Barrel Twist vs. Bullet Weight

[Hoot]

Bill;

I'm just breaking into the 6.5G, having just finished assembling a 24" 1:9 barreled rig and my particular interest was also in the Nosler BTs. I'm no stranger to reloading and I'm at that point in a new caliber where I'm in the information sponge mode. Other folks more knowledgeable than me have advised using powders 12 or more steps faster than BL-C(2). You've been around the block. Elaborate on how to get all the energy out of slower powders. I always like to come in light, slow and work up on a new caliber.

Thanks,

Hoot
