BC,
I'm assuming you're talking about a safe.
Here in our local area a guy had his house broken into. He had a 600lb safe with 24 long guns, some hand guns, jewlery, memorabilia etc.... inside of it. He also had 6 more long guns in a wood cabinet next to it.
On Xmas day, while away from home, he was targeted. They stole his pickup truck out of the garage to move the safe. They stole the neighbors quad and trailer to move the safe from the house to the truck. They basically destroyed the guys house on xmas day. WTF.
I guess the reason I'm sharing this is to point out that if someone wants it they're going to get it one way or the other.
My vote buy another rifle instead and some itemized insurance.
