They aren't claims, they are fact. Plated bullets are inferior to quality match JHP and at subsonic velocities in 38 special/45 ACP, swaged LSWCs.I buy from Freedom Munitions. They have free shipping deals all the time.
They sell new and reloads. I haven't had any issues with the reloads I've purchased.
Their reloads use "copper plated" vs "copper jacket" bullets.
Some folks claim that the plated bullets are not as good or don't produce as tight a group.
