Had nothing but good luck with 160 accubonds h4831 powder. Used this combination in a sako fiberclass 7 mag since about 2001. Whitetail, mule deer and elk also many many coyotes. I have never been led to believe terminal performance could have left something to be desired. Interestingly the coyotes suffered less damage then many I shot with varmint rifles(most of the time). To me this is one of the finest combinations I have used. I have messed around with many calibers and load combinations, but this is the one that ends up hunting with me more often than not.
