Good day. I I have a .222 Riihimaki. Which gr ammo will you guys say is more accurate for this rifle. 50gr 55gr 62gr I have used 55gr and my accuracy is very good. about half an inch grouping on 100m and 4inch grouping on 300m. with 55 gr on 100m my grouping is 2inch. I have never used 62gr. Will this also work well? Thanks.
