what are you wanting to accomplish? the 6.5/284 is an amazing long range round if you shoot high bc bullets and have plenty of twist. I have a 6.5/06....ballistic twins. I also have the 25/06 and 257roy. the roy is my choice for point and click, but I take my 6.5 out to the open country where I know shots will be long. it requires a range finder and ballistic research to reach its potential, but once you have done that it pretty much is possible to take shots into the 4 digit range. not that it can't be done with the 25's but the 6.5's have better bc and sd.
