See below for update.
This Precision Hunter™ ammo from Hornady features “the 143 grain ELD-X™ bullet and carefully selected propellant and primer to deliver match accurate hunting ammunition.” Every gun is a bit different in how this ammo shoots. Below I tested it for bullet speed. It is advertized to shoot 2700 fps at the muzzle but does not state barrel length. I assume a 24 inch barrel but I am shooting a 26 inch barrel and as advertised it was 2700 fps plus my two extra inches of barrel making it around 2738 fps give or take. Nice!
I left the zero as it was from shooting Sierra 142 grain HPBT target bullet traveling an average speed of 2706 fps. Below are Groups 1 thru 4. Cold barrel shots are very different 1.3 inch group and high. I made no changes and shot groups 2,3, and 4. G 2 was 0.73″, G3 was 0.53″ and G4 was 1.45 inches.

This is good for hunting but I need to try these again in a separate experiment. At 100 yards these should all be within an inch. Need to test again in a clean rifle and may be the rifle. . Group G1 was shot out of a cold barrel as in hunting. Only G2 and G3 are sub-MOA. All will mushroom and kill game from close to far as slow as 1800 fps up to 2660 fps.
G4 shot should have all been together as in G2 and G3. More experiments planned soon to see what the problem is.
UPDATE
Cleaned a scrubbed the barrel July 4th and took to range. All shots are sub-moa varying from 0.97 inches to 0.25. This factory ammo is excellent for hunting out to 600 or so yards.
