This is a SINGLE FEED bullet. Our Lazer line is a high BC, tipped hollow point hunting bullet designed for excellent long range accuracy and devastating terminal performance. These bullets are all manufactured out of lead-free, solid copper bar stock on a CNC Swiss style lathe. Because of our precise manufacturing process, we guarantee all of our bullets to be within 0.2 grain (for calibers .308 and under) and 0.4 grain (for calibers over .308) weight deviation between bullets in a given box. Our Lazer line can be used anywhere from 0 - 1,000+ yards. The Lazer has quickly become the #1 ELR bullet of choice. These bullets do not mushroom, but instead, fracture. After 1-2 of penetration, 3 large petals will break off and radiate outward in a star pattern while the base continues through for even deeper penetration. Our Lazer line will expand down to 1400fps. Required twist rate for this bullet is 1:8 or faster.
