I shoot Barnes Expanders 250 grain out of my Knight Wolverine with excellent results but they load too hard in the Black Diamond XR. I like the 357 grain Buffalo Bullet SSB sabot in the Black Diamond. I get them at Cabela's. Triple Se7en suggested them and they have been working great. Easy to load and excellent accuracy with 100 grains of Goex.

The SSB's have a spitzer tip and a boattail bottom. They shoot real nice. I suggested them to another poster who owes a Black Diamond XR and he used them to take an elk last year...
