[QUOTE="hvy barrel, post: 77320, member: 4568"] The 6mm has a very slight ballistic edge over the 243, according to most of the debates & loading manuals I have read about it. The move from a 243 Win to a 6mm Rem would be a lateral move at best. It is my understanding that, in factory rifles, the 243 has a 1:10" twist barrel & the rifles labeled 6mm have a 1:9" twist. If the barrel is labeled as 244 Rem it may have a 1:12" twist & will not stabilize heavy bullets. Certain heavier bullets such as the 105gr HDY A-max require the 1:9" to stabilize. If you load your own bullets you might see a difference between them, but if you shoot factory loaded ammo only I don't think you will see much difference. The 25-06 is a cartridge based on the 30-06 case. Compared to the 243 Win which is based on the 308 case. You will have more powder capacity & the bullets will be the next size up in diameter & weight options. You can still use the 25-06 for varmint & big game duty. In short all 3 are excellent choices & if you handload your own ammo they can be used to hunt almost anything. I hope this helps. I have 2 6mm's & 1 243 myself & I enjoy them very much. I am still lookng for my first 25-06. [/QUOTE]
