I just got off the phone with an AZ outfitter that mentioned, for the slightly easier draw unit in 2013, he can get me into some B&C-class bucks IF I'm able to pull off shots over 500 yards and in one area, between 600-750 yards across a mountain.
I have both a 270 Win. and a 300 Win Mag.; that said, both have 24" barrels and I was thinking of something different for next year.
Any other cartridges that might work even better at longer range? Maybe ballistically, a 6.5 or 7mm with lots of power?
Thoughts?
I'm going to go on a bit of a tangent so bear with me....
One can search my past posts or click on my signature to see where I stand on this, but ignoring anyones personal ethics, sportiness, etc., if you really want to be able to consistently make 600+/- shots it isn't going to be a cartridge change. The first question is what scopes/mounts are on your rifles? What are the
average 5 round groups at 100 and 300 yards? That's average, not every once and a while but what your rifle will do every single time with no excused flyers? What is your distance shooting experience?
I do not have any experience with the new 27 caliber bullets such as Matrix, but I do with just about every other caliber and given your two choices and the small size of Coues I would lean heavily to the 300Win with 155 Scenars. As I'm sure you know, Coues are small deer and I would say that an 8-10 inch target would be target size to work with. Given that, while not the most important criteria, drop will be important. The 155 Scenars will give a good balance between drift/drop at your ranges. Then get a scope that is truly built for shooting at long range. Not a rebadged hunting scope.
The most important piece of it, and the one that will have more bearing on whether you will actually have the skill to make 600-700 yard hits vice just talking about it, will be going to a course and getting taught how to do it by someone that honestly understands LR shooting at animals, and honestly knows what they're doing.
