Re: ? .338 win mag as a long range hunting rifle
Your A-bolt sporter is not a rifle that would typically have the ability to make kills at 1000 yards. But that doesn't mean that it will not. The cartridge will do it. All you can do is start working up loads and shooting further and further untill you reach the maximum potential of the rifle. With a good trigger, proper bedding, good scope and loads you should be able to reach 650 yards. After that hits in the kill zone are exponentially harder. Lots of difference from 650 to 800 and 800 to 1000. Your cartridge will kill elk at 800 yards. Just keep working until you are 100% on with shots in the kill zone at that distance. The 225 nosler accubond has a much higher BC .550 and would be a better choice for long range. I have taken numerous animals in the 600-800 yard range with a 338 winchester.
Predictions are difficult, especially when they involve the future
