I have shot a lot of deer with 143 grain eldx hornady precision hunters. Never noticed a blood trail because they all dropped where they stood. I have used them out of a weatherby vanguard, a browning x bolt hunter and recently out of a tikka. All 6.5 creedmoors and all shoot the factory ammo...
I also have the bases covered but won a tikka 3x lite in 6.5 creedmoor at a bash. I put a Swaro z3 3x10x42 mm on it and really like it. Shoots fantastic with Hornady 143 grain eldx ammo. Shot 4 deer with it the last couple weeks.
I had a weatherby vanguard in 6.5 creed for 4 years. Probably shot 25 or so deer with it. Never needed a second shot. I sold it because I got a great deal on a browning xbolt hunter in a 6.5 creed that a friend of mine won at a bash. Got it for 500 bucks. recently I won a tikka 3xlite 6.5 creed...
