That's a. French company. They started by making their own all coper fragmented bullets,The GPA (Grande puissance d'arret = big stopping power).
Very similar to the cutting edge bullets.
Then, they also produce their own manufactured ammunition in several calibers, including very specific and big bore with bullets from Nosler, Barnes, Hornady, woodleigh, etc.
THeir ammuition is very good. THey are quite conservative in their load (in the sense that their goal is not to create as much fps as possible). Their advertised FPS are very close to measured velocities.
They are quite pricey, but ammo is a lot more expensive in Europe than in the US.
In their catalog the colomn with "la boite 20" (20 rounds box) is the price in Euro.
You can find them easily in France, Germany, Switzerland, Spain, Italy.
I hunted with their 338 lapua Nosler partition, 458 Lott 480gr Woodleigh - very happy
Labor fur ballisitc and sax ammunition are also alternative of small ammo manufacturer in Europe.
