Try some VMax bullets, with H335. We shoot them in the 40 grain version, but have tried the 50 and 55 with very good accuracy. We use the Fed.205M primers and mostly Federal cases. The VMax bullets are very effective on varmints and normally quite accurate.
Out of our Savages, the little 40 grain bullet will group 3 shots under 1/3 inch at 100 yards, with neck sized fireformed cases. However, if the throat in your gun is long, you may have better accuracy with the longer 50 or 55 grain bullets.
