I've tried the 55gr Campro bullets out in to of my my AR15s in .223, and two other rifles in 22-250. Compared to the same loads with 55gr Hornady V-MAX bullets, I get groups that are about double in size at 100y. This doesn't surprise me since they are FMJBT bullets with exposed bases, similar to military style bullets and are definitely not sold as match bullets. I bought these bullets for short range CQB style shooting and find they are perfectly ok for this and priced right. If you want better accuracy, I'd recommend the 55gr Hornady soft point bullets in bulk packs. They are a little more expensive but more accurate. Anyway, just my personal observations on this bullet, yours may be different.
