Cody- i agree with X-man. Accubonds have shot out of my remington senderos and sakos equivalent to match bullets. X-man has some experience here listen to him. you may have something loose. for black bear/ deer you could change bullets weights to 165 accubond . you need to make sure the scope mts or something is not loose. bench testing a 300 weatherby sporter weight without a break, i could do it; not as enjoyable as my 16 pound 6.5-284.
