Re: 6.5-284 or 257 Weatherby...update
I have 2 .257's and both are really great shooters. They are factory rifles. 1 a Japanese manufactured Lazermark, the other a newer lightweight. They both shoot the 115 ballistic tip very well. They like differant powders though. They both have been tweaked to perform at the level I expected. I've been trying to get to a 6.5/284 but just can't there yet as I say I have that range covered.
The thought of short action does keep bringing me back though. I too mainly hunt with my rifles. I don't shoot competetion. Although many of my friends do and they rave on the performance of the 6.5. One hunts with his bench rig, just sets up high and gets them 400-800 range. He shoots mainly in the 600 yard shoots(go figure).
I need to try those 130's from Richard Graves that Kirby Allen talks about.
You will like that .257 Weatherby, I'm sure. Good luck with it!
