Gday guys, I have worn out my barrel in my .308 and since I need to replace it anyway, I was thinking (a lot!) about rebarreling to either of these cartridges and would like to know the pros and cons of both in regards to long range hunting. The 6.5 has excellent accuracy and velocity but the biggest projectile you can get is 156gr whereas the 284 you can get 175 SMK's and reputedly very good accuracy. What I need is penetration and a decent wound channel for taking boars out to about 600yrds. Which is it to be?? Thanks in advance for the help! Cheers!
