I have shot sw 250gr bonded out of my optima elite for a few years without any problems. They are very accurate out of my rifle. I have only shot 3 deer with them and all preformed just fine, however its hard to judge a bullet on just 3 game animals. The bonded sw should not have any problems with bullet seperation since they are bonded. I use this rifle when I hunt in fields with the chance of a longer shot.
