The .308 Subsonic Controlled Fracturing was designed for outstanding terminal subsonic performance for suppressed bolt gun or single shot applications. The required barrel twist rate for stability with a muzzle velocity of 1,050 fps is 1:8. Testing has shown terminal performance is dramatically improved by inserting a .17 caliber payload bullet (not included) into the hollowpoint cavity. The hollowpoint was designed with a light .172 slip fit and the payload bullet can be retained with a small amount of epoxy. A 20 grain Berger appears to improve terminal performance over a 25 grain Hornady. The function of the payload bullet is to shift the cg forward and to direct the hydrostatic energy outwards accelerating the expansion. Weight - 150 grains (without payload bullet) BC G1 1,050 fps (calculated) - X.XXX Length - 1.235 Design velocity - 1,050 Material - UNSC36000 brass Sold in a packages of 50 at $60.00/box. Shipping via USPS Priorty Mail to the 50 states is included in the price.

The .375 Subsonic Controlled Fracturing was designed for outstanding terminal subsonic performance for suppressed bolt gun or single shot applications. The required barrel twist rate for stability with a muzzle velocity of 1,050 fps is 1:8. Testing has shown terminal performance is dramatically improved by inserting a .22 caliber payload bullet (not included) into the hollowpoint cavity. The hollowpoint was designed with a light .224 slip fit and the payload bullet can be retained with a small amount of epoxy. A payload bullet that extends less than .100 from the nose is preferred. The function of the payload bullet is to shift the cg forward and to direct the hydrostatic energy outwards accelerating the expansion. Weight - 310 grains (without payload bullet) BC G1 1,050 fps (calculated) - X.XXX Length - 1.725 Design velocity - 1,050 Material - UNSC36000 brass Sold in a packages of 50 at $XX.XX/box. Shipping via USPS Priorty Mail to the 50 states is included in the price.

The .458 Match Subsonic is a premium match bullet specifically designed for extreme range subsonic applications. There may also be high velocity applications as well, but at this point testing has not been done. The required barrel twist rate for stability with a muzzle velocity of 1,050 fps is 1:10. Weight - 582 grains BC G1 1,000 fps (calculated) - 0.629 /// BC G1 3,000 fps (calculated) - 1.105 Length - 2.414 Design velocity - 1,050 Material - UNSC36000 brass Sold in a packages of 50 at $90.00/box. Shipping via USPS Priorty Mail to the 50 states is included in the price.

The .458 Subsonic Controlled Fracturing was designed for outstanding terminal subsonic performance for suppressed bolt gun or single shot applications. The required barrel twist rate for stability with a muzzle velocity of 1,050 fps is 1:10. Testing has shown terminal performance is dramatically improved by inserting a .224 diameter payload bullet (not included) into the hollowpoint cavity. The hollowpoint was designed with a light .224 slip fit and the payload bullet can be retained with a small amount of epoxy. The payload bullet can be any manufacture with a weight equal to or greater than 50 grains. The function of the payload bullet is to shift the cg forward and to direct the hydrostatic energy outwards accelerating the expansion. Weight - 528 grains BC G1 1,050 fps (calculated) - 0.915 Length - 1.950 Design velocity - 1,050 Material - UNSC36000 brass Sold in a packages of 50 at $100.00/box. Shipping via USPS Priorty Mail to the 50 states is included in the price.

The .510 Subsonic Controlled Fracturing was designed for outstanding terminal subsonic performance for suppressed bolt gun or single shot applications. The required barrel twist rate for stability with a muzzle velocity of 1,050 fps is 1:10. Testing has shown terminal performance is dramatically improved by inserting a .243 diameter payload bullet (not included) into the hollowpoint cavity. The hollowpoint was designed with a light .243 slip fit and the payload bullet can be retained with a small amount of epoxy. A payload bullet should be selected that does not extend greater than .100 out of the nose. The function of the payload bullet is to shift the cg forward and to direct the hydrostatic energy outwards accelerating the expansion. Weight - 639 grains (without payload bullet) BC G1 1,050 fps (calculated) - X.XXX Length - 2.000 Design velocity - 1,050 Material - UNSC36000 brass Sold in a packages of 50 at $110.00/box.
