140 gr SSt Superformance
I bought a Mossberg 4X4 last fall in .270 and a box of Hornady Superformance 140 gr. SST, and a box of Winchester loaded with 140 gr. Nosler Accubond. Both boxes shot sub-MOA. I killed a cow elk with the Accubonds, so developed a handload using RL-22 powder to duplicate the factory ammo. The handloads group under an inch as well.
