Hi-Lux Optics Off-Set Plates w/ 1/2in 60 Degree Base Review

The One Thing I Didn’t Expect from the Hi-Lux Optics Off-Set Plates w/ 1/2in 60 Degree Base

My quest for a better mounting solution for my vintage muzzleloader’s optic led me to the Hi-Lux Optics Off-Set Plates w/ 1/2in 60 Degree Base. For years, I’d grappled with the classic dilemma of fitting a modern scope onto an antique firearm, specifically a percussion rifle with a side hammer. The core issue is clearance: ensuring the hammer can cycle without colliding with the scope tube, and critically, that the scope is positioned for a natural shooting stance. This particular set of bases promised to solve that very problem, offering a specific offset geometry designed for just this purpose.

The need arose after I acquired a beautifully restored, octagonal-barreled percussion rifle. While a joy to shoot, attempting to mount even the slenderest of scope options proved frustrating. Standard mounts pushed the scope too far forward or backward, compromising eye relief or, more alarmingly, threatening interference with the hammer. I’d looked at custom solutions and even considered modifying existing mounts, but nothing felt quite right or cost-effective. This Hi-Lux offering, specifically designed for this niche, immediately caught my eye as a potentially elegant solution.

My initial impression upon unboxing these offset plates was one of sturdy simplicity. They are crafted from what feels like solid steel, with a consistent matte black finish that suggests durability. The machining appears precise, with clean edges and well-defined screw holes. Unlike some flimsy alternatives I’ve encountered in the past, these bases exude a no-nonsense, functional quality. They feel like they were made to be bolted onto a rifle and endure regular use.

I briefly considered universal base sets, but the specific mention of “60 Degree Base” and the intended application with Malcolm-style scopes on side-hammer rifles narrowed my focus. It’s rare to find a component so thoughtfully tailored for such a specific, albeit classic, firearm type. The immediate reaction was a sense of cautious optimism, a feeling that the core problem might finally have a straightforward answer.


Real-World Testing: Putting Hi-Lux Optics Off-Set Plates w/ 1/2in 60 Degree Base to the Test

First Use Experience

My testing grounds were straightforward: the workbench and then, crucially, the shooting bench with my chosen percussion muzzleloader. The scenario involved mounting a 17-inch, 3x Malcolm-style scope. The process was uncomplicated; I aligned the bases on the octagonal barrel’s flat top, ensuring the offset would provide adequate hammer clearance and the best possible eye relief. The Hi-Lux Optics Off-Set Plates w/ 1/2in 60 Degree Base accepted two scope rings for a 0.75-inch tube diameter, fitting my chosen optic perfectly.

The plates themselves are designed to be attached with either two or three screws, depending on the barrel’s contour and anticipated recoil. My barrel had ample flat surface, so I opted for the three-screw configuration for maximum stability. Installation was a matter of careful alignment and secure fastening with appropriate hardware (screws not included, a minor point for consideration). Once mounted, the plates provided a stable platform for the scope rings, and the offset was immediately apparent. It shifted the scope’s position just enough to clear the hammer without forcing an unnatural head position.

I did encounter a slight learning curve in determining the optimal fore-aft positioning for the scope. This isn’t a flaw of the bases themselves, but rather an inherent aspect of scope mounting. The Hi-Lux Optics Off-Set Plates w/ 1/2in 60 Degree Base provide the mechanism for the offset, but the shooter still needs to find the sweet spot for eye relief. This involved loosening the scope rings slightly and sliding the scope fore and aft until a comfortable and consistent sight picture was achieved. This adjustment process was straightforward thanks to the secure, yet adjustable, nature of the Malcolm scope rings.

Extended Use & Reliability

After several range sessions and more than a dozen trips to the field with this rifle, the offset plates have proven their worth. They continue to hold the scope securely, with no hint of shifting or loosening, even under the moderate recoil of .50 caliber percussion loads. The matte black finish has held up well, showing only minor cosmetic scuffs where I might have inadvertently bumped them against something, but no signs of rust or significant wear.

Maintenance has been virtually non-existent, which is exactly what I want in a rifle accessory. A quick wipe-down with a cloth to remove dust or powder residue is all that’s needed. The steel construction feels robust enough to handle accidental drops or impacts that might occur in a field environment, though I haven’t intentionally subjected them to extreme abuse. Compared to the flimsy, bent metal mounts I’ve sometimes seen used on similar builds, these Hi-Lux plates offer a level of reliability that instills confidence. They simply perform their intended function without fuss.

The One Thing I Didn’t Expect from the Lyman Pistol Bullet Mould: 45 Colt – #452424 2660422

For a decade now, my hands have been stained with lead, my workbench perpetually dusted with graphite, and my ears tuned to the distinct thwack of a well-cast bullet hitting its mark. As an avid shooter and reloader, I’ve explored a vast landscape of bullet molds, each promising perfection, some delivering, others falling by the wayside. My search for the definitive 45 Colt bullet, one that embodied the spirit of the Old West while performing with modern precision, eventually led me to the Lyman Pistol Bullet Mould: 45 Colt – #452424 2660422. Lyman, a name synonymous with reloading excellence, and a mold specifically designed by the legendary Elmer Keith – it was a combination that whispered of unparalleled performance and historical significance.

My quest began with a simple desire: to replicate the legendary performance of the 45 Colt with a bullet that truly honored its heritage. I wanted a projectile that would feed flawlessly, shoot accurately, and hold up to the demands of both the target range and the occasional backcountry excursion. Over the years, I’d experimented with various designs, but none quite captured the essence of what I envisioned. The allure of the #452424, with its semi-wadcutter (SWC) profile and the backing of Elmer Keith’s design philosophy, was undeniable. It promised a bullet that would cut a clean hole in paper and deliver a solid punch in any application.

Unboxing the Lyman Pistol Bullet Mould: 45 Colt – #452424 2660422 was a familiar ritual, yet tinged with anticipation. The heft of the machined iron felt substantial, reassuring. The mold halves fit together with a satisfying precision fit, a testament to Lyman’s manufacturing prowess. The cavities, a deep, lustrous grey, were perfectly formed, showing no signs of porosity or imperfections. The sprue plate moved smoothly, and the alignment pins felt robust. It was clear this wasn’t just a tool; it was a piece of reloading artistry, built to last generations.

I’d previously tinkered with other Lyman molds and some of their competitors. While many produced good bullets, the Keith design for the #452424 stood out in its conceptual elegance. The choice between a round nose or a flat-nosed bullet often boils down to feeding characteristics and terminal performance. The SWC profile of the #452424 offered a compelling compromise, promising good feeding with an effective meplat for energy transfer. This particular mold, the double cavity version (2660422), meant I could cast two bullets at a time, significantly increasing production speed over single-cavity molds.

Real-World Testing: Putting Lyman Pistol Bullet Mould: 45 Colt – #452424 2660422 to the Test

First Use Experience

My first casting session with the Lyman Pistol Bullet Mould: 45 Colt – #452424 2660422 took place on a crisp autumn afternoon, the scent of burning leaves mingling with the metallic tang of molten lead. I set up my pot and heater in the familiar chaos of my outdoor casting area, where the elements are less of a concern. The mold, pre-heated to a uniform temperature, received its first pour of a 50/50 alloy (lead and tin), seasoned with a touch of tin for better fill. The molten metal flowed beautifully into the double cavities, filling every detail of the semi-wadcutter design with remarkable ease.

As I worked the sprue plate and ejected the freshly cast bullets, I was struck by the impeccable detail of the #452424 design. The clean shoulder of the SWC, the distinct grease grooves, and the precisely formed meplat were all present and accounted for. There was minimal lead splash, a sign of a well-fitted mold. The resulting bullets, weighing in at a consistent 255 grains (as advertised), were remarkably uniform. I experienced no difficulty with the required double cavity handles, which provided a comfortable and secure grip.

The true test, however, came at the range. I loaded these cast bullets into Starline brass, using a moderate charge of Accurate Arms #9 powder, carefully metered to a proven load. My chosen platform for this test was a Ruger New Vaquero in .45 Colt, a trusty companion for many years. As I settled into my shooting stance, I cycled through the cylinder, noting the smooth action and the solid feel of the hand-cast bullets seating into the chambers. The first shot rang out with a satisfying report, and the bullet struck true.

Subsequent shots confirmed what I suspected from the initial casting: this mold produces exceptionally accurate bullets. The semi-wadcutter profile of the #452424 seemed to glide through the forcing cone and barrel, delivering tight groups at 25 yards. The larger meplat created satisfyingly round holes in the paper target, making sight alignment and scorekeeping a breeze. I tested the mold in conditions ranging from a mild spring day to a slightly humid summer afternoon, and the performance remained consistently excellent. The only real surprise was just how easy it was to achieve such high levels of accuracy with a relatively simple bullet design.

The durability of the cast iron construction is evident; despite constant heating and cooling cycles, and the occasional accidental tap against my bench, the mold shows no signs of wear that would affect its performance. The machined surfaces remain smooth, and the alignment pins are still snug.

Maintenance is refreshingly straightforward. A quick wipe-down with a soft cloth after each casting session, and an occasional light application of mold release, keeps it in prime condition. I’ve found that using a good quality alloy, such as the 50/50 mix or even a slightly harder alloy like WW (wheel weights) with a bit of tin, ensures the best results and makes the bullets easier to size and load. The sizing process itself has been a pleasure; the #452424 bullets, when cast and sized to .452 inches, drop into my cases with minimal effort, and the crimp is secure.

Compared to other molds I’ve used in the past, the Lyman Pistol Bullet Mould: 45 Colt – #452424 2660422 consistently outperforms them in terms of ease of use and bullet quality. I’ve had other molds that required extensive lapping or constant fiddling to achieve decent results, but this Lyman mold has been a revelation in its unwavering reliability. It’s the kind of tool that you can depend on, time after time, to deliver exactly what you need. It has certainly outperformed my earlier experiences with less expensive or less robust molds.

Breaking Down the Features of Lyman Pistol Bullet Mould: 45 Colt – #452424 2660422

Specifications

The Lyman Pistol Bullet Mould: 45 Colt – #452424 2660422 is a finely crafted piece of reloading equipment designed for the serious handloader. Its primary specification is its caliber designation, specifically for the venerated .45 Colt cartridge. The bullet weight is a substantial 255 grain, a classic weight for this caliber that balances energy transfer with manageable recoil.

This mold features a double cavity design, identified by the product number 2660422, which significantly speeds up the casting process. The top punch number is 424, corresponding to the specific shape of the bullet nose. Crucially, the mold requires double cavity handles, sold separately, to operate. The bullet profile is a Semi-Wadcutter (SWC), characterized by its flat nose and distinct shoulder.

The mold is designed to produce bullets that, when sized, will fit various .45 Colt firearms. The recommended sizing dies are .451 and .452 inches. This range allows for flexibility depending on your specific firearm’s chamber and bore dimensions, ensuring a proper fit for optimal accuracy and feeding. The use of machined iron for the mold itself is a key material specification, providing excellent heat retention and durability.

These specifications are not mere numbers; they translate directly into user experience and performance. The 255 grain weight, coupled with the SWC profile, is a well-established combination for effective energy transfer and clean-edged bullet holes.
