Accurate & soft recoil - Fiocchi Range Dynamics .223 62 Grain FMJBT Rifle Ammunition

Shot this from 2 rifles and both grouped under 1/2 inch with 1-4x magnification from 50yards. My barrel with 1:8 twist made almost one big hole. Another thing that stood out was the soft recoiling from 62gr. I don't have a fancy buffer system or adjustable bcg or gas block. I'm not imagining things because that day I tested 9 different brands and 3 brands shot softer than normal with the Fiocchi being the softest. I haven't confirmed it at longer distances but will out to 650yds. I do 2gun run & guns in hilly terrain and the 62gr is a great round to use against some wind.
