These guys must have really good liability insurance.
These loads are safe in all large frame Ruger revolvers, TC Contender, Colt Anaconda, and Freedom Arms firearms. These loads are safe in all modern Model 1892 leverguns as well as all Winchester & Marlin 1894’s. DO NOT USE IN ANY OTHER FIREARM. THESE ARE NOT STANDARD PRESSURE CARTRIDGES! Do not use +P ammunition in firearms that are replicas of early designs, such as rolling blocks, Sharps and Colt-style single action army revolvers.
Underwood Ammo combines our trademark power and precision with Lehigh Defense’s masterfully designed Xtreme Penetrator bullets–the result is one jaw dropping round. This round is solid copper and features a unique nose that maximizes penetration and facilitates consistent and reliable magazine feeding.
We do not use the industry wide duplicitous practice of obtaining our advertised velocities out of extra long laboratory barrels, which give super high velocities the customer will never realize in the real world, where it actually matters.
âž¤ Â Â 1890 fps –Â Marlin 1894, 20 inch
âž¤ Â Â 1526 fps –Â Ruger Vaquero LARGE FRAME PRE 2006, 5.5 inch
âž¤ Â Â 1539 fps –Â Freedom Arms mod. 97, 5.25 inch
âž¤ Â Â 1449 fps –Â Ruger Redhawk, 4 inch
You’ll notice in one instance that a shorter barrel gave higher velocities than a longer barrel. This is not a typo.
This load is designed as the world’s premier deer load for the 45 Colt +P. The cast bullet is not considered hard, but neither is it soft. It is essentially a “medium” cast hardness with a BHN (Brinell Hardness Number) of 12. Pure lead is 4 and most hard cast bullets range from 15 to 25. It performs as follows:
â—¼ï¸Ž Â At an impact velocity of 1,100 fps it will mushroom to about 80 cal. and should push right through any deer with a broadside shot. Â
â—¼ï¸ŽÂ Â At an impact velocity of 1,500 fps it will mushroom and some of the mushroom will fragment off and send bullet particles flying through the deer, but much of the mushroom and shank will remain intact and should push through any deer hit broadside.
â—¼ï¸ŽÂ Â At an impact velocity of 1,900 fps the entire mushroom will turn to shrapnel and send bullet particles all throughout the deer. The shank will remain intact, but will re-mushroom and do horrific damage inside the deer and will probably push through any deer hit broadside.
Of course, results will vary depending on how much bone, if any, is hit, etc… This load was designed specifically to do horrific damage to deer sized animals such as average black bear and hogs. It will make an incredible anti-personnel load if you can handle the recoil. It is flash suppressed and will not blind the shooter if used in low light when the criminal element and wild animals are most active.
The cartridge OAL is 1.585 inch and as such will chamber in any 45 colt firearm such as the Colt SAA or its clones, but firing this +P load in any firearm not designed for it would be disastrous, and could injure the shooter or bystanders. Please be responsible and use this load only in firearms designed to handle the pressure of +P ammunition.
Use only in the following firearms:
1. Â All Ruger large frame revolvers chambered in 45 colt or 454 Casull. (never use +P ammo in the small frame New Model Vaquero–these revolvers were made from late 2006 and on–do not use in the New Model small frame Flat Top Ruger or ANY small frame Ruger)
2. Â All 1892 Winchesters and all copies of such made after 1920.
3. Â All Winchester and Marlin 1894 models.
4. Â Any break open action such as the T/C or Handi Rifle.
5. Â Any falling block action such as the Sharps or Winchester 1895.
6. Â Any Freedom Arms model 83 or 97.
7. Â Henry Big Boy .45 Colt
