Petanque Boule Match Soft Upsilon

How to choose the right boules

The boules are first chosen according to your hand size (diameter).

then based on weight (heavier for pointers and lighter for shooters), then based on elasticity (hard, semi-soft or soft boule), then handling feel.

How are boules manufactured?

Match boules are hollowed out:

a lump of steel is heated up to 1800°F and flattened, then embossed to make a half sphere.

The half spheres are welded, then turned to form perfect cylinder shape, then stamped.

The boule is subsequently heated, and then steeped in baths to determine its hardness.

It is then polished or varnished before inspection.

What does hardness mean?

The standard way to express boules hardness is based on ROCKWELL "HRC" index, or in lbs/sqmm.

For example, 39 HRC corresponds to 273 lbs/sqmm. The higher the number, the harder the boule.

The harder the boule, the less likely it is to get damaged and the higher its elasticity.
