Reloading Blocks Explained
If you’ve been reloading long enough, you’ve probably noticed an odd mismatch in the hobby: we’ll invest in match-grade dies, premium powders and thousand-dollar optics… then trust our cases to cheap reloading blocks that cost three bucks at a gun show in 2004. It’s one of the most touched tools on the bench, yet it’s rarely upgraded until something goes wrong. And when a block or other method of handling your cases fails — wobbling brass, tipping cartridges, or outright powder dumping — you feel it.
But why use a reloading block? What kind of reloading block should you get? There are a few options out there.
Case Handling Background & History
Reloading blocks hold 20-100+ cases with the most common size being 50 rounds. Handloaders use these blocks to store brass cases and even bullets during the loading process as they process their brass and prepare their cases for reloading. Typically the blocks hold only one size of case head, which gives a tight, secure fit on a case but only on one caliber family. For example, a block sized for .308 will hold cartridges such as .308 Winchester, and .30-06 Springfield, but will be too big for a tight fit on cartridges like .223 Remington and 22 Creedmoor, as well as too small for .338 Lapua.
Today’s most common type of plastic reloading blocks came into being the 1960s and 1970s. Historically before this period, handloaders made their own blocks from wood. Others went without blocks at all and put up with the inaccuracies and even safety issues of setting charged cases on their bench top.
RCBS and other manufacturers began offering universal or multi cartridge plastic case blocks as time went on. In recent years, tool manufacturers began machining aluminum or even steel blocks as way to provide more durable, stable blocks that did not shift around on a bench top.
Today’s Approach
Today’s reloaders are working across more cartridges than ever. You might size .223 Remington on a weeknight for plinking, prep 6mm Creedmoor brass for a weekend match, and then switch back to .22-250 varmint rounds during the spring. Traditional plastic, wood or even most modern aluminum single-caliber blocks force you to keep a stack of different sizes on hand — and they all take up space.
Anyone who’s used budget blocks knows the pain points:
- Plastic wears out, gets loose, and builds static. Budget friendly but disposable
- Cheap aluminum blocks vary wildly in pocket depth and finish and hold only one size of case head
- Caliber-specific blocks pile up, especially for multi-gun shooters
- Inconsistent machining leads to wobble, especially with long or heavy brass
These sound like small issues — until they interrupt your flow or compromise your confidence when handling charged cases. Reloading works best when nothing feels uncertain. That includes the block beneath your brass.
RCBS MatchMaster Approach
RCBS’s MatchMaster line is known for precision and refinement, and now includes a premium reloading block that solves these issues. Here’s what stands out about the Match-Master Multi-Cartridge Reloading block:
✔ Premium CNC-Machined Aluminum
No rough edges. No shallow spots. No pockets that vary from row to row. Each hole is cut with exacting tolerances so brass sits consistently and securely every time, with a block weight and specially designed feet that keeps everything steady and sturdy on your bench
✔ Dual-Caliber Versatility
Both .223 and .308 hole patterns are machined into the same side — a layout that keeps the block compact, intuitive, and bench-friendly, while allowing for a host of calibers to fit
✔ True MatchMaster Fit & Feel
The block has a satisfying weight, a clean anodized finish, and the kind of solid stability that gives you confidence when handling charged brass. It feels like a tool built for serious reloaders.
✔ Smart 50-Round Capacity
Enough for large prep sessions, small-batch precision work, and everything in between. The layout is deliberate, spacious, and easy to navigate without bumping cartridges.
Why a Better Reloading Block Actually Matters
Reloading isn’t just a mechanical process — it’s a rhythm. How your tools are arranged, how they feel in your hands, and how smoothly they work together all shape the quality of your rounds.
A premium block supports:
- More efficient charging sequences
• Faster transitions between stations
• Cleaner organization during brass prep
• Safer handling of powder-filled cases - A larger assortment of cartridges held
When you eliminate the tiny frustrations — the wobbles, the clutter, the mismatch of blocks — the whole experience improves.
It’s not about making your ammo magically better. It’s about making you more consistent.
Sometimes the most meaningful improvements come from the simplest pieces of gear — especially when they’re designed like they matter.
