Re: Long range hunting and target rifle!
Well here is my .02. So take it for what its worth. I really like the idea of benchrest 6mm's. This would be the 6XC, 6mm Dasher, 6mmBR. Let me explain why and then you can draw your own conclusion. These calibers were developed for maximum accuracy and efficiency in the cases that were developed. Originally they were specifically designed for short range competition from 300 to 600 yards. It has come to my attention as of this weekend confirming my suspicions and read knowledge that they can also be effectively used to 1000yrds. There have been world records set by the 6 Dasher, 6XC, and 6BR at 1K. With that said another advantage is barrel life. Where you might get 1500 to 2000 rounds of effective accurate barrel life from a .243 Win, .243AI and much less with the 6mm-06 (800-1000rnds), 6mm-248(500-800rnds). Another viable option that is going to hang with these calibers is the 6mmx47 Lapua(2000-2500rnds).
The less powder the less bore erosion you have the better your barrel life. The aforementioned 6mm-06 and 6mm-284 are what we call overbore calibers holding excessive amounts of powder causing extreme heat. In a tight bore, you wear your throat down at an accelerated rate. Some on here could give you more realistic numbers for accurate fire, but I have a feeling I am somewhere close.
The Dasher, XC, and BR are all top performers on a competitive level. I had the pleasure of meeting and talking with some of the guys using the 6mm Dasher. It is an improved version of the BR and produces 100 to 150 fps. One shooter said that having that extra 100 to 150 fps really makes a difference and can mean the difference between a 10x or a score of lesser value. I was seriously considering a BR for short shots, but now I am thinking the Dasher may be the way I want to go. I have been bitten by the 1K comp bug, so now I have to figure my next move.
You already own one of the top performers at this type of shooting that will perform with authority at the distances you would like to hunt and post nice targets at 1K. That would be the 300WSM. It was nice to see a bunch of them there and I own one. This caliber is really making a statement in benchrest competition and the hunting world. 500-700 yards is a chip shot for that caliber (not necessarily for the shooter, still need to practice).
So now that I have talked your ear off and really well over explained my way of thinking, I would choose the 6XC, 6Dasher, or 6mmBR due to their inherent accuracy especially at said ranges and will be able to push a heavy enough bullet to knock down coyote size game or less down at your presribed range with half the powder usage of the .243 and like cartridges.
