My Extreme was not powder shy. It liked strong loads. One of the favorite with it was 110 grains of Triple Se7en 2f and a Barnes 250 grain bullet with the supplied sabot (Traditions sold them). That was a very accurate combination. It also shot shockwaves real well.

I traded the rifle long before I had a chance to really learn it... But from the little I did shoot it, it was easy to shoot, clean, and very accurate.
