Over the years, we have mounted just about every make and model scope on our muzzleloaders in a quest to find the perfect ML scope. We think that we have finally found it. The Toby Bridges Signature Series, TB-ML3-9x40 scope by Hi-Lux. It arrived last month and when we looked through the eyepiece, we were astounded. It was so clear and the focus was so phenomenal that we were hard pressed to believe that such a scope was possible for the price. We compared it side-by-side with our NXS Nightforce tactical scope, which cost $1,800, and it was just as good. The edges of the viewing field were just as sharp as the center. Mr. John Wu, the head man at Leatherwood Hi-Lux, was not exaggerating when told us that he will not settle for second best.

Since researching Hi-Lux riflescopes and testing the TB-ML scope, we have found out one reason why the optics are so clear. The lenses are polished to photographic quality standards, the same as those found in high-end cameras and telescopes.

Toby bridges, the designer of this scope, has been a muzzleloader hunter for more years than we can count. He is the first and only man to design a scope specifically for muzzleloaders, with range crossbars below the primary crosshair to provide an accurate point-of-impact for ranges out to 250 yards. Unlike conventional scopes with similar crossbars or mil dots, Toby and the folks at Hi-Lux fired more than 1,000 rounds using different loads/bullets to compile the ballistics charts included with the scope.

We considered it unnecessary to verify the ballistics charts, since we have known Toby for quite awhile and respect his efforts and findings. However, we know that some readers would question our taking the charts at face value. Therfore, Jim hit the local range and fired over one hundred rounds with his new CVA Optima V2 using Blackhorn 209 powder, Alliant Black MZ powder, Hodgdon Triple7 pellets and IMR White Hots pellets.  He used Crush Rib sabots with 260 grain Harvester Scorpion PT Gold and 250 grain "Powerbelt" Aerolite bullets.

Jim didn't have to fire 1,000 rounds to confirm that the Bridges/Hi-Lux charts are accurate. Even if you don't have a chronograph to check your loads, you can closely approximate the velocities using load data provided by Toby. Talk about someone doing your homework, they did!

One of the tables included with the scope is reprinted below. It is for hunters using three of the most popular spitzer or spire point bullets with sabots, as well as CVA's Aerolite bullet. Our range test confirmations have been inserted for reference in italicized capital letters. You will want to verify the crossbar distances for your gun on the range before heading out to hunt, as your velocities may be higher or lower due to the working bore of your gun. rom The Hi-Lux Optics TB-ML Owners Manual:
