Purchased this gun several years ago and finally getting it set up for coyote hunting. S&W MODEL M&P-15 with 16" barrel and a 1/9 twist with a Redfield 4 x 12 scope. I have it sighted in on paper with just some cheap .223 fmj loads that came with the gun. It came with about 2000 loads of ammo. I know every gun can be a little different with loads but hoping someone might have a "like" gun that has already found a very accurate factory load for yotes without me going and buying several different brands of factory ammo.
