I did a 100 group size test with this ammo, two weeks ago, along with other brands and it did not group as well as others.
Test gun: M&P Sport 2 with Vortex Spitfire 3X optic and trigger pull modified and breaks clean at 4.5lbs. Gun was rested on sandbags and a front rest.
Test groups: three, five shot groups, wind speed in gusts of less than 5mph.
Ammunition: Gun was sighted dead on using IMI 55gr fmj and averaged 2 inches. Next up, IMI 62gr Penetrator (steel core), shot to exact same point of aim, but groups opened up to 3 inches. I then tried the Wolf Gold 55gr and it also shot 2 inch groups, but point of aim shifted about low and left, about 2 inches off center. Lastly (so far) we tried the Norma Tac 55gr fmj. It shot odd shaped groups, about 4 inches across. I pulled a bore snake through it, after each brand tested.
If I'd had a more powerful scope, all group sizes would probably tighten up a little, as looking at a 4" target at 100 yards with a 3X magnification, is like quartering fly sh*t with the crosshairs.
