I’ve heard you get better accuracy when your bullet touches the rifling. I want to do that on my deer rifle. Is there any problem?

Yes, you usually get better accuracy when you barely touch the rifling, but not always. Loads touching the rifling will increase pressures, so they should be worked up from a minimum load. Having said that, it’s still not a good idea to touch the rifling in a hunting rifle. You always have the possibility of pulling a bullet when you open the action, causing problems in the field such as a bullet stuck in the barrel and powder spilled in the action.
