Good luck however you decide Youngguy. I rest better when I'm on a camping trip or gone from the house knowing I have a layer of protection. A safe can be cut into in 20 minutes by battery operated grinders with a cut-off wheel. The burgler lifts the rifles out of the slit, puts them into his truck, and is gone while you are at the store. An alarm, dogs, and alert neighbors can help prevent that scenario. But if all else fails, I'd rather get $2,000 per long rifle from the insurance, than a big fat ZERO and a smoking hole in my safes.
I've told my story. Many other people have been robbed, thousands of burgleries in every town every year. To naievly think it will never happen to you is like thinking you'll never die or pay taxes.
To the OP, watch this on a 15 min safe breakin:
