[QUOTE="Varminator 911, post: 226561, member: 9705"] This is a tough question to answer when the length and weight of all the new bullets obviously aren't known yet. But I can tell you what I'd do, go with the faster twist. It really does depend on what you want to do. If you are satisfied with the 300 SMK or it's equivalent, then go with the 10 twist. But if you are hoping for more, something with a 0.9+bc, then go with the 9 twist. I'm waiting and hoping for an accurate hunting bullet of 265 to 280 maybe 300 grains with a bc above that magical 0.9. To have that bc those bullets will be nearly, or perhaps even longer than 2 inches. During the life of that barrel there might be a bullet that needs even faster than 9 twist. But 9 will get you a long ways. There is the possibility that say the 300 Berger cann't handle that faster twist due to a thin jacket. That's why I'm still waiting. Still hoping that a good Al tipped bullet will show up. But wanting to be prepared if the Berger looks the best. Hadn't heard that there was a 300 Amax on the way. The 510 caliber Amax has an Al tip unless I'm mistaken. They used to make a 7mm 162 Al tipped Amax but quit because it was tearing up their dies. Do you have any details about the 300 Amax? [/QUOTE]
