1 review for 600 round box 300 Blackout polymer coated 220 Gr Spire Point
Rated 5 out of 5

They worked great with 9.6gr H110 in 8in AR barrel. I use a Lee expander die to open the case mouth slightly to avoid shaving the coating off, kinda like loading for handgun ammo.
2MOA group without any fine turning.
