Re: ? .338 win mag as a long range hunting rifle
I also agree with Wild Bill, in that the stated accuracy is NOT up to par for a LR hunting rig. The other issues he brings up are equally important. The scope you are looking into I commend you. The 5.5-22 NXS IS a great choice for a rifle you will walk to a log pile with a terrific view, & wait for an Elk. But if you are going to be packing it around, looking for elk I think it is too big, & I recommend one in the 12-14X range. Also the LRF. I have 2. One for steel @ long range, & another for hunting. The one I use for steel is a Swaro, & I love it, but for hunting it won't work for me. I have tried to range things with it , & just a smidgen of fog, or snow, it will read 13 yds. My Lupy LRF is much better at ranging things through a little snow, or fog, but several times it has also read incorrectly. For example,340 yds on trees that I know from ranging in good weather is actually @ 420 yds. So I don't trust them all the time under "hunting conditions". Add to that a little cosine error, & or cant, not to mention wind call, & you may have a wounded elk. In the time it would take me to cover the 420 yds to start tracking a wounded elk it will be in the next county.
Going back to the accuracy part. Don't take this wrong, as I don't know your level of skill, but I would want to know if YOU can hold sub MOA @ those ranges. The rifle may be capable of the necessary accuracy, & you just need more practice, & experience.
