Misc What’s the largest caliber rifle that’s available in the open market?

I was scrolling through Reddit earlier and came across a historical post featuring a Boys anti-tank rifle. It got me wondering:
What's the largest caliber rifle you personally own?
And out of curiosity, what's the largest caliber rifle that's currently available on the market?
Looking forward to seeing everyone's answers and maybe a few pictures too.

Cheers

It's going to be some Mauser pattern bolt action chambered in an obscure magnum caliber that's less than 9000 joules.

10,000J and under and still good. A few skirt the limit.
