for a week. For long range stuff I like my Savage .22-250 with 4,000fps rounds. It’s sighted in at 500yds.
