Hornady MonoFlex (45010) component bullets give reloaders the ultimate lever-action hunting bullet for 45-70 Government and compatible 45 caliber rifle cartridges, combining monolithic copper alloy construction with a patented Flex Tip design for deep penetration, maximum weight retention, and tubular magazine safety in one purpose-built projectile. These 45 caliber .458 diameter 250 grain MonoFlex bullets pack 50 per box and are the top reloading component for lever-action hunters pursuing medium to large game who need a lead-free, non-separating bullet that expands reliably at the lower velocities mid-to-long range lever gun shooting produces.

Special Features
- Patented Flex Tip technology uses a soft polymer tip that compresses into the bullet cavity on impact, initiating immediate and consistent expansion even at the lower velocities typical of mid-to-long range lever-action shooting where standard hollow points often fail to open.
- Tubular magazine safe design makes this bullet a direct fit for lever-action rifles and carbines where a pointed metal tip is unsafe to stack in a tube magazine, solving the single biggest limitation lever-action hunters face when trying to run a tipped bullet.
- Monolithic one-piece copper alloy construction delivers 95 percent weight retention on recovery, driving straight and deep through heavy bone and dense muscle without shedding mass the way jacketed lead-core bullets can.
- Copper alloy differs from solid copper in that it is harder, tougher, and does not foul bores or spike pressure the way pure copper bullets can, making it easier to load and shoot across extended range sessions.
- Ballistically efficient secant ogive profile produces a higher ballistic coefficient than flat point designs in the same caliber, delivering flatter trajectories and greater downrange energy from lever-action rifles.
Practical Benefits
- Lever-action hunters running 45-70 Government rifles for elk, bear, bison, and other large game get a bullet that combines the penetration of a monolithic solid with the expansion reliability of a tipped hollow point, a combination no flat point or standard cup-and-core bullet delivers.
- The lead-free copper alloy construction makes the Hornady MonoFlex (45010) the right fit for hunters required to use non-toxic ammunition, with no performance trade-off compared to traditional jacketed bullets.
- Reloaders developing 45-70 loads for both close-range and longer-distance hunting scenarios get a bullet that performs consistently across that entire velocity spread, from full-power muzzle velocities down through the reduced speeds at extended range.
- Your handloads built on the Hornady MonoFlex (45010) give you a lever-action hunting bullet that is tubular magazine safe, lead-free, and built to drive through the toughest game animals you will encounter in the field.
The Hornady MonoFlex (45010), a 45 caliber .458 diameter 250 grain monolithic polymer-tipped bullet, is a proven platform and confident choice for lever-action hunters who demand deep penetration, maximum weight retention, and reliable expansion in 45-70 Government hunting loads.
