[QUOTE="Frog4aday, post: 1691563, member: 9308"] Young Gun, you are thinking correctly - you need enough impact VELOCITY for the bullet you are using to expand properly. That's job #1. I think 1800 fps is a good, safe threshold for most cup & core bullets in .308 Winchester. Job 1a (meaning it's just as important as job 1!) is PENETRATION. Getting the bullet to expand is great, but if it comes apart 6" into the animal and stops penetrating, failing to take out the vitals, that's still a failure. So a 165 grain SST out of a .308 Win is probably going to do fine. They are a good match for each other. But fire that same bullet out of a .300 Win Mag into an animal 80 yards away, and that bullet might come apart and fail to get deep due to it's soft construction and the higher than normal impact velocity. I hope that makes sense. Bullet weight and construction should be a good match for the CARTRIDGE its going to be fired out of to minimize chances of failure. [/QUOTE]
