I have a stock rem 700 bdl in 300 win mag that shoots pretty well. My question is would there be any real advantage for me to move up to a 200 grain accubond over the 180's I am using now? My longest successful shot thus far is 637 yards on a cow elk(my target animal for these questions). I would like to work up to getting cvonfortable at 800 to 900 yards over the next few years. I'm just wondering if there is any real world advantage in jumping up in weight or would this just cause a little more kick and a little more drop at those ranges. Thanks for any input.
