The Muzzleloader

Our Muzzleloader is a game changer for your hunt, and possibly some hunting regulations.

Realistic one MOA groups at 500 yards are attainable with a system that offers easy loading with sabots, and over 1600 fps of impact velocity using a 325 grain bullet. We found that heavy recoil is the number one issue with other muzzleloaders, so we focused on stock design, weight, balance, and correct muzzle brake design to tame the heavy muzzle loader recoil. Still, as a hunting rifle, an overall weight under eight pounds can be achieved with the right configuration.  

The Muzzle Loader secures primacy in the pursuit of the one shot kill.

The System

The Muzzleloader is the most challenging configuration Gunwerks produces. Accurate shots from a muzzle loader at 500 yards require every component of this long range system to function perfectly. Bore conditioning, load development, and ballistic profiling all require more effort and expertise - on our part. Depending on your requirements, we can set the system up with open sights or a long range scope with a calibrated ballistic turret.

The Design

Creating a muzzle loader that can shoot long range is a challenge, but adding the requirements of easy loading, low recoil, and low maintenance drives the engineers crazy. Engineering is a balancing act of managing trade offs. For example, increasing the BC requires more weight and a faster twist rate, however the sabot can’t handle the stress from a heavier bullet and faster twist. Finding the best balance is the test.

The Hunt

We developed the Muzzle Loader as a tool for chasing the biggest animals during special seasons for “primitive” weapons. We apply for tags in Iowa, Kansas, New Mexico, Colorado, Utah, and Nevada every year with hopes of drawing a tag for monster elk and deer. If we apply for the muzzle loader seasons our odds go up dramatically. When we draw the tag, the muzzle loader makes sure we put a trophy on the wall and meat in the freezer.

Ballistic Turret

We developed a true 1X scope and a ballistic turret specifically for some states' regulations. If you calibrate a custom turret for the 1X or our standard 5.5-22, you will get 500 yards of correction in one turn of the elevation turret.

LRM500 Action

The LRM500 action features a simple rear locking bolt and 209 primer holder. The bolt cycles like a standard rifle, and the spent primers remove easy with a flick of the finger.

Rifle Stock

Recoil is a big factor with high performance muzzle loaders. There is not a lot you can do. However, you can reduce the felt recoil by using the LR1000 stock with its negative comb and other recoil reducing features.


Our breech plug is removable with a simple socket wrench. Its easy to clean or maintain, and it utilizes a standard 209 style primer.  


If needed, we offer a unique open sight with a ballistic scale for precise shots to 300 yards and beyond. The adjustable globe sight up front doubles as a ramrod holder.

Bullet BC is really important with the slower muzzle velocity of a muzzle loader. Our preferred bullet has a 0.420 effective BC for downrange performance to 500 yards. We load it in a special sabot and fast twist 1:22 barrel for easy loading and proper bullet stabilization.

CNC MFG/ Engineering

Long range shooting requires precision. Our Engineering, Manufacturing, and Quality Control Process gives us a distinct advantage over the small boutique rifle builder. We can give our customers a better product.

Once In a Lifetime

Pinpoint Accuracy

I was able to draw a once in a lifetime mountain goat tag in Utah. I knew making an accurate shot with any muzzleloader would be difficult with a one powered scope. You need to have pinpoint accuracy. After shooting this muzzleloader at the range I had all the confidence I needed to shoot any animal up to 300 yards. I made a perfect shot at 185 yards. Thanks to Gunwerks I was successful.

Complete Confidence

Got my muzzleloader for the whitetail woods of the South. First hunt with it was an absolute success as I harvested a great Kentucky whitetail. Complete confidence in the performance of my muzzleloader!

My Best Whitetail

I purchased my muzzleloader for hunting big whitetails on my lease in Iowa. I needed to be as confident with it as I am with my LR 1000. My first hunt with it enabled me to take a 174 5/8 whitetail at over 200 yards. Now that's confidence!
