Yea, I love the old .35. It shoots much flatter than it's given credit for too, especially with modern aerodynamic bullets like the Ballistic Tip/Accubond. Actual tests not taken from reloading manuals or magazine articles will prove that out too. It will hang right in there with a good 180 grain bullet from the .30/06 out to 300 yards or a bit more, and it punches a much bigger hole through whatever it hits. The great thing about the .35 is that recoil isn't much more than the .30/06 either.

For animals like the one above or any black bear, it can't really be beat. It just plain works.

Shuz-
You are correct on the twist rate for the factory guns being 1-16".
I haven't found any bullets that that rate doesn't stabilize yet, and I've tried them all the way up to the old Barnes round nose 300 grainer's, and they were definately long bullets.
