I only take out the bolt for transport to/from the range/hunting area because I sometimes stop at the 7-11 or gas station and if someone were to break into my truck and steal my gun, at least they wouldn't have the bolt. It's a pretty unlikely scenario, but it's my preference. My ammo is transported in my hunting pack, and my bolt is transported in the space under my front seat. Again, this is an unlikely scenario, but it's the way I choose to transport my bolt-action rifle. I store them in my house in my safe with the guns dry-fired.
If anyone has a way that makes better sense to them, I would be glad to hear it, and would gladly reconsider my current choice.
