pharaoh2, I have found the 99 to be particular about what they will shoot well.I did a lot of load testing before I got a couple of good loads for both of mine. My 250 will shoot the 85 gr bt with H380 handload and the 100 gr winchester silvertip factory load into 1 moa and my 284 will shoot the 139gr hornady into 1 moa while the 154 gr hornady round nose into 1 1/4 inches using H4350
