If you've spent any amount of time around steel mace training, you've probably heard the terms 300 and 10 to 2 used almost interchangeably.
For years, we thought of them as essentially the same movement. They both involve swinging the mace from one side to the other without completing a full 360, and most people would understand exactly what you mean regardless of which name you use.
But after watching a discussion from The Flowing Dutchman and spending some time thinking about it ourselves, we realized there's actually a subtle distinction that's worth understanding.
Not because one movement is better than the other.
But because understanding movement makes you a better athlete.
Why They're Called Different Things
The biggest clue is right in the names.
A 10-2 references the face of a clock. Imagine the mace traveling between the 10 o'clock and 2 o'clock positions before changing direction.
A 300, on the other hand, refers to degrees of rotation.
When you actually compare those two ideas, they don't perfectly match.
A true 300 degree movement ends up being more vertical – closer to what might look like an 11 to 1 path instead of the wider 10 to 2 arc many of us naturally perform.
It's a small difference on paper.
In practice, it changes the feel of the movement quite a bit.
The Path of the Mace Matters
Traditional 300s are often demonstrated by bringing the handle over the shoulder so the mace head comes much closer to the side of the head.
Many practitioners refer to this as a shoulder drag.
With a 10 to 2, the handle typically travels farther across the front of the shoulder before reversing direction.
That slightly wider arc creates a different loading pattern and a different feel throughout the swing.
Neither is wrong.
They're simply different movement patterns.
Where We Tend to Train
Personally, we spend much more time performing what we'd call a traditional 10 to 2.
Why?
Because the tension throughout the movement feels incredibly consistent.
As the mace approaches the end of the arc, we can still feel it pulling away from us, allowing us to immediately cast it back in the opposite direction.
When we bring the mace much closer to the head—as in a true 300—the leverage begins to change.
You can actually feel the weight start to "cam over," where the momentum shifts and the mace begins pulling in the opposite direction.
Some athletes enjoy that feeling.
Others prefer maintaining continuous tension throughout the entire pattern.
Neither approach is objectively superior.
They're simply different tools.
Film Yourself
One of the biggest takeaways from this discussion is how valuable video can be.
Sometimes we think we're performing a movement one way until we actually watch ourselves.
That was the case here.
After reviewing video, it became obvious that our own swings naturally stayed much closer to a 10 to 2 than a traditional 300.
Video doesn't lie.
Whether you're learning mills, 360s, pendulums, or 10 to 2s, recording yourself is one of the fastest ways to improve technique.
Do the Names Really Matter?
Honestly?
Not much.
Outside of very specific coaching situations or formal competitions, very few people are going to criticize you for calling one movement by the other name.
The steel mace community has always been about learning, experimenting, and sharing ideas.
The important part isn't memorizing terminology.
It's understanding why movements feel different and recognizing that even small changes in lever angle can completely change the training stimulus.
Keep Learning
One of the best parts of steel mace training is that there's always another layer to uncover.
The longer we've been training, the more we've realized there are endless nuances in grip, leverage, body position, timing, breathing, and movement quality.
That's what keeps it interesting.
Whether you call them 300s or 10 to 2s, keep swinging, keep experimenting, and keep learning.
You never know what small detail will unlock a completely new understanding of the movement.
