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. The LAZER line can be used at all ELR ranges. 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 function down to 1400fps. Required twist rate for this bullet is 1:10 or faster. *If shooting through transonic, a twist rate increase of 1 inch is recommended (ex: 1:9 instead of 1:10) Technical Info: Caliber: .308 Weight: 180 grains Required Twist Rate: 1:10 or faster G1 Ballistic Coefficient: .525 G7 Ballistic Coefficient: .269 OAL: 1.537 Projection Length: .750 Min Impact Velocity Required for Expansion: 1400fps
