I believe there comes a time in most men's life when they become confident in the equipment they use and such need to look elsewhere for the new improved go by the wayside. Outside of having a new toy most men will opt for there old reliable first. I used to study ballistic like it was a bible. It has helped me alot over the years guiding when the clients shots get long. But other than that for myself it hasn't done much.

Awwwwwwww the new caliber craze. Its fun its new but it don't really gain much.

I was at the gun shop when they got they're first 270 wsm's. The gun smith said this will kick a 270 win's ass. So I said okay let me see the ballistics. I laughed and they asked why. I told them I have been reloading 270 win at that speed for decades. Of course they looked at me like I was full of bull. Anyway new stuff may have an edge especially on factory ammo. But would I trade in my trusty300 win mag for a new untested 300 RUM I don't think so. Besides the animal is just a dead with either. HOW DEAD IS DEAD ANYWAYS. I guess you can always just blow something up.
