vette447,
Full disclosure: I am one of the sales managers at Magtech USA. CBC/Magtech owns S&B. 7x57 is one of my favorite calibers. (Ruger No 1 Boddington). While everyone has their favorite brand, caliber, bullet, etc, I take issue with the above comments regarding our quality. Of course, not every brand of ammunition is a good match for every rifle, but S&B manufactures ammunition to the highest performance standards for very demanding customers such as NATO countries, various Military customers worldwide, Law Enforcement agencies worldwide (many of which are in No Europe, Germany and Austria) and numerous firearms manufacturers. If your ammunition doesn't perform, you don't receive an invitation to bid on these contracts. These customers do not choose their ammo based on cost alone. Not far from Prague, we operate one of the most modern ammunition factories in the world. We've been in business since 1825 at the same location. I can assure you that high cost does not necessarily equate to better ammunition.
The SPCE bullet, while accurate, is not constructed with tough, heavy duty game animals in mind. I use it when hunting animals in the whitetail deer class at closer range. For tough animals, I would suggest you try either our 175gr Nosler Partition load or the 158gr Exergy bullet load. The Exergy projectile is our proprietary expanding copper bullet. The Partition has a higher BC and a great history of performance, but the Exergy will retain more of its weight. Both are excellent. Shoot whichever is more accurate in your rifle.
Take care,
Tango
