I have no personal experience with the contract S&B but used to shoot a lot of the S&B in other guns especially a 9X18 Makarov that ate a bunch of it.
I always found S&B to be warm ammo but always functioned well.
Just for interest, this is what SGAMMO says about the RUAG:
1000 round case of 9mm Luger 124 grain FMJ European government contract ammo. Boxer primer, non-corrosive, non-magnetic. Made for Sellier Bellot under contract by Ruag in Germany. The story on this ammo is that Sellier & Bellot won a contract for the EU government but had a lot of the ammo manufacturing sourced out to Ruag in Germany. This is why the ammo is branded as sellier bellot, but made in Germany rather than the regular S&B Czech factory. This is the overrun ammo left over from that EU government contract at a discount price. High quality brass case target ammo, standard pressure, non-magnetic copper jacket. Great for all purpose shooting / training.
