I really poo poo'd on 300 Black out when it first came out. Not great accuracy, lots of drop, slow muzzle velocities... I've got two now and I would not hesitate to pick up my 16" Rifle. It was a hodge podge of cheap parts, I found on sale and it flat works. AR stoner barrel shoots MOA out to 300 yards, Primary Arms 1-6x 300BO ACSS, Matrix handguard. Geissele G2S in a Palmetto complete lower. The scope is dead nuts on its BDC out to 400 shooting 1/2 sized silhouettes. The 16" 1-8 twist AR stoner barrel gives me 2400 fps with Win296 and 110 Vmax, and 2.5" groups at 300 on steel. Its not as fast or as flat as a good 50 grain Vmax in a hot 5.56 load. But if you use it at real coyote calling ranges, you'll destroy them. No runners...
