~ Unique Options ~
Lighter than Light
Heavier than Heavy

4-Sigma offers the handloader a number of options unavailable anywhere else in the industry: from very light to very heavy. We’ve been around a long time. Our first bullet patent was issued in 1973, and since then, our product line has continually expanded.

Our name, 4-Sigma Bullets, is indicative of the uniqueness of our bullets. Our products are way out in the tails of a “normal” distribution; and, in fact, no other manufacturer makes lighter or heavier bullets than we do.
